Mayo bought, "on 11 occasions, hydroponic growing equipment that is specialized in indoor marijuana growing," according to sheriff's Detective Sgt. Todd Butler, who said local authorities received information from the High Intensity Drug Trafficking Area Program, a project of the Office of National Drug Control Policy.
"Operation Green Thumb has access to shipping invoices from suppliers who advertise their indoor marijuana-growing equipment in magazines such as 'High Times.' David Mayo bought his hydroponic equipment from one of the suppliers that do, in fact, advertise in this (manner)."
