And it was obvious that there was a very brutal murder that had happened, a lot of blood. During the investigation, we came across a significant amount of DNA that we believe is from the killer. Would you say that this crime scene provided really good evidence? - Excellent evidence. - For nearly two decades, police could not find a match to the killer's DNA. So in 2014, they went way outside the box and searched a public DNA database, owned by ancestry.com. - It led us to this my cholessary junior. - Who just happened to be a film maker. - Films of homicide, kind of a murder mystery film maker. - Then he cuts off her head. - My name is Michael Usherie.

And she was young. - Got me the reputation of being a person who is really into murder and things like that. And I shoved your body over in the shower.
