Suspect arrested in 1980 cold case homicide of teen woman

PORTLAND, Ore. (AP) — Gresham police identified a Troutdale man this week as the suspect in an 80s cold case homicide. The Oregonian/OregonLive reports police used DNA technology to identify 58-year-old Robert Plympton as a suspect in the killing of 19-year-old Barbara Mae Tucker. Gresham police on Tuesday arrested Plympton. Tucker was expected at a night class at Mt. Hood Community College on Jan. 15, 1980. A student found Tucker’s body the next day. The medical examiner determined Tucker had been sexually assaulted and beaten to death. It wasn’t immediately known if Plympton has a lawyer. He’s charged with murder, rape and sex abuse.
