PORTLAND — A Portland man indicted on dozens of sex-crime charges has pleaded not guilty. Thomas Oliver entered the pleas at his arraignment Friday and received a court-appointed attorney. Bail was set at $5.4 million. Portland police have not released many details about the case. Sgt. Pete Simpson said it involves six women or girls and they include sex trafficking victims, domestic relationships and friends of the 35-year-old man. A Multnomah County grand jury secretly indicted Oliver last month, and it was revealed Thursday.
