The woman called 9-1-1 at 4:43 p.m. to report that Caldwell, 63, was coughing and then unresponsive after a sex act. Washington County sheriff's officers and medical personnel responded and transported him to Providence St. Vincent Medical Center, where he later was pronounced dead. The woman told deputies she met Caldwell about a year ago at Portland Community College. Caldwell, she said, knew she didn't have much money, so he provided her cash for books and other things for school in exchange for sex acts at her apartment. Caldwell had not given her money Saturday, she told deputies. They decided against pursuing prostitution charges. Deputies notified Caldwell's family of his death Saturday evening. The Oregonian previously erroneously reported that Caldwell had been found in his parked car on Saturday.
