DNA, when used correctly, can be an extremely useful tool when it comes to matching a suspect
to a crime.
In many of the cases we've covered, the reason that it went cold was because the DNA technology
we use now wasn't available to the original investigators.
This is one of those cases. The original detectives used the
investigative tools of the time, but they simply weren't able to connect the killer to the crime.
Cold case units like the one in Fairfax County, Virginia, apply today's science to previously unsolved cases.
From A&E, this is Cold Case Files.
I'm Brooke, and here's the impeccable Bill Curtis with a classic case, A Knock at the Door.
This is the Cold Case Homicide Office.
It's part of the Homicide squad in Fairfax County Police,
and this is where we store a number of the cases that were...
Steve Malefsky and Bob Murphy are cold case detectives
for Fairfax County, Virginia.
These photographs only represent a small number, and we were...
Tacked to the wall of their squad room,
the faces of some of their victims.
It's sort of a matter of respect to these people that they're here,
and it's our responsibility to find answers to their deaths.
Any homicide detective will tell you they have their cases
that are really at the top of their list of what they would like to solve.
One of those for me is this one.
It's a double homicide of a couple here in Vienna, Virginia, back in 1997,
and this case is still open.
This little boy here was found dead, naked and dead, in a stream in Fairfax County in 1972, I believe it was.
We have no idea who he is, just a little boy. He's maybe four to six years old.
In the winter of 2004, Murphy and Malefsky pulled out the picture of another victim.
Her name is Mona Lisa Abney,
and she was murdered in 1978.
That's Mona Lisa Abney, a beautiful woman, you know, smart and everybody, the kind of
person everybody likes. You know, just a sad case that she came up here to Northern Virginia
and was killed in a hotel room. It was called by the communications section that said that there was a homicide at the
Tyson's Corner Holiday Inn.
Scott Boatwright is a crime scene technician for the Fairfax County Police.
On January 28th, he's called out to a murder.
Apparently, a maid came in to clean the room in the morning and when she
entered the room she found the victim. Inside room 722, 25-year-old Mona Lisa Abney lies dead
on the floor. She was nude basically from the waist down and she was kind of lying on their back automatically you would think she was been raped the room appears to be
ransacked and Mona's cash jewelry and credit cards are missing main thing
you're looking for is fingerprints because back then that was our DNA was
fingerprint so the big emphasis hair fingerprints Boatwright dusts for prints, bags the evidence,
and photographs the scene.
Then it hits him.
The ransacking is staged.
The chair was turned over.
The lamps were just turned over,
but not really damaged in any way.
Maybe someone did this just to make it appear
that there was a tremendous struggle.
You kill this woman, and yet you don't want to break the land.
A medical examiner establishes the victim was raped and strangled.
Semen is collected, as well as an unknown Caucasian hair.
Meanwhile, investigator Ron Yeager arrives at the Holiday Inn
and begins to work the building room by room, person by person.
Well, everybody's a suspect, from management right on down to the employees, guests, so on and so forth.
We went through the entire roster of people that were there.
One of the people investigators talked to, a hotel maid,
who claims she let a man into Mona's hotel room an hour after she checked in.
She said she let him into Mona's room because he said he didn't have his key and he didn't want to wake her.
Basically what she explained was a white male, about six foot or more, very stocky build, like a football player.
An artist works with the maid to develop a sketch of the man.
Meanwhile, the phone in Mona's hotel room rings.
At the other end of the line,
a man named Wilbert Abney.
He mentioned who he was.
He said he'd been trying to reach his wife and couldn't.
And I said, Mr. Abney, I said,
I can't tell you anything about it right now, but your wife is deceased.
He wasn't emotional.
It wasn't emotional or anything like that.
Abney drives two hours to Fairfax County,
IDs his wife's body, and gives a statement.
His cold demeanor is startling to investigators,
as well as to friends and family.
It was a Sunday evening, early Sunday evening,
that we got the call from him.
Patricia Parker is Mona's friend.
And it was Wilbert.
And I said, what's going on?
What's wrong?
He said, Mona's dead.
And I just lost it.
You know, I said, you know, you've got to be kidding.
No, no, I just lost it.
And he said, no, Mona's dead.
He was so relaxed.
When he said it, it was like, she's dead.
For Parker, the grief runs deep.
So, too, does the suspicion that somehow Wilbert Abney was involved.
It was no sadness.
No sadness at all.
Just as if he's calling to say, you know, it may rain tomorrow.
And as upset as I was, something just didn't sound right to me.
You have a question in your mind.
Is the husband involved?
Things don't look necessarily that way,
but is he involved in having somebody else do the job for him?
But Abney looks nothing like the suspect sketch.
As you can see, it is nowhere as close to this gentleman, not a difference.
Still, Yeager's suspicions are heightened
when Abney tries to collect an insurance policy
taken out just a few weeks earlier.
I think it was 100,000 double identity,
which set him up very well.
We learned who signed the policy.
It was a forgery.
His wife didn't sign the policy.
It tells me we have more motive now.
Abney sues the insurance company for the funds, but loses the battle in court.
Meanwhile, Yeager unearths another red flag.
Abney was having an affair.
When Yeager interviews Abney's girlfriend,
she recalls a phone call from Abney the morning Mona was found murdered.
It was about 9.30 that morning that he
called the lady and told her that his wife was deceased. About an hour later, I get the call
from him. And that's when I tell him that she's deceased. So he has knowledge of her death before he ever talks to me.
That's when I realized, I said, that this man is my man.
More and more fingers pointing in the right direction,
but you can't put the man in the room.
If you can't put him in the room, you can't charge him.
Abney passes a polygraph and provides prints and hair samples.
None match up to the evidence.
So that's where we came up short all the time, on things that would get a conviction.
Meanwhile, the hunt is on for the white male spotted entering Mona's hotel room.
We put out the information, like the teletype and so forth.
One of the guys on the police department worked homicide, came up with an individual,
and asked me, he said, you might want to take a look at this guy.
This guy is Michael Grotto, a man being held in another county for assault charges,
and a man who looks eerily similar to the sketch.
Mainly the eyes, very similar, enough to be honest to the sketch. Mainly the eyes. Very similar.
Enough to be honest to say
that this could be this.
During a live lineup,
the maid fingers Grotto
as the man she let into Mona's room.
The trail is once again heating up.
Detectives get a search warrant
for Grotto's hair.
And that was sent to the lab in Virginia.
And they said there was a lot of similarities,
but not a match.
Grotto is eliminated as a suspect.
Detectives are left with a lot of suspicions,
but not a lot of answers for Mona Lisa Abney.
A lot was taken other than just a life,
you know, her future.
A future that would have been probably a big asset to the family.
I'm sure they're very proud of her.
It's a shame. This lady would be a benefit to society.
Very, very frustrating.
Very frustrating. I just felt that she was done a great injustice.
Mona Lisa Abney's murder is boxed up
and shipped to the cold files,
where it will stay for more than two decades,
until two cold case detectives pick up the case
and catch a break.
I think we've got something to work with here, forensically.
They were perfectly preserved, they were dried,
so the evidence from 1978 was still on those swabs. the evidence from 1978 was still on those swabs.
The evidence we needed was still on those swabs.
Mona's husband, Wilbert, was the initial suspect the investigators focused on for her murder.
He had taken out a life insurance policy on her just weeks before her death, and he was having an affair.
The thing was, he passed a polygraph, and his fingerprints and hair samples didn't seem to match the ones at the scene.
That was the science of the time, and the investigators had to let him go and look for a different suspect.
This is the police property room where we keep cold case evidence. There's rapes and murders and some other crimes here. In an old jail in Fairfax County, the ghosts come calling.
Murder unsolved and sometimes forgotten.
Items of evidence that speak of lives largely unlived.
We've got somewhere in the neighborhood of 75 open cases.
And they go back to the late 60s.
This bicycle here belonged to a little girl.
I think she was about 10 years old.
Right. This little girl's body was found, I think, under a bush, and she had died of suffocation,
and her bicycle had been found several days earlier, and it's just extremely sad.
Every time I see that bicycle, you know, I think of her. A lot of these boxes we've touched, like this case right here.
All these boxes represent a family that was killed in 1999.
There was a triple murder in 1999 of an entire family, a husband, a wife, and their 16-year-old
son.
For every one of these boxes, there's a human tragedy.
There's a story here to be told with all these boxes.
And that's our job. That's what we do. If we can resolve these and hopefully one day move these boxes out of here,
ultimately that's our goal.
In January of 2004, Murphy and Malefsky pull out a box from 1978
with the name Mona Lisa Abney scrawled on the side.
Right, she was a young woman in her mid-twenties, came up to Washington, D.C.
area to do some shopping at the
Tyson's Corner Mall, and she
was found strangled to death in her
room by a maid.
Detectives dig through the evidence,
looking for a lead.
There's some documents, it looks like, that
they collected in the room.
They're probably documents that were in Mona Lisa's handbag
or found on the bed.
Here's your hair slides.
When detectives pull out a rape kit,
they know they're in luck.
We've got something to work with here, forensically.
They were perfectly preserved. They were dried.
So the evidence from 1978 was still on those swabs. the evidence from 1978 was still on those swabs.
The evidence we needed was still on those swabs.
This is the main examination room that we have here in our forensic laboratory.
The swabs are sent to Mary Green at the state crime lab.
Yeah, there was no mold, there was no indication that there was degradation visually on the sample, so it seemed hopeful.
Green detects a presence of semen and is able to extract a DNA profile.
Cold case detectives have their first break. Now they need a suspect to match up with their profile.
Every police department has these police reports, but they don't tell you the heart and soul of the case.
You have to go back sometimes to the detective's original notes,
and you go back to his notebook that they took the day the case occurred.
And you get some of their thoughts and where they were headed with this case.
Yeah, this is one of the cases, like many, when we got it, it kind of had a built-in suspect, a white guy.
That guy, Michael Grotto.
He fit the description.
He was known to hang out at the Holiday Inn.
And he was eventually identified by a witness
as being there in the hotel that night.
So we thought, this guy's perfect.
And he had a long history.
He had a long criminal history of, you know,
forcible rapes and crimes like that.
Grotto goes to the top of the detective suspect list. He had a long criminal history of, you know, forcible rapes and crimes like that.
Grotto goes to the top of the detective suspect list. There is, however, a problem.
We found out he had committed suicide, you know, several years back.
So we were able to go back and we found some of the original hairs that the original detectives pulled from Grotto. So we resubmitted the hairs and they still had root follicles,
so they were able to do nuclear DNA on that hair.
Hoping for a DNA match and a quick resolution to the case,
cold case detectives send out the hairs to the crime lab.
The results come back as a shock.
Yeah, I called Detective Molesky and told him
that he was eliminated.
I think they were surprised.
We thought it would be Grotto.
Obviously it wasn't.
As for the white man
seen entering Mona's room,
cold case detectives suspect
the maid was simply mistaken.
No, I don't think there was ever a white man
let into Mona's room. I think she let a man
into another room.
It's back to the drawing board for cold
case detectives.
Took a turn, then it became a wide open
investigation. And that led
us eventually to Abney.
Abney is Wilbert
Abney, Mona's husband
and former murder suspect.
And it's clear that he had at least one girlfriend and may have been cultivating a second.
During the time that he was still married to Mona Lisa Abney, he had just bought a new
insurance policy on his wife.
Cold case detectives decide they would have word with Ebony and perhaps a swab of his DNA.
He's in Pennsylvania, a small town outside of Philadelphia.
He lived with his mother, who was an elderly woman, and he lived with his new wife.
On September 29th, cold case detectives find Wilbert Abney at home, living a quiet life.
That, however, is all about to change.
We knocked on his door and he answered immediately.
And Steve tells him what we're doing.
You know, we're cold case homicide detectives.
We're going to reinvestigate the murder of his wife from 28 years ago.
Typically, we expect to see a reaction of relief or someone that's actually glad that
we're doing this, thanking us for doing this. And we got exactly the opposite from Abney. His
reaction was, well, why would you do that? Why would you go back and work on a murder from 28
years ago? Some bells and whistles started going off in our heads. What an inappropriate reaction for somebody, you know, who's reinvestigating your wife's murder.
In 1978, Abney told police he had never been inside the hotel
where Mona was killed
and had not had sex with his wife in three weeks.
Cold case detectives ask for a sample of his DNA
to confirm the story.
He refused.
He said he didn't think he wanted to do that. At first, he said he wanted to call the story. He refused. He said he didn't think he wanted to do that.
At first, he said he wanted to call a lawyer.
Abney balks at providing the sample
until the current Mrs. Abney pulls her husband aside.
Well, Mrs. Abney stepped in, his current wife stepped in,
and said, can we talk in private?
And they're in the kitchen talking for a few minutes,
and I know what happened in that kitchen.
I know she told him, look, you had nothing to do with this.
You're innocent. Give him the buckle swabs and help him.
So the pressure really was on him at that point.
So he came back in and he said, okay, I'll give it to you.
Back at the crime lab, Mary Green begins the comparison.
I did the same DNA process on that swab,
and I was able to attain a DNA profile,
and it matched.
It was a very strong match.
The numbers were greater than the world population
or greater than 6 billion individuals.
The pieces of murder are starting to come together.
And it's clear that the original detectives
thought that Abney was involved.
They just couldn't put Abney in northern Virginia during the time that Mona was killed.
And that's what DNA gave us.
We had the scientific advantage that they never had.
DNA lays the foundation.
But cold case detectives need more.
In the Abney murder book, they find it.
A person no one has talked to in more than 25 years.
He reaches in his pocket and pulls out something
that looks like latex gloves,
rolls down the window and throws them out of the vehicle
over the railing into the river. I was shocked because I didn't think there was any such thing as cold cases.
That was just a TV show.
In January of 2005, a man named Michael Clark entertains a knock on his door.
On the other side, two homicide detectives,
looking for information about Clark's former neighbor, Wilbert Abney.
So we walk up to the door, knock on the door, and sure enough, he opens the door.
And he says, I'm Michael Clark.
And he said something to the effect, where have you guys been?
I've been waiting to talk to law enforcement for 20-some years now.
You think, man, you can't beat this.
Murphy and Malefsky are working the 1978 murder of Mona Lisa Abney.
DNA has linked her husband, Wilbert Abney, to the crime scene.
The phone rang early one Saturday morning. It was Abney.
He said to me, they have found Mona dead. Will you go with me to identify the body?
Well, he picks me up in this little white Corvette,
and he asked me to drive.
And I agreed to do that.
And before we got a mile from my home,
I had a very uncomfortable feeling. But what I remember distinctly was his
spending the life insurance proceeds from his wife's death. I remember specifically his talking
about buying 12 custom-tailored suits, about buying a new Rolls Royce and a big house.
Abney is saying, I'm going to be a rich man.
I've got all these life insurance policies.
I'm going to be rich.
My gut says, this guy smells.
There's something very, very wrong.
And I was very uncomfortable being in the vehicle with him.
You know, Mr. Clark said his mouth was just hanging open.
He couldn't believe that this man was talking about this.
Clearly it was not the demeanor of a man who just lost his wife.
At this point, we're about ready to enter the mouth of the boulevard bridge, going south to north.
Clark and Abney drive over the bridge on their way to ID the body.
When Wilbert Abney rolls down a window in the car.
We're approaching being over the water. Just as we got up to about this point, as soon as we got
over water, Abney rolled that window down, took out what appeared to be latex glove and tossed
him over that railing. If Abney is able to do this to his wife, then my family, I'm feeling that perhaps my family's being
threatened. If he's able to do that, what else is he capable of doing?
We just can't believe our good luck. We just can't believe that we stumbled into a witness
of this importance.
More than two months after taking Clark's statement, Goldcase detectives walk into Wilbert
Abney's house and begin to ask some
hard questions. So we go back and we sit in the living room and Steve tells him we got the DNA
results. And he just looked at us and Steve said, it's your DNA. He started lying. He started telling
us some things that we knew were not true. He's really a very narcissistic person. I think he
feels like he can control
the situation, he can manage it.
Abney denies killing his wife, but offers no explanation for the DNA match. Then he
agrees to a polygraph.
So from there, we went over to the local district attorney's office and he took the polygraph
and failed it miserably.
Cold case detectives return to Virginia and contemplate a possible murder charge against Abney.
Before they get too far, however, the phone rings.
Homicide, Detective Murphy.
Yes, Detective Murphy, this is Will Abney.
Wilbert, how you doing this morning?
Two days after failing his polygraph,
Wilbert Abney calls police.
What would be the most time I'd be looking at, in your estimate? Well, you know, the most time,
the absolute most time you could do is while he's in prison. Basically, he's saying, you know, look,
I'm not saying I did this, but if I did, what would I be charged with and how much time would
I get?" So it became kind of a cat and mouse thing with him, a negotiation, if you will.
Was it an accident? It could have been. I'm trying to understand.
During five separate phone calls, Abney fishes for information.
What would be the range on manslaughter?
I think one to ten manslaughter.
Say they gave me ten years, I'd have to do two and a half.
Under 1978 guidelines, I think it's something like that, yes.
This to me, this is a person that did this crime, and he's looking for a way to negotiate a resolution to it in his best interest.
He's trying to manage this whole situation, and it really goes to his arrogance that he thinks he can manage this situation.
Where would I do my time?
Well, somewhere in Virginia.
But there are a number of facilities in Virginia.
I mean, there's minimum security facilities.
I wouldn't get minimum security.
After a month of back and forth,
Abney tells detectives he's ready to tell his story.
What really happened that night at the Holiday Inn.
He said, I went there, I went to the hotel that night.
So now we're getting a totally different story that we haven't heard before.
I went into the room, we engaged in consensual intercourse,
and I choked her with my belt, which we did on occasion, that she asked me to do.
According to Abney, Mona liked rough sex and asked to be choked.
This time, however, she accidentally died.
There's the mark of the belt buckle on her neck.
I mean, that's how much force was used, was that there was a belt buckle mark left on her neck.
So clearly this wasn't an accident.
We had finally backed him into a corner where he realized he couldn't maneuver anymore,
and he had to come up with some kind of an explanation.
This is the only thing he could come up with.
Okay, I was there.
Okay, it is my DNA because we had consensual intercourse.
And yes, I did cause my wife's death, but it was an accident.
When detectives start asking questions,
Abney realizes he hasn't covered all his bases.
What about the fact that her credit cards were missing,
her ring was missing, her keys were missing,
her cash was missing.
You had things like that. What did he do with those things? And he'd forgotten about those.
And he just had that deer-in-the-headlights look, like, uh-oh, I didn't cover that one.
He was in the hot seat at that point. And, yeah, we had him. We had him.
56-year-old Wilbert Abney Jr., seen here last year,
will take the witness stand tomorrow in his first-degree murder trial.
Wilbert Abney never gets the deal he angled so hard for.
Instead, he is indicted for murder and faces a potential life stretch in prison.
He planned to kill his wife.
He did it for the insurance money,
and he did it because he had a girlfriend.
Katie Swart prosecutes the case against Wilbert Abney.
In this case, you had the DNA
that finally put this defendant, Mr. Abney,
in the hotel room back in 1978.
Because up to that point, he had denied being there, having sex
with her. He lied through his teeth back in 1978 that he hadn't been there, that he hadn't
had sex with her. And so he lied back then. Why do you lie? Because you're covering something
up.
At trial, Abney sticks to his story. Mona's death was an accident. He came up with the story
of the erotic sex where they were having this kinky sort of sex and it was an accidental
strangulation. The fact that in her back of the neck, you could see the belt buckle and it was
like that's not giving anybody pleasure to leave such an impression.
The jury doesn't buy Abney's story.
Unfortunately for Mr. Abney, he had told different stories, you know, at various points in this case. And then I think his credibility just didn't weigh much with the jury.
After four days of trial, he is found guilty and sentenced to 28 years in prison.
Everything came right back to me.
But it brought back quite a few memories and some pain and some of the heartache.
He needed to pay for this.
He took her life.
She was a young, beautiful woman
who had everything going for herself. And for her life to be taken like that, it's not fair, not right.
For cold case detectives, the verdict means one more case is closed. One more picture
can be taken off the wall. Unfortunately, too many faces remain, watching and waiting
for their day in court.
There's really no big celebration or big defining moment that ends the investigation.
It's just, okay, you've got all these others sitting here that need to be worked on,
you're demanding to be worked on.
Wilbert Abney filed an appeal in 2008.
It was denied.
And he was additionally denied parole.
His release date is scheduled for August 24, 2023.
He'll be 73 years old.
