FREEHOLD - Authorities say new DNA analysis links a suspected serial killer to the death of a New Jersey high school student killed 50 years ago.
New Jersey State Police and the Monmouth County Prosecutor’s Office announced their findings Wednesday afternoon.
They say the new DNA information and other evidence links Robert Zarinsky to the September 1965 death of 18-year-old Mary Agnes Klinsky. Klinksky’s naked, battered body was found near the Garden State Parkway southbound entrance near what is now known as Exit 116.
An autopsy determined the Raritan High School senior had been sexually assaulted and died from multiple skull fractures caused by significant blunt force trauma. Evidence was collected, but technology at the time did not detect a DNA profile of a suspect.
Zarinsky was serving a life sentence for another teenage girl's killing when he died in prison in November 2008. At the time, he was about to stand trial for the 1968 murder of a 13-year-old girl.
Prosecutors say the DNA evidence excluded everyone but Zarinsky from being a suspect in the Klinsky killing.
