Rios arraigned for murder charges for 1975 killing of Aquash

Rapid City, South Dakota (AP) 10-09

A Rapid City woman pleaded not guilty to murder charges filed in a 1975 shooting death on the Pine Ridge Reservation.

Thelma Rios was arraigned Oct. 6 on one count of felony murder in relation to kidnapping and one count of premeditated murder in the death of Annie Mae Aquash.

The 64-year-old Rios and John Graham are accused in state court of taking part in the kidnapping and killing of Aquash. Prosecutors say Aquash was killed because she was a suspected government informant against the American Indian Movement.

A federal criminal case against the 54-year-old Graham is on hold pending a request for an appeals court rehearing.
