David Silverstone’s Redwood Valley estate became the center of an investigation by the Mendocino County Sheriff drug task force, and on July 21, authorities seized 181 marijuana plants at the property, according to the New York Daily News. Silverstone, 43 was taken into custody and charged on two felony counts of marijuana cultivation and possession for sale. He was subsequently released on $25,000 bail. Silverstone followed in his younger sister’s footsteps in the 1990s when he worked on movie sets.
