Theda Clarke, Oglala Sioux Tribe member and activist with the American Indian Movement most known for her connections in the 1975 killing of fellow AIM activist Annie Mae Pictou Aquash, died Tuesday.
Clarke, 87, who was suspected of being involved in the murder that took place on the Pine Ridge Indian Reservation in South Dakota had been suffering from the effects of a stroke, dementia, diabetes and other ailments according to court records the Associated Press reports.
Clarke who constantly refused to cooperate in the investigation that has been linked to tainting the legacy of the AIM was ruled competent to testify in December during the murder trial of John Graham.
Clarke, Graham and Arlo Looking Cloud allegedly drove Aquash in Clarke’s Ford Pinto from Denver to Rapid City, where they held her against her will for questioning as to whether she was a federal informant, before killing her.
Graham and Looking Cloud were both convicted and are serving prison sentences. Clarke was never charged.
