ALEXANDRIA, La. (AP) - Federal authorities say a leader and a member of a prison-based "whites only" gang have pleaded guilty in Alexandria, Louisiana, to being accessories after the fact in a 2016 slaying.

A U.S. Justice Department news release says 38-year-old Aryan Circle leader, David Wayne Williams of Sulphur, Louisiana, pleaded guilty Tuesday. Forty-three-year-old Leland Hamm of Tulsa, Oklahoma, pleaded guilty Wednesday.

In court records, prosecutors say both men were at a meeting where another Aryan Circle member, Clifton Hallmark, was shot after a fight broke out in Turkey Creek, Louisiana, in 2016. Jeremy Wade Jordan of Orange, Texas, faces a federal racketeering-related murder charge in the case.

Authorities say the Aryan Circle began in the Texas prison system and spread to rural and suburban areas in Texas, Louisiana, and Missouri.
