PORTLAND, Ore. (AP) – A convicted murderer who was executed by the state of Texas in 1999 has been identified via DNA as the person who killed a 20-year-old woman in Portland, Oregon, nearly 40 years ago.

Anna Marie Hlavka was slain in an apartment on July 24, 1979. Authorities said Thursday her killer, Jerry McFadden, was identified using the same technology that led to an arrest last year in California in the “Golden State Killer” case.

Hlavka was found sexually assaulted and strangled with an electric cord. The Portland Police Bureau said at a news conference retired detectives submitted evidence to the state crime lab in 2009 for forensic testing.

Authorities said that evidence eventually showed McFaddden, who was executed in Texas for the rape and killing of an 18-year-old high school cheerleader, was Hlavka’s killer.
