Genetic genealogy, law enforcement’s new crime-solving lead, helps solve cold cases

By Patricio G. Balona, The Daytona Beach News-Journal

ORLANDO — Crime investigators call genetic genealogy a lead with DNA in it, a tool that can crack open decades-old homicide and rape cases.

That's because the science tracks family trees loaded with DNA available in public databases that police can use to identify the unknown source of DNA found at a crime scene.

And it's proving effective, as 70 cold cases have been solved in the country since law enforcement started using genetic genealogy 18 months ago, said Lori Napolitano, chief of forensics for the Florida Department of Law Enforcement in Orlando.

Also, the arrest of a South Florida man using genetic genealogy evidence has led to a break in the more than decade-old Daytona Beach serial killer case.
