(Hillsboro, OR) -- A convicted rapist who's turning 18-years-old today will be transferred from the Oregon Youth Authority to the Washington County Sheriff's Office. Jaime Tinoco, who pleaded guilty to raping a woman outside Autzen Stadium last September after an Oregon game, is now accused of stabbing Nicole Laube to death outside Timber Creek apartments last August. Authorities say investigators discovered evidence linking Tinoco to the murder after he admitted to the rape. He pleaded not guilty to the murder during his arraignment yesterday.
