The Cass County Drug Enforcement Team last week uncovered a comprehensive marijuana-growing operation in Penn Township.
Investigators on Wednesday searched a barn in the 16000 block of Dutch Settlement Road and surrounding property and uncovered the operation.
Detectives located numerous marijuana plants, more than five pounds of processed marijuana and a loaded firearm.
Officials said the estimated street value of the marijuana is $30,000.
Detectives arrested George Clifford Williams, 49. He was charged with manufacturing marijuana, possession of marijuana and two counts of felony firearms, sheriff’s officials said.
