SIOUX FALLS, S.D. (AP) – Federal officials have issued an arrest warrant for a Long Valley woman accused of beating a 32-year-old Wanblee man to death with a baseball bat.

Sharon McMillan faces a first-degree murder charge in Saturday's killing of Garland Morrison on the Pine Ridge Indian Reservation.

Oglala Sioux Tribe Police Chief Everett Little Whiteman said Wednesday that McMillan was initially jailed on tribal charges.

Court documents say a witness told an FBI agent that Morrison and McMillan and several others had been drinking throughout the day. The witness said they were sitting around McMillan's kitchen table when McMillan approached from behind and struck Morrison on the head.

McMillan told the agent that Morrison had first struck another person.
