Paula said she summoned the courage about a week later to tell police what had happened. They would soon tell her that they identified the man who attacked her. And it turns out he wasn't a police trainee. He was a 21-year-old salesman in Beaumont.

So when you looked at what had happened in 1981 with this sexual assault, you thought there's a lot here that seems awfully close to the Katherine Edwards case. I did. It turns out that the man who pleaded guilty in that 1981 case is a man by the name of Clayton Foreman. This is the same name that turned up in Tina and Shara's genealogy hunt.

He was one of two brothers from the family tree that they actually put together. And you might be wondering why his name never surfaced before. You have to remember that this case was back in 1981, and DNA collection wasn't even a thing by law enforcement. It was still a decade away. This is how he eluded detectives at the time.

As investigators get closer to solving this mystery, they begin to learn more about Clayton Forman's background. And in a twist in this case, one of the things they learned is that Clayton Forman, the suspect, actually went to the same school as Catherine Edwards, the woman who was killed. In fact, they probably walked down the same hallways here at school. And there was something else.

Catherine Edwards was actually friends with the suspect's first wife. In fact, Catherine Edwards was a bridesmaid at their wedding.

So you tell the FBI what you found, and they gather some trash at the suspect's home in Ohio.

So he'd been told that one of his Uber customers had had something taken and that he needed to come down. Maybe you guys could ask him a few questions about it. That's not what you were going to ask him?

So finally, 36 years after Katherine Edwards' murder and arrest, the team can now return to Texas to prepare for trial. And in South Carolina, another team of investigators, they're now chasing a promising lead in their case because of this new technology, the murder of Michigan mom Kathy Swartz, whose daughter has gone so many years without answers.

Investigators working the cold case murder of Kathy Schwartz, the young Michigan mother who was murdered, her baby right nearby, they had sent off the perpetrator's DNA taken from her pink phone to that lab in Texas, Othram. So after three decades with no arrests in this case, Othram actually uses their cutting edge technology to build a comprehensive DNA sequence of who the perpetrator is.
