PINE BELT, Miss. (AP) — Eight Mississippi men are facing federal drug charges after a multi-year investigation led authorities to a drug trafficking organization with ties to California.

WDAM-TV reports that five of the men were arrested Tuesday morning while the other three suspects surrendered. The suspects pleaded not guilty during their initial appearance at the William M. Colmer Federal Courthouse in Hattiesburg on Wednesday.

The suspects include Dexter Jones, Darrion Jones, Mitchell Jones, Jamie Wheat, John Foster, Cedric Walker, Roderick Simpson and Derrick Coleman.

The men will have their detention hearing on Friday.

Mississippi Bureau of Narcotics Director John Dowdy says their main objective in the investigation was to take out the supplier in California.
