About an hour into the interview is when I ask him about the needle prick in her elbow
crease.
Joel, why is that there?
I don't know.
I asked him point blank that night.
Joel, did you inject your wife with anesthesia?
What?
No, I love her.
I love her. I'm Scott Weinberger, investigative journalist and former deputy sheriff.
I'm Anaseega Nicolazzi, former New York City homicide prosecutor and host of Investigation
Discovery's True Conviction.
And this is Anatomy of Murder.
All marriages have their ups and downs, and most couples will tell you that it takes a
lot of patience and hard work to make a healthy partnership endure.
When times do get tough, there are numerous ways to cope, from confiding in friends and
family to couples therapy to keeping a private journal,
all of which can be powerful tools for healing, and in some cases, powerful testimony to a
person's emotional state, or the state of a struggling marriage.
But of course, some marital discord can prove too challenging to overcome, especially when
it comes to infidelity,
abuse or other trauma.
And in those cases, a record of a couple's problems does not just become a window into
their private lives.
It can become evidence.
My name is Luis Mata, Jr.
I am a sergeant of the Laredo Police Department's Crimes Against Persons Robbery and Homicide
Bureau here in the Laredo Police Department in Laredo, Texas.
Growing up in Texas, Luis Mata thought he might one day become a sportscaster, but his
dad was a police officer right in Laredo and he never could get used to the idea of leaving
his hometown.
Laredo, Texas is a city on the southwest US-Mexico border.
We are a large city with a small town atmosphere in the sense that for having half a million
people, we still have a lot of people that know each other if you go to the grocery stores
and things like that.
That sense of community drew him to a career in law enforcement.
And as an investigator, he is often given access to the private lives of his neighbors,
especially when those private lives become embroiled in very public criminal investigations.
Case in point, the story of 31-year-old Maria Munoz and her husband Joel Payote.
Maria and Joel met when she was a nursing student and he was an ambitious nurse anesthetist
11 years her senior.
The couple married in 2011 and eventually moved to Laredo, Texas, where Joel built a
successful career and Maria dedicated herself to being a supportive wife and mom to their two sons. She was a very educated woman. She was actually a RN.
However, she never got the chance to practice because right after she
graduated she became pregnant and then that's when she basically became a stay
at home mom. To the casual observer, Joel and Maria appear to be a happy, attractive, and a
well-off family living in an upscale Laredo neighborhood, but looks can be
deceiving.
And when unresolved conflict is left to simmer just beneath the surface of any
relationship, the picture of a perfect marriage can shatter in an instant.
The picture of a perfect marriage can shatter in an instant. and kind of scared if she's not breathing. She may have taken some pills.
Okay, what is your address?
Joel described finding his wife, Maria,
unconscious in their bedroom.
He suspected that she had ingested
a dangerous amount of prescription medication.
Whether it was accidental or intentional, he didn't know.
I gave her a bottle of pills.
Okay, sir, and do you know what kind of pills they were? Yeah, one didn't know.
A uniform officer from the Laredo PD was first on the scene, and his body cam captured his encounter with Joel as he entered the house.
Hello.
What's going on?
The camera is on the bed.
But I can't feel a pulse.
Officer Dela Cruz found Joel
wearing his teal surgical scrubs,
performing CPR on his wife,
who was lying at the top of the stairs
near the master bedroom.
How long were you playing with him?
Like, maybe like 20, 25 minutes ago.
CPR was continued, but Maria was unresponsive.
Her eyes appeared fully dilated and she had no pulse.
Shortly after paramedics arrived, Maria Munoz was declared dead.
All the while, her two sons, just five and two, were still sleeping only a few feet away.
In the body cam footage, Joel appears visibly distraught and you can hear Officer Dela Cruz encourage him to sit down on a stool in the kitchen and
Try to explain what happened
She's been super depressed
She's been super depressed. I've been ignoring her
We're going through some problems
And I came to talk to, like we were just talking.
According to Joel, he had arrived at the house after his shift at the hospital.
He explained how he and Maria had been having some marriage trouble
and he had promised to come home to have what he called a heart-to-heart.
So you're not staying here right now? No.
We had sex, we took a shower, then I heard.
She was like knocked out.
What's up, what's up going on?
Joel claimed that Maria had been demonstrating
signs of depression for some time.
So his first thought was that she had overdosed
on clonazepam, and anti-seizure medication,
sometimes used to treat severe anxiety.
He even produced the near empty bottle
from an upstairs bathroom.
I got a call.
I got woken up at roughly just before 2 a.m.
The initial information that my sergeant at the time told me
was that we have a death and it was initially indicative of a suicide.
You may be asking why a homicide detective will be called to the scene of an overdose, accidental or otherwise.
But as Luis explains, it doesn't take a knife or a gun to make a death suspicious.
Contrary to popular belief, Laredo averages roughly 10 to 15
homicides a year.
So people think, oh, well, you only had 15 homicides a year.
You don't have to, you know, really, how much can you do?
The problem is we also investigate shootings, stabbings and deaths that we
deem have to be ruled out of foul play.
So a young person in her early th 30s passing away in her home without being ill,
that automatically sparks an investigation. Now, more times than not, it's undiagnosed medical
conditions, it is suicide, but we always have to go and do the death investigation.
Luis arrived at the scene and immediately got the rundown from the responding officer.
Luis arrived at the scene and immediately got the rundown from the responding officer.
I made contact with Officer De La Cruz, but Officer De La Cruz told me that the spouse, which is Joel Peyote,
he had said that Maria and him had had sex.
He went in to take a shower.
He came out.
He thought she was asleep.
And then he got dressed. Ten minutes later, he goes and checks on her
and she's unresponsive.
And he sees a bottle of prescription pills
that belonged to him.
So that he initially said that he believed
that she had overdosed on those pills and she had died.
But according to the officer at the scene,
there was some things about Joel's story
that weren't adding up.
What's the deal with like, they're lifting it up?
No, they've been separated, they've been going through some problems.
So he came over, they adiated, he was in the shower, he came out, he was like, he drug
her out here.
He said, he brought her out here from in the room.
I mean, that's just preliminary, I didn't get in depth with him.
But that's what he said.
So, um...
But why would she be out here?
But he brought her out here.
But he said that he thinks she took these YVs.
He went all the way into the medicine cabinet and brought these.
The officer showed Luis the bottle of clonazepam
that Joel had retrieved not from beside the bed where he found his wife, but from the bathroom.
The clonazepam was of Joel's, but the clonazepam bottle still had two pills.
When somebody overdoses, they're not going to leave two pills behind. They're going to take the whole damn thing.
But that wasn't the only thing about the scene that had gotten law enforcement's attention.
Hey, there's a needle right here. There has to be a vial somewhere. He gave us something. But that wasn't the only thing about the scene that had gotten law enforcement's attention.
Hey, there's a needle right here.
There has to be a vial somewhere.
He gave us something in the closet over here.
On top of that, the officer de la Cruz
found a needle on the stairwell,
and he found a wrapper kind of like what you find
syringes at a hospital facility.
Joel explained away the presence of needles and syringes
found in the house as just tools of his trade
as a nurse anesthetist.
But rather than giving Detective Modest comfort,
the fact that Joel was trained in administering
powerful medication only gave him pause.
Joel's erratic behavior was also attracting attention. He was sweating profusely through his scrubs,
and he was growing impatient with the police,
insisting that his wife had to be transported to the hospital
before the sun came up and before the neighbors began
wondering what had happened next door.
He was punching walls.
He was kicking furniture, and he was screaming. We were afraid he's gonna scare neighbors
and then once we found that Saranjh we're like hey, relax. Have a seat here.
Detectives are gonna talk to you. We can't have you all over the place either.
It's still a crime scene. But we emphasize that obviously and I go there
he wasn't detained at any point. He was initially told that, hey, this, you know,
we are completely sympathetic and understanding,
but we still have a job to do.
Joel was placed in the backseat of a patrol car
to calm down while investigators prepared
to scour the home for any potential evidence
that could either confirm or contradict
Joel's version of Maria's Southern death.
What threw a curveball was I couldn't exactly do a walk
through the home and the reason is because
remember as much of a death investigation consists of the
first thing that we have to do as investigators is we have to
obtain that we have legal authority to be in that home.
So when I arrived Joel was already outside in the back of a squad car.
So my first thing was I went up to him.
I introduced myself.
I expressed my condolences.
And then I asked a routine question was, do we have legal authority to be in your home?
As the homeowner, Joel had the legal authority to grant police or not his consent
to recover any evidence from inside the house. But to Luis's surprise, he denied that consent.
He says, why do you need legal consent? What are you going to do? Can't you just pick up
the body and go on your way? I said, no, it doesn't work like that. And I explained to
him, for example, if she overdosed, she has pills next to her, we need
your permission to be in there and get the pills because it is your home.
You have a right to your home.
And then I asked him why, what the issue was, is if he was scared.
And he says, no, I live a very private life.
All I need you to do is just, you know, get her body and get out of here.
So that's fine.
I said, that is absolutely your right.
Nobody's going to go inside.
We're going to secure the crime scene while we apply for a search warrant.
It sounds suspicious, right?
But as a prosecutor, I always have to think about it from the other side too.
Some people are just not fans of law enforcement, and there's always the possibility that he's
just scared or traumatized and his refusal to cooperate with police is not an
indication that there's anything sinister going on at all. And I think
I've had that happen in my experience in law enforcement and you know I kind of
give somebody a little bit of a side eye but I don't really take that much into
consideration but this is where an investigator's experience
and intuition come into play. I had been doing that by that time almost three and a half,
four years. And obviously at that time, I had been in law enforcement 15 years. I completely
understand most of the time it's a grieving spouse and I'm respectful of that. But there's
a difference between a grieving spouse and I'm respectful of that. But there's a difference between a grieving spouse
and someone that has something to hide.
Joel soon realized that his attempt not to make a scene
actually did exactly that.
They made a crime scene.
So I told the officer, let's get the kids out.
Nobody goes in, put yellow tape around it,
it is now a crime scene.
And he said, well, what happens if the son comes up? And I go, well, if the sun comes up, Joel,
well, the sun comes up. He goes, well, our neighbor's going to see everything.
And I said, yes, because they, this is going to put a delay in it. I mean,
you're delaying it. That's fine.
But if we have to hold the crime scene for a couple of hours and your neighbors
see, I mean, we can't control that. No, no, no, no, I live a very private life.
I don't want as much attention on this.
I'll sign it, I'll sign, I'll give you the consent."
So he changed his mind and he signed the written consent.
Luis led the search of the house and it was immediately clear
that there were no signs of any kind of struggle
or domestic abuse, no overturned furniture or broken glass, signs that may
have indicated that Maria and Joel had gotten into a fight.
For starters, Maria was a very organized and clean person.
I say that because my wife is a clean freak and she reminded me of my wife in the sense
that it was everything was so organized, very clean home.
But that's not to say that there weren't things that seemed out of place, starting with Maria's body itself. If Maria had passed away in bed, as Joel had claimed,
why was her body on the floor at the loft at the top of the stairs? And then there was a state of
the bathroom in the master bedroom, which was conspicuously clean. Joel's first statement was
that he was in the shower. And when all this
happened. So what happens when you take a shower, for example, what are you going to
notice in the restroom? Condensation, steam, mirrors sometimes smeared for
whatever reason with water, a soaked towel, a damp towel, the smell of soap, the smell of shampoo. That restroom was dry, absolutely dry.
It looked like it hadn't been used and it looked like it had been cleaned at 8am,
9am and hadn't been moved since.
There was no restroom that had any evidence of a shower being used.
And if Joel had showered as he claimed to have, why was he back in his work scrubs when
police first arrived?
He had already told me he arrived in scrubs, which is understandable.
He's a CRNA.
He just got out of work.
I go, you just took a shower.
Why did you change back into scrubs if it's your home?
And he thought about it and he said, well, it's because I'm not supposed to be here.
And I said, well, this is your house. What do you because I'm not supposed to be here and I said well this is your house what do you mean you're not supposed to be here it goes
oh it's cuz I have a girlfriend somewhere else and she doesn't know that
I'm back visiting my wife my wife and I were separated and with that a key piece
of the puzzle was revealed not only were Joel and Maria separated,
but Joel had a girlfriend.
And if investigators were able to uncover evidence
that Maria's suspicious death was the result of foul play,
the revelation of infidelity or a possible love triangle
could be the first hint of a potential motive.
On September 22nd, 2020, police and paramedics were called to a house in Laredo, Texas, where they discovered the lifeless body of 31-year-old Maria Munoz. According to her husband Joel, Maria's death was likely the result of an intentional overdose
on a powerful prescription medication.
But evidence found at the couple's home was starting to raise suspicions about his story.
Maria's body showed no signs of physical trauma, no bruises or cuts or blood on her
or anywhere in the house. So you can imagine
the results of an autopsy would be crucial in determining the exact cause and manner of death.
But in the meantime, investigators hoped Joel could help shed more light on his wife's mental
state and the circumstances surrounding her apparent overdose. So at that time, while he gave us the consent, we went to go interview him at the station
so that we can get just some background information about his spouse, which is very routine.
In the moments before the interview started, cameras recorded Joel alone in the interview
room.
And I have to say, he'd demonstrate some bizarre behavior, even when you consider the
fact that just hours before he had lost his wife.
He was pacing, crying, even slamming furniture.
And in a way, something you can't put into words, but when you watch it, just something seems off.
And of course, you can never predict exactly how a grieving husband might react to the loss of his wife.
might react to the loss of his wife. But as a detective, you can compare his behavior
to hundreds of previous experiences to conclude that this was out of the ordinary.
And in a homicide investigation, anything out of the ordinary is suspicious.
I start off my interview with just the backstory of both of their relationship.
And then I got the information as far as why they were separated.
And he confessed to me that he had fallen in love with a coworker of his.
And she had found out about the affair back in April.
And they had agreed to separate until he, quote, decided what he was going to do.
The co-worker's name was Janet,
and it was her house where Joel had been staying.
But according to Joel, he and Maria had made plans
to have what he called a final heart-to-heart
about the state of their marriage.
And that explained why on that night,
he had driven to Maria's house, not Janet's,
after getting off of work.
I asked him for the events that transpired that day that led up to the death.
And that is when I realized that he could not account for his time period.
The most simplest questions of them all, such as, what time did you arrive?
Well, I don't know.
Okay, what did you do when you got there?
Oh, I can't remember. I don't know. Okay. What did you do when you got there? Oh, I can't remember. I don't know. I go did you shower?
Yeah, which restroom did you use the master restroom? Okay. Why isn't there any steam there? Oh, I don't know
I don't know. Why are you I don't know. I don't know. I don't know that was for everything. It was I don't know
According to Joel the couple had made up and had actually slept together before he
supposedly took a shower and then discovered her unconscious body in their bed.
And I asked, well, why if she was on the bed, did she end up in the loft?
And he thought about it and he said, I needed a flat surface.
Okay, well, why wasn't the carpet or the floor on your
bedroom used? Oh, I wanted to give the paramedics easier
access so they can go straight up.
When asked about the syringes and IV equipment found in the
home, Joel initially said they were work related, but couldn't
explain why they were located outside of his medical bag or
why he would have brought his medical bag into the house to begin with. I asked him did you work and he said yeah he worked. I
go what time did you get out? I don't know. Well more or less I think at four or
five. Okay where'd you go afterwards? I don't know. I don't know. Why are you
asking me this? Like I'm my wife died. And so he started becoming evasive and defensive.
And remember when I said that Maria's body showed no signs of physical trauma? Well,
as it turns out, that wasn't exactly true.
While I'm there interviewing Joel, I find out that there was a suspicious needle prick mark on Maria's elbow crease. One mark, one, not indicative of someone that uses repeatedly.
It looked like it was fresh.
It looked like somebody had just drawn blood from her.
That was suspicious.
And we found out that the hermetic that responded did not start an IV.
So what in the hell is that Mardu in there?
Why is it fresh?
As an anesthetist, Joel administered IVs for a living,
and police found both the equipment
and the drugs of his trade in the house.
A very dark picture of a potential crime
was starting to emerge.
About an hour into the interview
was when I find NY confirmed,
and I ask him about the
needle prick in her elbow crease.
Joel, why is that there?
I don't know.
I asked him point blank that night.
Joel, did you inject your wife with anesthesia?
What?
No, I love her.
I love her.
There was another disturbing fact that was not lost on Detective Matta.
While Maria's body was being transported
to the medical examiner and Joel was being interviewed by police, their two
sons, just five and two, had been placed in the custody of child protective
services. At no point did he say I need to go back to my children there without
their mom. No. You know what his primary reason that wanting to leave was?
He needed to go get to Janet.
I need to go to Janet's house.
Can you drop me off at Janet's house?
Keep in mind, their sons just lost their mom.
But that was not his focus or his concern.
His concern was to get back to his mistress.
However, pending an autopsy and a full toxicology report,
investigators still did not know the
cause or manner of Maria's death.
So even if they did suspect foul play, and clearly they did, there was still no evidence
that a homicide had even taken place.
And for that reason, Joel was released.
He begged the officer to drop him off at Janet's, but the officer didn't.
The officer took him back to his house.
And while he's over there, I'm at Janet's house.
So he was trying to beat me to Janet's.
Just a few hours had elapsed since Maria had passed away
from causes still unknown,
but Luis was eager to meet Joel's love interest
and get her statement before she had any chance
to possibly communicate with
Joel. So I write to Janet at six in the morning. I ring the doorbell. She has a poodle or some type
of schnauzer dog that was barking away and she never answered the door. Apparently she called the
police on me saying that there was a man outside ringing the doorbell repeatedly
and when the dispatcher told her it's one of our detectives that's out there
wanting to speak to you it still took her roughly 10 minutes to come down and
then she came down and she agreed to be interviewed at the station initially yes
she seemed adamant of wanting to know why what's going on
I go well we'll tell you at the station. She kept asking, what's it about?
Nigga, we'll tell you at the station.
I am a firm believer that you can often learn more
from someone's reaction to news
than you can from their actual words.
And according to Luis,
news of Maria's death did not seem to take Janet by surprise.
What did was the fact that police already knew
about her relationship with Maria's husband Joel.
She initially was reluctant to say that she had a boyfriend.
She finally aggrorperated that she had a boyfriend, Joel,
and she was initially under the belief that he had gone to work.
Janet admitted that Joel frequently stayed at her house,
but denied seeing him before or after
Maria's estimated time of death.
I released Janet at roughly 7.30 in the morning,
and she agrees to be cooperative.
And I said, Janet, if needed,
will I be able to get video from your home
that just shows the ins and outs of that night?
And in my mind, I wanted to make
sure that if, because it was already getting suspicious, if this is a homicide, I want to
find out if Joel had been going back and forth or if Janet participated and they came back after
the death to stage it together. But 48 hours later, Luis received a phone call not from Janet, but from a local attorney.
Says, Janet's retained our services. She's not going to talk to you anymore. If you need anything, talk to me.
And this is where the lawyer has to chime in and say that retaining a lawyer is anyone's right.
And it is by no means an indication of guilt.
But of course, from an investigator's point of view, any perceived obstacle in an investigation does tend to fuel suspicions.
We had suspected the possibility that Janet, whether directly or indirectly,
was a participant in this.
Whether it was by destroying the anesthesia, getting rid of the evidence, having knowledge.
We suspected something that she knew
that she wasn't telling us.
Joel had claimed that despite their separation,
there was no bad blood between he and his wife
or Maria and Janet.
But when police subpoenaed the ring doorbell footage
from Janet's house, they found evidence to the contrary.
Footage from just three days before Maria's death showed Maria
arriving at Janet's home, banging on the door and demanding that Joel
come outside.
So she was going to confront them both to A, catch Joel in the act,
catch him in his lie and B, confront him with the news that she's getting a
divorce. However,
she never, neither Joel nor Janet answer the door. So Maria leaves.
But that's not the end of it. Even as Maria was leaving, Janet escalated the situation.
While Maria leaves, Janet calls the police department on Maria and says that there's
the ex-wife, this is what she described, the ex-wife of her boyfriend harassing her and outside her door. So that prompts an
officer to get dispatched there. So Joel's gone by the time the officer
gets there. The officer talks to Janet, he goes, okay look, what I can do right now
is give her what's called a criminal trespass warning so when the officer
calls Maria hoping to talk to her, you can
hear him in the background, hang up the goddamn phone, I'm talking to you. And he's in a rage
and Maria hangs up the phone.
So Anasiga, this clearly is some direct evidence that the story that Joel was giving that the
separation between he and his wife were amicable. This also shows that Joel's girlfriend, Janet,
was learning just how much Joel's wife
didn't know about the relationship.
I mean, look, it's clear that it was contentious.
Maria's not happy, and in Joel's eyes,
she's giving him a hard time,
whether it's because he doesn't want to lose her,
doesn't want to lose Janet,
or just doesn't want the headache of a divorce.
I mean, who knows where that lies,
but one thing does seem clear,
and that is that he was angry. But still, investigators did not have the
evidence to prove that Joel or Janet were involved in Maria's death.
That was the most frustrating part. And to Maria's family's credit, they understood and
they were so patient. We were waiting for the toxicology. Yeah, Joel's free. He's not
charged.
And unfortunately, getting the results of that full tox screen was going to take weeks,
not days. But that didn't mean that detectives stopped investigating, focusing especially
on whether Maria was displaying warning signs of depression or self harm in the weeks prior
to her death.
So during that time, we're interviewing many, I want to say, character witnesses.
And according to those people who knew Maria, including her sister and close
friends that she emailed with regularly, Maria had never contemplated taking her
own life. And while she was upset over her husband's infidelity, she was also
resolved to move on with her life.
In fact, Maria had even begun making plans to restart her nursing career,
studying to recertify her credentials in Texas.
Not exactly the actions of a woman planning to end her own life.
But the most telling information was provided by Maria's own journal,
one in which she routinely confessed her private thoughts
even in the days leading up to her death.
The diary revealed years of pain, betrayal,
and emotional abuse suffered
at the hands of her husband, Joel.
But it also showed her resilience
and a determination to leave him,
with no indication that she was severely depressed
or suicidal, as Joel claimed.
In addition to Maria's journal, investigators were able to search her phone records and
recovered numerous messages between Maria and her friends documenting Joel's violent
outburst and her fears of his growing hostility.
One chilling text, sent just the night before her death, read,
I just ask if you can pray for me. Tonight, we are going to talk.
What was going to rule everything was a toxicology,
and it wasn't a standard toxicology
that our medical examiner checks for.
This toxicology was going to go more in depth.
The growing consensus was that Joel
not only had the opportunity and the means,
he had the motive to somehow deliver a fatal dose of drugs against Maria's will.
And Luis expected the tox screen would help prove it.
I'm anticipating it's going to show high potent anesthetics that are only found in a hospital setting.
I was confident of that. The hardest part is proving that
he injected her and that she wasn't a willing participant.
In other words, the tox screen may show cause of death, but it would not necessarily prove
the manner of death, specifically whether it was homicide, death by suicide, or accidental.
Poor Dr. Stern. I was being an annoying guy. I called her every day for almost a month straight.
And then finally, four months after Maria's death, the results were in.
She reads it and she says, okay, no clonazepam. That's very important.
Instead, her system showed a deadly cocktail of six other powerful drugs.
Positive for propofol, demerol, versed, narcan, lidocaine, and ketamine.
These of course are not over-the-counter medications.
Some of them are powerful surgical anesthetics that are rarely administered outside of a
hospital setting. And propofol in particular, which was determined to be the main cause of death, can only be
administered by injection.
There's just no plausible reason why Maria would have had access to those drugs.
More importantly, the results of the talk screen directly contradicted statements Joel
had made to police.
So he just kept saying she was very depressed.
She was drinking every night.
She was on a very hard depression.
Okay.
Well, we find out during the toxicology that she had zero alcohol.
The fact was it was Joel Peyote who had access to these powerful drugs. He had the tools to administer them and he had the knowledge of
exactly what they would do.
We had interviewed several of Joel's coworkers who are actually CRNAs,
same profession as Joel.
And I remember asking one of Joel's supervisors, I said,
do you guys have the ability to kill us if you wanted to?
Without hesitation. Oh hell yeah. Hypoth kill us if you wanted to without hesitation? Oh hell yeah
Hypothetically if you wanted to kill me if you wanted to kill somebody
How would you do it?
And he said you know what I do if you really want to do it you get somebody on ketamine and then you just go
To town with them after that that ketamine will put you to sleep
Ketamine and I remember him saying that ketamine is the most potent thing once you have them on ketamine
It's fair game. You can do whatever you want with them.
A toxicology report revealed that Maria Munoz had a fatal mix of several powerful drugs
in her system and a single injection
mark on her inner arm hinted at the delivery method.
Without hesitation, our prosecutors and I, this is murder.
This is cold-blooded murder at the highest degree.
But if this was indeed a homicide, the only question that remained was how her husband
could have injected her against her will.
The toxicology report also showed us was that Maria had a high amount of caffeine.
Maria was a big avid fan of coffee.
I believe that he spiked her coffee and then went to town, got her unresponsive, got her
in a paralytic state.
And once she was under the influence of ketamine and some Versed that's all tasteless,
he went to town and he killed it with propofol.
The official cause of death was determined to be acute intoxication,
but the medical examiner listed the manner of death as undetermined.
In other words, there was nothing in the autopsy or toxicology that could definitively prove,
however unlikely, that these medications were not
self-administered.
The problem that Dr. Stern had was
we needed to prove that Maria was not a willing participant.
And that's when we just present our evidence,
present our case before a jury.
So you know, Scott, and you say this all the time, you have to think about this
from the defense perspective before you go into court or even file the charges.
In many cases you should.
And I can also see it if I'm looking at the other way, at least you have to be
able to think about they're going to come with this, like that she is so distraught
because of the marriage breakup, him being with this other woman that it's almost like, Hey, you know, please, like, I love you, you don't want to be with me,
like, please end this for me. Like, you can make it painless, you know how to do that.
Or maybe they were like taking drugs together, he gave her too much. Doesn't sound like that
to me at all. But it is things investigators need to rule out, because the defense may
well go there if they don't.
And if the science, Ennesega, can't help the investigators here make this determination
of whether it was self-inflicted or whether it was intentional, which would be homicide,
they have to have a snapshot of her life and talk to the people closest to her and get
really a determination of where the marriage was.
What was her life like at the time?
Was she severely depressed?
Was there any indications or examinations
that she may have had prior to her death
that indicated that she may be interested
in taking her own life?
And you have to combine that part of the investigation
with the science part of the investigation
to really make a determination of where you go from here.
The challenge in this case for prosecutors, the biggest one, it wouldn't be proving who killed
Maria Munoz if that was the fact, but if a murder had been committed at all.
There was significant circumstantial evidence to help make their case, but what they really needed
was corroboration. And eventually, that's exactly what they got.
We had our ace in the hole and ended up being none other than Janet.
And with the realization that she could be held accountable for withholding key evidence
or possibly even being complicit in a plan to cover up the murder,
Joel's girlfriend was convinced it was time to make a deal.
So our prosecutor, who we have a great relationship with, reached out to Janet's council and we made
an agreement that if she, in exchange for her testimony, in exchange for her being a witness,
she was kind of given an immunity.
The one exception to that immunity deal
being if prosecutors discovered she had helped to plan,
carry out or cover up the murder.
So Janet took up that offer and became our witness.
And once we got the toxicology back,
she came in for an interview
and she confessed to us that Joel had basically
gone over there to talk to her and he injected her.
According to Janet, Joel had claimed that Maria's death was not suicide or homicide,
but rather a terrible accident.
His side of the story was that he went over there to tell Maria that it was over, that he chose Janet, that he's in love with Janet.
And he told Janet that when he told Maria that, that Maria started having an anxiety attack and started screaming.
So that he calmed her down and said, here, take some ketamine, relax, and that she just passed away accidentally. But he conveniently left out the rest of the deadly drug cocktail found in her system.
And Peyote's attempts to cover up this supposed accident, lie to police and get rid of damning evidence
also belied his claims that he did not kill his wife.
I did ask her, I go, did you get rid of anything? And she said, I believe I did, but unbeknownst,
because when he came back, he brought a bag
that he had hidden, and I threw it away.
What that bag contained, she's like,
I believe it contained the medicine
that he injected her with.
But I didn't know that at the time.
Janet's account of Payout's actions
painted the picture not just of a manipulative, abusive
husband but a cold, calculating killer.
In March of 2023, after four months of investigation, Peyote was arrested and charged with the murder
of his wife and mother of his two children, Maria Munoz. We're gonna police, and we're gonna break down the door!
The other right to remain silent.
In his trial, prosecutors would argue
that Peyote intentionally and deliberately
incapacitated his wife and injected her
with a deadly mix of powerful drugs,
then attempted to stage her murder as a death by suicide.
The defense was that Maria and Joel would do drugs together, that they would having
marital problems that they resorted to doing anesthetics recreationally. And that on that
night, Joel administered Maria, but it was an accident that she passed away.
Witnesses refuted this claim that Maria was a drug user,
and after his pattern of lying to police,
Peyote's credibility was shot.
About the only thing Luis believed was Peyote's admission,
that it was him that administered the deadly injection.
Right off the bat, I was ecstatic inside
because just by me getting him to say that he injected her,
I knew and I was confident with our because just by me getting him to say that he injected her,
I knew and I was confident with our prosecution team and our investigators.
We were so certain that a jury would see right through this killer's eyes and find him guilty.
Just by him even admitting that he injected her.
As for motive, prosecutors argued that it went beyond Peyote's desire to be with another woman. They believed his motive might have also been financial.
I believe when he found out that she's going to go to an attorney, that attorney is going
to do what's best for his client.
So what is she entitled to in Texas?
50 percent, 50 percent of his assets.
And I can tell you this, that CRNA position is probably the highest, if
not one of, if not the highest medical positions, salaries that you can have in Laredo because
there's so much in high demand that they give them so much bonuses. We believe that Joel
was grossing maybe $600,000 a year. So imagine
Maria taking half of that. Plus, Joel had properties in San Antonio, Texas. He had
assets of properties here. He had land. So I believe that's he came to the
realization that, you know, Maria was gonna take him to the house on the
financial side and I don't believe that he could accept that. The jury deliberated for less than an hour before delivering their decision.
45 minutes, we came back with a guilty verdict. The punishment took a little bit longer,
about three hours, and we were able to secure a 99-year sentence.
Throughout the trial, Peyote refused to admit any wrongdoing and showed
little remorse for the murder of his wife.
refused to admit any wrongdoing and showed little remorse for the murder of his wife. Joel, throughout the trial, would pretend that he was crying.
And I don't believe for one second that during the trial, that those tears were real
because they were the same type of tears that were shared the night of the incident.
However, when Maria's sister, Marisol, looked Joel in the eye and told him,
I loved you like a brother and this is how you repaid us. Maria loved you. Maria loved you and
would have taken a bullet for you. She died literally for you and for you to kill her.
That is the only time in the investigation of me having this case for up to that point, three years,
that Joel's tears were real because he broke down.
For at least a moment, he realized what he'd done.
Another example of how powerful and necessary victim impact statements can be both in sentencing
and bringing a sense of justice for the survivors of deadly violence.
People ask, well, how can you do this?
No, how can you see what you see and then go home?
And yeah, I'm not going to lie to you, sometimes it's tough in what you see.
But when you get justice and you put a lot of hard work into a simple case that starts
out as an overdose suicide death, and it leads you to this and you see the satisfaction
of bringing justice for your victim, you know, it makes it all worth the while.
Here was Maria carefully documenting her thoughts, fears, and daily life in the quiet pages of
a journal, likely never imagining those very pages could become the key to uncovering her own killer.
The true irony is that Maria's thoughts, those private moments, the ones she
believed no one else would ever see, became the very thing that brought her
justice. It's as if Maria reached out beyond the boundaries of life and death,
her words, and led investigators to the truth she could no longer speak. Maria Munoz was a mother, a wife, a woman navigating her way through a marriage that
wasn't working, with a husband who was in a relationship with someone else.
None of it's easy, and unfortunately too many people understand the type of pain Maria
was living.
But that's the key.
She should have lived.
She should have left him or stayed.
They should have divorced or not.
But that's it.
That's the type of decision people in relationships make,
whether difficult or no longer viable.
Those are the reasonable choices for every person to consider.
Not murder.
Not taking a mother from her young kids. Not
taking a woman's life. Maria Munoz, we remember you. We hope that your boys are well and that
they remember your strength. All the good qualities you surely pass down to them. And most importantly,
that they still remember and feel your love for them both.
