DNA website unaware of role in Golden State Killer investigation
SACRAMENTO, Calif. — A genealogical website that police used to track down a man they believe is the Golden State Killer says it had no idea its service was involved in the hunt for one of California’s most elusive serial killers.
GEDmatch said in a statement Friday on its website that it was never contacted by law enforcement or anyone else about the case or the DNA profile that was used.
The Florida-based company pools DNA profiles that people upload and share publicly.
GEDmatch says it has always informed users that its databases can be used for purposes other than genealogical research.
On Wednesday, authorities announced that a DNA match led them to arrest the Golden State Killer, who they identified as Joseph James DeAngelo, a 72-year-old former police officer.
A lead investigator on the Golden State Killer case told the San Jose Mercury News that authorities used GEDmatch to find a relative of suspect DeAngelo, who was arrested Tuesday.
Lead investigator Paul Holes said one of his team’s biggest tools was GEDMatch, the Florida-based website.
GEDMatch is a free site where users who have DNA profiles from commercial companies such as Ancestry.com and 23andMe can expand their search for relatives.
Major companies, such as 23andMe and Ancestry, do not allow law enforcement to access their genetic data unless they get a court order.
Holes says officials did not need a court order to access GEDMatch’s large database of genetic blueprints.
