Low-flying helicopters seen around Bulloch and adjacent counties recently may be part of the effort by the Georgia Governor’s Drug Suppression Task Force to find plots of marijuana. Last week, the crew spotted a field of plants growing near Cobbtown in Candler County. Task force agents contacted the Candler County Sheriff’s Office, which responded and arrested Richard Anthony Warren, 61, of Cobbtown, on charges of manufacturing marijuana, said Candler County Sheriff John Miles.
