(Hillsboro, OR) -- After more than 30 years, an Oregon cold case is finally closed. A judge sentenced convicted murderer Robert Atrops to life in prison decades after the crime. The jury recently convicted him of killing his estranged wife Deborah. The murder took place in 1988. Robert reported her missing and she was found strangled to death in the trunk of a car in Beaverton about a month later. Atrops was arrested in 2023.
