A sex offender suspected of killing a Spokane woman who was working as a prostitute last August has been charged with murder.
Derrick Ross Vargas, 25, is to appear in Superior Court today on a first-degree murder charge for the brutal slaying of Evon M. Moore, 48, whose body was found in an alley near North Ralph Street and East Riverside Avenue Aug. 13.
Vargas was released from federal prison on Aug. 2 after serving about four years for having a sexual relationship with a 13-year-old girl when he was 19.
He's been in the Spokane County Jail since Sept. 23 after a Washington State Patrol trooper contacted him during a traffic stop and a woman jumped out of his truck and said she'd been raped.
Police say the woman was working as a prostitute on East Sprague Avenue when she met Vargas.
Police realized Vargas' truck matched a truck seen on the surveillance video near where Moore's body was found.
Detectives found a pair of shoes with blood on them in Vargas' East Trent Avenue apartment that matched the shoe tread pattern found near Moore's body. They also found a purse believed to belong to Moore, who was a student at Spokane Community College.
