LAKE WORTH, Fla. — A Lake Worth man's genealogy hobby has led to another arrest.

We told you in April about Curtis Rogers, the 80-year-old creator of GEDmatch, a database of DNA test results.

Now, CBS affiliate WKMG reports Orlando law enforcement officials were able to identify a suspect in the 2001 killing of a University of Central Florida student by first tracking down a relative via GEDmatch.

Benjamin Lee Holmes was later arrested after investigators compared DNA taken from one of his used cigars to semen found at the crime scene. Holmes has pleaded not guilty.

Rogers' DNA database gained national attention when it was central to locating Joseph James DeAngelo, the suspected Golden State Killer.

DeAngelo is accused of murdering 13 people and raping women while their husbands or boyfriends were nearby.

Rogers told 10Investigates he had heard of dozens of cases that had been solved with the help of GEDmatch.

"It is so heartwarming to get emails from people that have been affected," he said. "To me, it is helping these people that have been hurting for so long."
