A Virginia businessman charged in a racketeering case targeting the Pagans Motorcycle Club pleaded guilty Monday and agreed to cooperate with prosecutors.

John N. Maggio says in his plea agreement that he conspired with the club's indicted national vice president and an unindicted co-conspirator to extort almost $30,000 from two business associates last year. Maggio pleaded guilty to the charge before U.S. District Judge Thomas Johnston in Charleston. He faces up to 20 years in prison.

Maggio is one of 55 Pagans members and associates from West Virginia, Kentucky, Virginia, Pennsylvania, New York, New Jersey, Delaware and Florida charged in the case, which centers on murder conspiracy, kidnapping and other charges.

Maggio, a 47-year-old electrical contractor from Alexandria, Va., says the alleged plot began when he contacted Pagans vice president Floyd "Diamond Jesse" Moore for help collecting unpaid business debts. Maggio claims he's known Moore -- a former electrician himself -- for more than 20 years and knew he was a ranking Pagans leader.

According to the document, Maggio was recorded telling an associate of Moore's how to find the extortion victims, what they look like and that he did not care how badly they might be injured.

Moore has pleaded not guilty to numerous charges, including racketeering, murder conspiracy and threatening witnesses. His attorney did not immediately respond to a call seeking comment.
