A familial DNA search has led to an arrest in Virginia. Brad Jenkins with the Virginia Department of Forensic Science says several cases linked by DNA appeared to be the work of one person. He tells the Richmond Times-Dispatch that a familial DNA search found a possible relative of the suspect. The suspect was arrested following a police investigation and additional DNA testing. The newspaper says the department declined to provide any details at the request of local authorities. Familial searches use relatives’ genetic material to track suspects in violent crimes who have left DNA at a crime scene but their DNA isn’t in any database. In California, a familial search led to the 2010 arrest of a suspect in the “Grim Sleeper” slayings in the Los Angeles area.
