Thomas Laverty, the local plumber convicted last year of using his business as a front for a large marijuana grow while collecting public assistance, was sentenced to 12 years in federal prison Tuesday.
Laverty, 40, was convicted by a federal jury in Worcester last January on allegations he and his father, Charles Laverty, used their Millbury plumbing business, Chuck Laverty & Son, as a front for a huge illegalĀ marijuana grow.
