US marshals looking for an attempted murder suspect found him and a marijuana grow operation at the same time.

Deputy US marshals arrested 33-year-old Marcus Williams at a home on Eldridge Road in Fountain City on Wednesday. He's wanted in Detroit for assault with the intent to murder, among other charges.

At the home where they arrested Williams, marshals also found a large number of marijuana plants.

Knox County authorities then arrested 25-year-old Dewayne Tolend, 24-year-old Demetrius Green and 27-year-old Ladonte Harris-Paige.

Williams is awaiting extradition to Michigan, and all four will face charges for the grow operation.
