A Tyngsborough man faces a pretrial hearing next month involving charges of cultivating a Class D substance, marijuana, and possession of the drug. Davis Street resident Frank Berry, 55, reportedly said marijuana and growing implements that were found in the basement of the house next door to his home were for personal medicinal use only. Berry told police that he is a paraplegic and that his wife, Patricia, suffers from multiple sclerosis. The house that allegedly contained the marijuana-growing operation is on land owned by Berry’s Grove Campground; police also reported a shed on the property being used to grow several plants. No charges have been filed against Patricia Berry .
