Would really like to know what it was that led police to Deangelo. I understand they got DNA from his trash and now reading his car door handle, but still no info on how they came to surveil Deangelo. How many men of his age are living in California or the US for that matter and they just pick this one man??? Family or friend must have tipped off LE, I’m sure.
To Catch a Killer: A Fake Profile on a DNA Site and a Pristine Sample
“To find the DNA match, investigators created a fake profile, posing as a user who was researching family history. DNA information was uploaded into a genealogy site and a match was made with a relative. Investigators eventually zeroed in on the suspect and traced the DNA to Mr. DeAngelo’s front door.
It took about four months, from when the first possible links appeared on GEDmatch to when Mr. DeAngelo was arrested.”
I believe the match was to a 3rd or 4th cousin. They had to trace up that person’s tree to find the paternal ggg grand parents, then down the tree to find every possible male defendant that was a 3rd (or 4th) cousin to the matched dna. Could have been dozens. Then they had to look at each one of those people, to narrow down to their suspects. THEN they collected the discarded dna to see if it was the match to the GSK.
