The first case that gained publicity for being solved using genetic genealogy was the Golden State Killer case. In this case, the perpetrator committed at least 100 burglaries, 50 rapes and 13 murders between 1974 until 1986. I'm not sure this could be considered a cold case since the lead investigator never let up in trying to find the killer. The technique of using DNA triangulation along with family tree building of DNA matches found on GEDmatch.com led to the arrest of the murderer in 2018.
The other show is the one everyone is currently talking about. "The Genetic Detective" with Cece Moore on ABC. If you've ever seen Cece on any of the ABC News investigative shows or heard her on various genealogy podcasts, you'll know that she is a genealogist through and through. In each episode, you learn a little about Cece's family life and her story that led her to being the preeminent genetic crime investigator. A bit of the show can be accurately described as "reality television" in that it shows the character of Cece during her investigation. Based on these snippets, I can confidently call Cece, and I mean this in the most complimentary way, a "geek". Her quirky charm makes the show fun to watch, compared to Paul Holes' serious, by-the-book show.
In the end, I enjoy both of these shows enormously. I encourage you to watch them both.
These shows touch on each of our lives because they both, along with law enforcement organizations across the nation, now use genetic genealogy web sites, along with the matches found there, yes, even yours, to identify relatives of the matches to find the guilty parties. After initial controversy, these sites now allow you to opt-in, or at least opt-out, of law enforcement use of your DNA matches.
These investigators use the same techniques that I used, and many other genealogists use, to find the identity of the parents of adoptees. A cousin of mine commented after a recent genealogical discovery, that I should be a detective. I told him that I already am, both in my job and my hobby. He thought I should go into crime solving. While watching a recent episode of Cece's show, my wife suggested that I should call up the local police department and Parabon Nanolabs, which Cece works with, and tell them I can help investigate. Trust me, if I thought they'd consider me, I would. Sadly, it's not that easy. So I'll have to stick with genealogy as a hobby and I'm okay with that.
