A Louisiana grand jury indicted four KKK members Wednesday in connection with a Tulsa woman's killing.

Raymond Foster, 44, was indicted by a St. Tammany Parish grand jury on a second-degree murder charge in the November slaying of Cynthia Lynch, 43, of Tulsa.

Foster is thought to be a Ku Klux Klan imperial wizard and the leader of the group's Sons of Dixie Chapter. He is jailed with bail set at $500,000.

His son Shane Foster, 20, and Frank Stafford, 21, were indicted on charges of obstruction of justice. Danielle Jones, 23, was indicted on a count of accessory after the fact.

Shane Foster's bail is set at $250,000; bail for Stafford and Jones is set at $500,000.

Authorities believe that Lynch was recruited online by the Bogalusa, La.-based KKK group, then shot to death when she tried to leave an initiation ritual.
