LOS ANGELES — The executive director of a Northern California mental hospital has been arrested for allegedly molesting a foster child in his care for more than a decade. Napa State Hospital Director Claude Foulk was arrested Wednesday after a five-month investigation by Long Beach police. Prosecutors say there were numerous other victims but the statute of limitations prevents them from pursuing cases before 1988. The Los Angeles County district attorney's office says the 63-year-old Foulk is charged with 35 felony counts of lewd and lascivious acts with a child. Prosecutors say the crimes occurred in the Long Beach area between 1975 and 2006. Foulk was detained on the hospital grounds in Napa and is expected to be transported to Long Beach.
