The acquisition suggests that GEDmatch’s transformation from a popular genealogy site to a crime-fighting tool is almost complete.

GEDmatch launched in 2010 as an open-source database where individuals who have tested their DNA with private companies, like 23andme and AncestryDNA, could upload their results and find family members.

Most Americans first learned about GEDmatch in 2018, after law enforcement announced that they had used it to identify the suspected Golden State Killer.
