Dateline: Missing In America - The Cold Case of Nancy Snow

Episode Date: July 8, 2025

On November 4, 1980, 44-year-old Nancy Snow boarded a flight to Baltimore from St. Louis, Missouri, where she had spent several months working on Gene McNary’s U.S. Senate campaign. That night she went to a party in Baltimore; the next morning she had breakfast with the party’s host. Afterward, a man who was housesitting for Nancy apparently picked her up at a hotel, and they drove off together. Nancy Snow hasn’t been seen or heard from since then, and her disappearance is one of the D.C. area’s oldest unsolved cases. More than 44 years later, her three daughters are convinced they know who is responsible for Nancy’s disappearance.  Dateline’s Josh Mankiewicz talks with her daughters Justine, Kimberly and Stacy Snow, Corporal William Noel of the Annapolis Police Department, and retired detective David Cordle. If you have any information about the disappearance of Nancy Snow, please call the Annapolis Police Department at 410-268-9000 and ask for Corporal William Noel.

November 4th, 1980 was an election that changed America. The polls were still open on the West Coast when NBC's John Chancellor called the race. Reagan is our projected winner, Ronald Wilson Reagan of California. There he is, the president-elect. Across the country, Republicans were toasting their win. In Baltimore, Maryland, 44-year-old Nancy Snow was celebrating at a victory party. Occasions like this were her sweet spot. Kimberly, Justine, and Stacey Snow are her daughters.

She was just so full of light. She was so amazing. She always made you feel like you were the most important person in the room. Those memories of their mother are vivid. They are also frozen in time because not long after that party ended, Nancy Snow vanished. I have been obsessed my entire life with finding my mom. You go down these rabbit holes and you spend years just researching, researching, researching.

This kind of takes over your life, doesn't it? Oh, absolutely. Nancy's missing persons case is one of the oldest and maybe the coldest at the Annapolis Police Department and her daughters cannot understand why. It seemed too obvious that something happened. Why couldn't they solve it? They are convinced they know who is responsible for their mother's disappearance. The detective assigned to Nancy's case has his eye on someone too. He's still alive. So to me, no one's gotten away with anything until they're unavailable

for prosecution. To tell Nancy's story, we had to reach back into the distant past. And that's where things got unexpectedly personal for me. I had a strong sense when I heard her name that I had met your mom. Wow. People talk a lot about six degrees of separation. It turned out there are fewer than that between Nancy Snow and myself. I'm Josh Mankiewicz and this is Missing in America, a podcast from Dateline. This episode is the cold case of Nancy Snow. Please listen closely because you or someone

you know may have information that could help Nancy Snow's family find the answers they're still looking for. In her daughter's memories, Nancy Snow is a young and vibrant mother whose energy was boundless. She was fearless and she was really funny. That's Kimberly, the baby of the family. And Justine is the middle sister. She loved adventure.

She loved travel. Stacey is the oldest. My mom not only spoke English and French, but she knew German, she knew Portuguese, Spanish, Greek, Italian, and she knew some Russian because part of my dad's job was to deal with Russian dignitaries back in the day. Their father, Bob Snow, was an Army intelligence officer who also worked in the Foreign Service. His career took the family across the globe, and Nancy relished her life abroad. She shared the family's exploits with relatives back in the states.

It was the era of letters, postcards and cassette tapes. I thought rather than try to write to you tonight, I'd make you one of these quick tapes. In the spring of 1973, Nancy sent her father this recording from Berlin. I've never seen a big city so full of parks and trees and gardens and flowers and it is just breathtakingly beautiful. By early fall 1974, the snows had moved back to the states and settled in Carmel, California. Nancy got involved in local politics and worked for the March of Dimes. Justine says her mom was always volunteering for something. Sand castle contest, pumpkin carving contest, field trips.

She was volunteering and she was bringing you along. She was bringing us along. Life was full and busy, but beneath the surface, Nancy was restless. In 1978, she and Bob separated, and Nancy moved into a condo in downtown Carmel. It was so devastating for me. It was the first heartbreak of my entire life.

About a year later, Nancy shook things up once more. She announced she was moving to Annapolis, Maryland. What did she say about moving to the East Coast? Why'd she wanna do that? Politics. She wanted to get into politics. At big time. She began working for the Republican National Committee,

traveling and making connections in the big leagues of national politics. In June 1980, her divorce became final. And later that summer, Nancy moved to an apartment at 91 East Street in downtown Annapolis. It was close to the harbor and she enlisted a man named Paul Collins to help her with the move.

They dated casually and stayed friends. It was a scramble because the RNC was sending Nancy to Missouri to work on candidate Jean McNary's Senate campaign. She would be based in St. Louis for two months, and Paul was going to house sit for her. She asked him if he could just please just, you know, watch over the apartment, just make sure everything's okay, doesn't get broken into. Nancy sent a steady stream of letters and postcards to all three of her daughters while she was in St. Louis. Her tone in those dispatches is loving and playful.

Her paragraphs are sprinkled with smiley faces and exclamation points. Here's Kimberly describing a postcard she received. She complimented my ninth grade photo from school. She said it was merely fantastic, all in caps, and noted that I was smiling in it and said a first, I think. Her daughters, who were by then 14, 15, and 19 years old, were happy. And so was she Because right around then is when some kind of romantic lightning struck Nancy Snow In a letter Nancy wrote to Stacey in September 1980. She shared this piece of news quote I must tell you I am deliriously in love with a big-time political TV producer from Baltimore

Probably won't last, but for the moment, we're bonkers. Neat." Election Day 1980 drew closer, meaning Nancy would soon face some choices. When the McNary for Senate campaign ended, she would be out of a job. What would she do next? What would become of her relationship with that new man? And would she stay in Annapolis? Nancy told her daughters she was sure about this.

She wanted to get out of politics and try something different, like working and living on the water. She said, I'm just going to start a charter business. I'm going to run the show. I'm going to take people to the islands and I'm going to live a peaceful life. She actually told me that. Financially, Nancy was in a position to make some big choices. Her father's recent death had given her an inheritance. Plus, she had money from the divorce. Nancy seemed serious about this change of course.

In a letter to Kimberly, she mentioned a job prospect on a boat as a cook. Kimberly read me an excerpt. Paul seems to think I have the boat cook job in my pocket. It's a 52 foot swan, a big boat. It's supposed to go between Fort Lauderdale and the islands. I don't know if I'll take it or not. Part of her hesitation may have involved Stacey, who was set on going to the University of Maryland for college, and she was going to live with Nancy. She planned to come to Annapolis after Nancy returned from St. Louis. Let's recap the Senate races,

which we've been able to project so far tonight. First of all, on November 4th, election day, Nancy's candidate, Gene McNary, was losing his Senate race, but Republicans were on the verge of a big win nationally. Nancy's family says she called them in Carmel before she left St. Louis and told them she was going to a political event that night in Baltimore and would call again when she came home to Annapolis the next day. On November 5th, Nancy did not call again, as she had promised.

A couple more days went by and there was still no word from her. Now, in 1980, cell phones barely existed, and it was not unusual for people to go days without calling, unless you were Nancy Snow. Justine urged her father to check with Nancy's house sitter, Paul Collins. Maybe he knew where she was. So my dad did call and talk to Paul Collins. And he said that my mom had gone on this boat trip and she'll be home by Christmas. Justine says Paul told her father not to worry because Nancy was sailing with friends of a friend. Christmas came and went and

Nancy had not returned. Stacy went ahead with her plans to fly to Maryland. She arrived two days after Christmas and Paul picked her up from the airport. When they got to Nancy's apartment, Stacy expected him to hand over the keys, but she says he did not. He goes, no, no, I stay here. I'm watching the house. And I'm like, what? He goes, yeah, I sleep in your mom's room.

And I'm like, what? Stacey had just met Paul for the first time at the airport. She was not happy with the arrangement, but felt she did not really have a choice. A few more days went by with no sign of Nancy, and by now, Stacey was really worried. So Paul said he'd alert the Coast Guard to keep an eye out for Nancy. And then he suggested they take a road trip to look for Nancy themselves. He heard that if we go down to Fort Lauderdale, where he thinks mom got on a boat, we could talk to the Fort Lauderdale police.

He goes, so let's drive down there and let's check it out. Paul and Stacey piled into Nancy's turquoise Volkswagen Beetle and drove through the night down I-95 to Fort Lauderdale. When they got there, more than 16 hours later, Paul went to the police station to file a missing persons report. Stacy walked around town showing people photos of Nancy and asking if they'd seen her.

No one had. A few days later, they drove back to Maryland. Stacy says a few of Paul's friends were hanging around the apartment. And that made her uncomfortable. They would come over and they would be smoking pot. They would be doing stuff and that that's not my thing. Stacy decided to go back to California. She says Paul told her he had also filed a missing persons report with the Annapolis police, which meant two police departments in two

states would be on the lookout for Nancy. Soon the search for Nancy Snow would shift to international waters and become a quest to find another person, a mysterious character known as Captain J. Let's talk about the Captain J story. Okay. Anybody ever speak with him? The answer to that question is complicated. April 1981, Nancy Snow's family had not heard from her for more than five months. By then her daughters were certain she was not on a boat trip in the Caribbean. Because deep in their bones, they knew their mother would absolutely have told them

all about it. She would let us know. She always kept us informed. All three daughters knew how much Nancy was looking forward to Stacey coming to live with her in Annapolis. She talked me into moving out there and going to college there instead of California. Why would she just then just go poof, you know?

At the very least, Stacey, she would have said to you, hey, plans have changed, I've taken this boat job. Exactly. With her mother missing, Stacey scrapped her plans to attend the University of Maryland. Now she faced the task of moving Nancy's belongings back to California. Stacey's godfather, a family friend who lived in Washington, D.C., was going to help her pack up the apartment. As they were making their plans, Nancy's house sitter Paul Collins phoned with some bad news. Paul called my father and me and said,

oh, you don't need to come out because I hate to tell you this. It was a terrible flood, and your mom lost everything. To Stacey, that made zero sense. Nancy's apartment was on the third floor of a brownstone, and there were no reports of a biblical-level flood in Annapolis. Of course, it was possible a water pipe had burst, but Paul had not said that. And to Stacy and her father, the timing of the call seemed suspicious. So Stacy called the Annapolis police, and that is when she learned something that stunned her. It turned out

Paul Collins had not reported Nancy missing to local police back in January after they'd returned from Fort Lauderdale. You took his word for it. Yeah, I mean you're 18, you know, you're expecting adults to do the right thing. Stacey had barely absorbed this news when she got a call that sent off more alarm bells. A friend in Annapolis said she'd seen someone driving Nancy's car and had spotted friends of Paul Collins wearing Nancy's clothes. Stacy got on a plane and headed to Maryland. By then, Paul Collins had filed a missing persons report with Annapolis police,

but only two days before Stacey arrived on the East Coast and five and a half months after Nancy's disappearance. In that document, Collins told police he had reported Nancy missing in Fort Lauderdale in January and did not know he needed to file another report with Annapolis authorities. By that time, Paul had moved out of Nancy's apartment on East Street. Stacey says when she and her godfather went there to check on Nancy's belongings, police came with them.

The landlord unlocked the door. So the police had me stand in the hallway and they came in first. After the officers checked out the apartment, Stacey walked in and her heart sank. There was nothing there. Stacey says her mother's clothes and furniture were gone. So were the belongings Stacy had shipped

from California for college. Other than a small amount of food in the refrigerator, the apartment was empty. There was no sign of that flood Paul had mentioned either. So why were Nancy's belongings missing? And where were they? Stacy says she and her godfather, along with police, tracked down some of the people

who had her mother's possessions, which Paul Collins had apparently given away. At one point, they visited a woman who was a friend of Paul's, and who, when she opened the door to Stacy, was wearing Nancy's nightgown. She was wearing my mother's nightgown. My mother's nightgown.

And we go upstairs, and they're eating off my mother's plates. They're watching TV on my mother's TV. They're sleeping on my mother's bed. None of that supported the story that Nancy had left on a boat adventure and was planning to return in late December. It was quite the opposite. Everything Stacey had seen and heard only deepened her gut feeling that something terrible had happened to her mother.

Police wanted to ask Paul Collins more questions, but according to the case file, they had trouble locating him in the months after he filed that report in Annapolis. WJLA Washington. That station ID was part of the soundtrack of my life in April 1981. Right around when Annapolis police were first learning that Nancy Snow was missing, I was a very green TV reporter at WJLA Channel 7 in Washington, D.C., about 35 miles from

Annapolis. I don't remember if I did stories about Nancy's case, but it is the kind of thing we covered, which could explain why all these years later, when we at Dateline decided to feature Nancy's story in Missing in America, Nancy's name and face seemed familiar to me. There is another possible explanation. Before I went to WJLA, I was an off-air reporter for ABC News, assigned to national politics.

I very closely covered the 1980 campaign, especially the congressional and Senate races. As I told Nancy's daughters, given their mother's work in politics, it is quite possible, maybe even likely, that Nancy Snow and I crossed paths. I had a strong sense when I heard her name that I had met your mom at some point. Wow. Now, I'm not telling you that I remember meeting her or that we were friends

or that I can tell you what the interaction was, but we were absolutely in the same circles that year. Someone I definitely did not encounter back then is Corporal William Noel. When Nancy Snow went missing, he was three years old. Today, he's the Annapolis police detective working to solve her case. He's gone through the case file, including the missing persons report Paul Collins made in April 1981. So early part of November 1980 we have Nancy returning from all accounts a pretty grueling stretch of campaign work. You're convinced that was

her on the plane. She flew from St. Louis to Baltimore. Yes, I'm convinced. Piecing together Nancy's movements after she left the airport was a challenge for Annapolis police, especially because by the time Paul Collins reported Nancy missing to them, the trail was more than five months old. All of the sort of traditional avenues of investigation that we think of first today when we're trying to find somebody or figure out where they were, you know, tracking their phone, getting their emails off their computer, doorbell cameras, license plate readers, security video at the airport. None of that existed.

Zero. And the lack of a footprint for such a busy woman is, in today's terms, just unthinkable. But it was the norm. There are conflicting accounts of when Nancy returned to Maryland from Missouri. However, our reporting points to her being in the Baltimore area on election night. In his April 1981 Missing Persons Report, Paul Collins told police when Nancy returned to Maryland on November 4th,

she stayed with a friend named Bobby at a, quote, fancy hotel near Towson, unquote. Towson is a suburb of Baltimore, and Bobby was Bobby Goodman, the political TV producer Nancy had written about to Stacey. He's the man Nancy said she was deliriously in love with, the same man who hosted the party she went to on election night. He's also someone I knew back when I was a political reporter. Back in the 70s and 80s, Bobby Goodman was a very big deal in the world of political

campaigning and advertising. His son was my college classmate, so I knew him too. Police knew Bobby Goodman played some part in Nancy Snow's last recorded days. The question was what part and whether he wanted to talk about it. Was the boyfriend married at the time? I believe there's indication that he may have been. According to the April, 1981 statement, Paul Collins gave police,

Nancy asked him to meet her on November 5th at that fancy hotel where she was staying. Paul told the detective he did not remember its name. Paul says he waits for her in the lobby and he sees her possibly traveling in a green BMW and a gentleman driving that BMW and at which point Nancy gets out of that car and joins Paul for the return trip back to Annapolis. Corporal Noel says the original case detectives interviewed Nancy's boyfriend, Bobby Goodman, who corroborated

parts of the story told by Paul Collins. And he was helpful. Yeah, he was helpful. The detectives at the time, they were satisfied. Paul told police that after picking up Nancy, they stayed at her apartment in Annapolis for a couple of days. Then he said something significant happened on November 8th in the middle of the night. According to Paul, Nancy had

gone to a local bar a couple of blocks from her apartment. At 3.30 a.m. she came home and said she was going to drive in a van to Fort Lauderdale with a boat captain she had met that night. His name was Jay, and they would be transporting boats between islands in the Caribbean and Fort Lauderdale. Paul said Nancy's plan was to return sometime between December 17th and December 27th. Remember, he told Nancy's family she would be back by Christmas. Paul said she packed some clothes, they had some coffee, and then he walked her to the corner of East and Fleet Streets, near her apartment. The report does not mention if Paul saw Nancy drive away. Noelle says police started looking

for the mysterious Captain Jay. Their search stretched from Maryland to the Caribbean. Law enforcement in Fort Lauderdale assisted. The Annapolis Police Department called in anyone they could given our proximity to the Naval Academy. They used resources to call Coast Guard, Naval records, anyone that may have set foot on a ship or vessel with the name or nickname J. And it sounds as if one investigator was on to something.

A police report filed in Fort Lauderdale, May 6th, 1981, notes that one Annapolis detective believed Captain Jay was actually a man he said had been the subject of a drug investigation by the DEA. Is it in the files whether he was ever spoken to and whether he acknowledged knowing Nancy? So I didn't see any interview or any contact being made with him. Back in 1981 even as the hunt for Captain J continued,

investigators kept their focus on Paul Collins and something he said in that missing persons report caught their eye. He had told police he and Nancy were close friends and casual lovers, who at one point had dated for about six months. Police wondered if their relationship might have been more complicated than Paul described. Justine met Paul while she was with her mom in Annapolis. He was 15 years younger than Nancy, and Justine did not think he was her mother's type. And I was like, what is your attraction to this guy?

And she's like, well, I'm not attracted to him. It's just that he's helpful. You know, he's a handyman, and he's easy because I don't have to think too hard when I talk to him. Those were her exact words. Okay, but there was clearly a time when they were, I don't know, involved might not be the right word, but seeing each other, dating, something was going on. I think they were casual drinking buddies. Stacey had a different impression.

My takeaway with Paul is that my mother was kind of enamored with the fact that a younger man was schmoozing her and she had a weakness that way with men outside my dad and she didn't make some good choices after my dad. In that April 1981 missing persons report, Paul told police Stacy gave him permission to put most of Nancy's belongings in storage and to sell some items to pay off her debts. Stacy says that is not true.

Police subpoenaed Nancy's bank records and discovered Paul was writing checks on her account. Corporal Noelle says, from a law enforcement standpoint, the fact that Paul was Nancy's house sitter complicated the picture. Paul maintained that he had that permission to pay her bills, give himself a quick stipend as needed. The issue is we have nobody to refute it

because Nancy's missing, and we don't have any way to confirm with her that those things were true or not. You're convinced that Paul Collins was continuing to pay Nancy's bills after she disappeared? We have records of some of the canceled checks where he did pay some bills. Corporal Noel says Paul Collins did not have access to all of Nancy's accounts and he was not withdrawing huge sums of money at a time from her checking account. Maybe once a month, once every other month there was an amount drawn to him. He never withdrew an amount that would say, okay, he's taken off or he's trying to clean out her account.

One of the things Mr. Collins apparently told Nancy Snow's daughters was that there had been a flood in her apartment building and a lot of her stuff got ruined and he had to throw it out. Yes. Was there a flood in her building? We've not been able to corroborate whether a flood occurred or didn't. He's told conflicting stories about when he reported her missing. He's given away her possessions. He's writing checks on her account.

That's not enough to arrest somebody. The state's attorney couldn't persuade a jury. That's a separate conversation. In the investigative world, circumstantial is great. It lets you know you're on the right path. But in terms of handing that baton off to the prosecutor, they have a set of needs that they have to have kind of lined up before they say, Hey, we'll bring this to a grand jury.

Nancy's family tried to keep on living their lives. Stacey returned to California with the belongings she recovered from Paul's friends, and then joined her sisters who'd moved overseas with their father, stepmother, and step siblings. Bob Snow, Nancy's ex-husband, had a new job in Germany. You all came to believe that whatever had happened she wasn't alive anymore. Of course. She would never not call us. Nancy's teenage daughters remained determined to find out the truth about her disappearance. They just had no idea how long that quest would last.

Nancy's case file stayed open and someone besides Paul Collins stayed on the law enforcement radar. A detective at the county prosecutor's office would be paying another visit to Nancy's boyfriend, Bobby Goodman. You spoke with him. Yes, I did. Cooperative? Cooperative in the sense that he was very very careful with his thoughts and his words. In 1988 Nancy Snow was legally declared dead, and a year later, at the urging of her daughters,

Nancy's case was reclassified as a homicide. David Cordell of the Anne Arundel County State's Attorney's Office caught it, and during the nearly 30 years Cordell worked Nancy's case, he chased hundreds of leads and re-interviewed dozens of witnesses. One of those interviews was with Bobby Goodman, Nancy's new boyfriend at the time of her disappearance. And as far as police can tell, one of the last two people to see her alive. You spoke with him. Yes, I did. Cooperative?

Cooperative in the sense that he was very, very careful with his thoughts and his words. We interviewed him at his home and his wife was present, so I had to make sure that we were kind of segregated from her, but I think that may have had something to do with his reluctance. But overall, he was cooperative. Cordell says Goodman's wife was briefly inside the house while the two men talked outside on a patio about the evening of November 4th, 1980 and the next day. He confirmed that he was having an affair with Nancy.

Yes, but maybe not to the extent that Nancy was perceiving it. He spent the night with Nancy? From the original reports and stories from witnesses, yes. And they had breakfast together the next morning? That's correct. Then he reports Nancy getting in a car with Paul Collins? He couldn't identify who she got into a car with

because he did not know who it was. He just saw a male subject with Nancy getting into this car and driving off, and that's the last that the witness says he saw of her. Of course, Cordell says he was eager to interview Paul Collins, too, but unlike Goodman, Paul was not cooperating. I think I spoke briefly with him on the phone. Anything else, he chose not to talk with us. Numerous attempts had been made.

In 2005, Paul Collins was subpoenaed to appear before a grand jury. At that proceeding, he took the fifth. He got an attorney and he didn't speak with you and he wouldn't speak with the grand jury Correct four years later. Collins did agree to speak with a detective and a prosecutor under a use immunity deal Meaning anything he told them could not be used against him But he could still be charged if they found other evidence to connect him to Nancy's murder. With his attorney present, Collins sat for a two-hour interview, which was not recorded.

According to a written summary by the detective who conducted the interview, Collins gave a brand new account of his interactions with Nancy. The detective wrote, quote, I asked Paul Collins to tell me what he remembers about picking Nancy Snow up when she returned from Missouri. He advised that his memory is that he picked her up at BWI Airport arrivals. I told Paul Collins that he had previously said that he picked Nancy Snow up at a hotel in Towson, and that he saw her get out of a car. I further told him that he had previously told us the make and color of said car. Paul Collins advised that he does not remember any of that, and

that in his memory he picked her up at BWI Airport." According to the detective, Collins also said Nancy returned from St. Louis one or two days after the 1980 election, not on election day, as he had told the police in his original missing persons report. Over the years, Stacey, Justine, and Kimberly have spent countless hours replaying what they say Paul Collins told their father about a boat trip back in November 1980, when they had not heard from Nancy for days.

He was trying to make it sound like my mom went off with friends, not strangers, so that we wouldn't worry. Like that was his first contact with my dad. That is what Nancy's family says Paul Collins first told them. But more than five and a half months later, Paul told police a different story. That version had Nancy running off with the elusive Captain J, not with friends. He made it clear that he did not know who these people were, that he did not know this Captain J. He told investigators he knew nothing about it until that night when my mom told him.

Corporal William Noel, the Annapolis detective now trying to solve Nancy's case, does not believe this 44-year-old mystery has anything to do with a Captain J. You don't think Nancy ever went to sea? You don't think Nancy ever got on a boat? You don't think she made it out of Annapolis? No, tall. You think she died the day that Paul Collins picked her up? the day that Paul Collins picked her up? I believe that whatever happened, Nancy Snow happened very soon after she was picked up from that hotel in the Baltimore area. Bobby Goodman died in 2018, leaving investigators without one of their key witnesses. Is or was the boyfriend ever a suspect? The investigators reporting from anything I've seen at the time never

indicated him as a firm suspect. The only person that drew the raised eyebrow of anybody that investigated this case is Mr. Collins. Corporal Noel wanted to sort through all those inconsistencies in Paul Collins stories, among other things. And in March 2021, Paul Collins agreed to talk with Noelle by phone. Tell me about that call.

It was brief, but Paul struck me as somebody who is very familiar with how investigations go. I want to say he was cooperative in so much that it served him and then when we get to the nuts and bolts of are you available to speak with me, he advised me that he wouldn't be doing that and that he wished her family, her daughters, nothing but the best and that if I could to offer them some words of comfort and I told him I wouldn't do that. I could set up a call but I wouldn't do that on his behalf and that pretty much ended our conversation. Paul Collins remains a person of interest?

Absolutely. But not a suspect? Can't call him a suspect yet but I will say that he's a person of interest. Nearly a suspect, but I can't say that he's a suspect because right now we're circumstantial. I don't have my PC yet. By PC, he means probable cause. To build a criminal case, detectives and prosecutors need to establish evidence that a crime was committed.

If Paul Collins killed Nancy Snow, what was the motive? Tough to theorize that out in the open, but it's not unknown that Paul was romantically fond of Nancy. It's unclear what the nature of their relationship was after an initial courting of Nancy by Paul. And from all indications, Nancy saw him as basically a nice guy, but not a guy she wanted to have a relationship with.

And very clearly, it seems she was much more interested in the guy in Baltimore. Yes. The man she met at the hotel. Correct. So maybe Paul Collins is angry that she's not interested in him, or maybe Paul Collins is angry that she's not interested in him, or maybe Paul Collins

wants to get his hands on the money that Nancy has recently inherited? There's a possibility of some jealousy that he's not the main guy in her life. It could be a financial desire on his part. The issue for me as an investigator is getting in front of Paul Collins in a setting where he would even talk to me about it, and that's where we've run into a pretty big brick wall. Paul Collins has never been arrested or charged with anything connected to Nancy Snow's disappearance. He is now 74 years old and living near Washington, D.C. We reached out to him and he has not responded to our requests for comment.

Do you think you're going to eventually solve the disappearance of Nancy Snow? You know, I really would like to deliver that for her family and for Nancy. I think I've got enough years left at the agency to see it through. Any cold case detective will tell you this. Time is both their enemy and their friend. With every passing year, evidence can get lost, witnesses can die, memories can fade. And also over time, witnesses and sometimes even perpetrators can change in unexpected ways. David Cordell, who labored over Nancy's case for almost three decades, knows that firsthand. I've seen it before. Over periods of time, relationships change.

People grow up, people grow old, people get religion, people want to get things off their chest. And sometimes, the alibi I gave you X number of years ago, I'm no longer going to lie for you. Absolutely. That's what you're hoping for here. Absolutely. As the years passed, all of Nancy Snow's daughters got married and became mothers themselves.

Today, their own mother would be 88 years old, making it 44 years since any of them have heard her say their names. All they have now are those cassette tapes Nancy left behind. I was concerned about Justine and Kimberly not being, you know, strong swimmers yet. So I have a young man who's a lifeguard at the pool working with some three times a week. Kimberly in one lesson has learned to swim and Justine is coming right along too. We're so pleased with both of them. Now Stacey already knows how to swim and she's going off the board and doing all kinds

of tricks and things. She would sing me to sleep. She would read me stories and I think maybe most of all I really miss that voice. Sorry. I think what my sisters don't realize is when I listen to them talk, when I don't see them and I listen to them, they sound like my mom. I hear her through some of their mannerisms and what they say and how they say it and their intonations. I can hear it. Your mom wouldn't have wanted this to take over your life. No, I don't think so. That's why I tried to change and become the mother that she was to me for my kids

and pour my love and my heart and my time into them and mold them to be like my mom because she was so amazing. And I have her pictures all over the house and I tell stories all the time. And I wanted to pass on her spirit to others. Like her sister, Stacey, Kimberly holds on to the things her mother gave her that can't be taken away. She just believed that I was extraordinary and that I was capable

of anything. So I think of all the things that she taught me, I think the most powerful is how to believe in myself and how to love myself and how to be present in the moment and to soak in the life around me. We let Justine have the final word because what she told us goes for her sisters too. I want justice to be served. I want to know the truth. I will never stop looking for our mom.
