Another genealogical cold-case murder solved.

From today’s Denver Post:

In what may be the first DNA genealogical cold-case murder solved in Colorado, a man who died seven years ago has been identified as a suspect who picked up an 18-year-old hitchhiker and bludgeoned her to death in August 1981.

Donald Steven Perea, who died in 2012, killed Jeannie Moore, 18, and dumped her body in 1981 in Genesee Park in Jefferson County, Jefferson County Sheriff Jeff Shrader said.

“While we would have preferred to place handcuffs on the suspect, we hope knowing who and where he is brings them some degree of closure,” Shrader said during a news conference at the sheriff’s office in Golden.

Investigators ultimately used a DNA sample provided by Perea’s daughter to confirm that he killed and sexually assaulted Moore.

“Further investigation led investigators to identify Perea as being 3.3 trillion times more likely than anyone else to have committed the murder,” Shrader said.
