(Durham, OR) -- The Washington County Sheriff's Office has closed the cold case investigation into a woman's murder in 1983. Police say 30-year-old Randy McEvers reported his wife's death as a suicide at their home in Durham. Investigators say evidence showed 28-year-old Nancy McEvers didn't kill herself. Randy McEvers gave police two different stories, but they didn't have enough evidence to charge him. The case was reopened last August, and investigators found new evidence. The District Attorney was reviewing the case when on February 8th, Randy McEvers killed himself. Investigators say the investigation into Nancy's murder is now closed.
