A sexually violent predator admitted violating terms of his release back into San Diego County, according to court documents unsealed Thursday.Matthew Hedge, 46, was taken into custody a week ago at his trailer near Donovan State Prison in Otay Mesa. Hedge was placed at the site in April following years of treatment at a state mental hospital.A hearing is scheduled Dec. 9 to determine whether Hedge will be revoked from outpatient supervision and returned to the mental hospital for further treatment.During a brief court hearing Thursday, Hedge's attorney, Marian Gaston, told Judge Michael Wellington that Hedge was not accused of committing any new crimes and has not had any thoughts of assaulting children.Hedge was arrested for not fully disclosing his actions -- pleasuring himself to women's volleyball on television and trying to pleasure himself to a photo of his female driver's legs, according to court documents -- to his treatment team, Gaston said.She said Hedge was fantasizing about adult women and not children, and that his treatment is working."Matt Hedge no longer fantasizes about children," Gaston told the judge.Liberty Healthcare, which manages Hedge's treatment program for the state Department of Mental Health, requested revocation of Hedge's outpatient status.Hedge was originally ordered into outpatient treatment in 2005, but his outpatient status was revoked within six weeks for violating terms of his release.After more than two years of in-patient hospital treatment, the court in October 2008 again granted Hedge's petition to be placed in outpatient treatment. He was ordered placed at the Otay Mesa site on April 13 of this year.Hedge pleaded guilty in 1989 to molesting four children in the San Diego area and served 12 years in prison. He was committed to the sexually violent predator treatment program in 1997.
