Andrea Marin was 22 and a Portland State University student when she was found dead in her SW Park Avenue apartment in the fall of 1982. The last known contact with her was about 11:00 am on Monday, October 4. Her body was discovered by the building manager around noon on Friday, October 8 in the front room of the unit.

An autopsy determined blunt force trauma as the cause of death, and investigators established a timeline placing the killing before noon on Tuesday, October 5. Marin was known to both use and sell drugs, and her apartment saw frequent visitors; despite that, no clear suspect or definitive lead has emerged. No arrests have been announced and the case remains unsolved.

Did anyone who knew Andrea or spent time around the 1600 block of SW Park Avenue in October 1982 have information to share?
