As the days ticked by after Tanya and Jay's murder, with no leads panning out. Tangy his brother John despaired of ever finding an answer. It was a pretty, pretty dark time. I stayed home for a number of weeks, didn't go back to university for a while, tried to spend some more time at home with my parents and try to try to get through it, but it was very dark days. Despite a robust search for tips or witnesses by authorities, the days became months, and the months became years. There were 230 different people named as possible suspects in this case because it was profiled on unsolved mysteries back in 1980 9 or 88, so people from all over the country had been calling in tips on this. Every year that you don't get a hit, you know, it's like, are we ever going to get one? I was always hopeful that it would be solved. I never gave up hope knowing that a DNA evidence that was there. The DNA was the one thing investigators had going for them. But even as the national database known as codis expanded, they couldn't find an answer. I don't think they did any DNA work until like 1991 on this case. The DNA was put into codis and a year later it was put into the equivalent of codis in Canada. And there were no matches. I think a lot of people were surprised that it that there wasn't a match based on the profile of what the killer was expected to be like. Had the killer refined his approach to avoid leaving DNA again? Had he died? Had he left the country? It would take more than 30 years for law enforcement to find the answer. And it would come through genetic genealogy. This is the most powerful tool that's ever came along since DNA came along itself. Because it's a way that you can solve any crime if you have DNA evidence. Not just one where you've got a person that's encoded. In 2018, 31 years after tangy and Jay were murdered, detective Jim scharf received a message that would finally bring him closer to solving this cold case. I went to my office and I had an email from Barbara Rae Venter. And the email said, today they caught the Golden State killer and I don't want anybody to know it, but I was behind that. He was responsible for like 52 rapes and 13 murders in California over all this time period. And I thought, wow, this is great. Barbara ray Venter was a noted genealogist. She told me that she thought at that point she could help me. Identify the killer of Jay and Tanya. She says we need to get a DNA sample and upload it to Jed match, and we can work on identifying him through his relatives. And at that point, what was your understanding of jud match? It was a public database. If you get your DNA from ancestry dot com and I get my DNA profile from 23andMe and if you upload it to Jed match and I upload it to Jed match, we can match if we're related. So it's a way to match to more relatives. Jed match spelled GED match is a publicly open resource, which made it a potential boon for law enforcement trying to identify unknown DNA. As it turns out, Jim's team had already given a DNA sample of Tanya and Jay's killer to pair a bond nano labs. The company that was used in genetics to create composite sketches of suspects, like Raymond roe. Paraben agreed to do the Jed matched search for this case to see if they could identify the suspect that way. I'm thinking maybe we'll match to 40 relatives. Because I had put my DNA in to a couple of different companies, and I matched to like a thousand people. Most of them you're matching to fourth cousins. So you might have hundreds of fourth cousins out there that you have no idea who they could even be. Four days later, a pair of rep called him with an answer. He says, I've narrowed it down to one name. And I'm like, I don't believe this. What's the guy's name? And he says, William Earl Talbot the second. And I'm like, I have never heard of this person. Iran is criminal history. And it was pretty insignificant, I think he had a simple assault charge year or two before the murder. Nothing since then. Did that surprise you? Yeah. William talbott the second was a lifelong Washington resident who lived a nearby wooden ville and worked for a trucking company. He seemed unremarkable in every way. And he had never been on police's radar. Jim and his team now needed to verify Talbot's DNA. Detectives followed him down to a little cafe in Buckley. And he went inside and ate a lunch. We contacted the waitress and asked her not to throw his stuff away when she bust his table. So after he ate, they gathered the items that she had set aside in the kitchen. They packaged that and brought it to me. The results from the lab were definitive. Talbott was their guy. They were able to verify that it was him and the chance of it being anybody else is one in a 180 quadrillion. Were you excited were you nervous? Were you thrilled? I was like, I can't believe this. I feared up, like I am now. And then I said, we got him. And it was, it was just wonderful feeling. After all these years to solve such a horrendous crime like that. Officers cornered Talbot at his workplace, and Jim himself snapped the cuffs on him. I said, listen, you're under arrest and he says, what for? And I said, first degree murder. Now we're going to take you up to the sheriff's office and Everett. And we'll be able to talk. And he said, not after what you told me, I wanted to. I got on the phone and I called John kylan Borg. And I told him that he was in custody. He's sitting in the back seat of this car. And he's like, he's sitting in the back seat of the car you're in right now, and I'm like, yeah, he's all under control. You don't have to worry about it anymore. I've been a police officer for 44 years. And that day was probably the highlight of that whole career. Michael Lewis here host of against the rules..
