The state is seeking to have a former attendant at Rainier School in Buckley declared a sexually violent predator and civilly committed, court records show.

Clinton Paul McMunn, who was sentenced to more than seven years in prison in 2001 for sexually assaulting a client at the school for developmentally disabled adults, should be considered a repeat offender and a threat based on admissions he made during sex offender treatment, say documents state prosecutors filed Jan. 2 in Pierce County Superior Court.

McMunn, 34, was released from state prison recently and is being held in the Pierce County Jail pending a decision on his civil commitment. On Friday, a judge postponed for three weeks a hearing into whether there was probable cause for the proceedings against McMunn to continue. The hearing might be somewhat of a formality, though, since McMunn says he wants to be committed.

McMunn sent a letter to Attorney General Rob McKenna in April saying that.

“I have made it abundantly clear that I want to be civilly committed,” he wrote, according to the court records. “I know that I will re-offend if released to the public, and I wish not to make anymore victims.”

In August 2001, McMunn turned himself in to Buckley police and admitted to raping a 46-year-old patient with the mental capacity of a 19-month-old, the records say. He later pleaded guilty to reduced charges of taking indecent liberties by force and burglary with sexual motivation.

During sex offender treatment, however, McMunn reportedly admitted to more crimes, including abusing the same woman several other times, sexually abusing several other residents while helping them shower, and harming a woman at another facility where he’d worked.

“Beginning at age 6, he sexually abused several children and adolescents” including a close relative, court records say. “He estimated he had sexually abused 18-23 victims for which he has never been adjudicated.”

Under Washington law, the state can civilly commit those deemed to be sexually violent predators after they finish their criminal sentences in order to prevent them from re-offending.
