(Portland, OR) -- Authorities say a Portland man who's suspected of sexually assaulting a woman in the Springwater Corridor in Gresham was released from prison on parole last August. Officials say 50-year-old Thomas Peacock, who was convicted in 1989 for attempted murder, is accused of attacking a 22-year-old Portland woman who had stopped to change a flat bike tire on the path near Southwest Highland Drive. Police say Peacock was arrested yesterday near the Oaks Bottom Wildlife Refuge in southeast Portland. His bail is set at one-million dollars.
