Overview

Anna Mae Pictou Aquash, a 30-year-old Mi'kmaq woman from Nova Scotia and a prominent member of the American Indian Movement, was taken from a house in Denver in late 1975 by three AIM associates, her hands bound, and driven to Rapid City, then across the Rosebud and Pine Ridge reservations, because AIM figures believed she was a government informant. On a bluff beside Highway 73 between Kadoka and Wanblee she was shot in the back of the head with a .32-caliber pistol. A rancher found her body on February 24, 1976. A first autopsy listed exposure; she was buried unidentified, and only after fingerprints identified her and she was exhumed did a second autopsy, on March 10, 1976, find the bullet. For 26 years the case went nowhere. Investigators made headway only after agents began talking to Arlo Looking Cloud in the mid-1990s and former AIM members, including an AIM leader's former wife who recorded conversations, broke their silence. Looking Cloud and John Graham were indicted in 2003. Looking Cloud was convicted of first-degree murder in federal court in February 2004 and sentenced to life. Graham, extradited from Canada in 2007, saw the federal case dismissed because he is not an American Indian under U.S. law; the State of South Dakota tried him instead, and on December 10, 2010 a Rapid City jury convicted him of felony murder in the kidnapping. He was sentenced to life without parole.

How it was solved

No physical evidence ever identified Aquash's killers; the second autopsy in March 1976 recovered a .32-caliber bullet too damaged to be matched to a gun, and the gun itself, by Looking Cloud's account, was buried under a bridge. The case was solved by witnesses who stopped being silent. The Eighth Circuit, affirming Looking Cloud's conviction in 2005, said the investigation made little headway until agents began talking to him in the mid-1990s. Around 2000 the former wife of an AIM leader began her own inquiry, interviewing Theda Clarke and Looking Cloud, who became emotional; at trial the defense said she was paid by the government and had recorded conversations. A Denver woman at whose house Aquash had been staying, a former girlfriend of Graham's who was in the house that night, and a woman whose home at Allen the group visited all eventually testified, with inconsistencies the defense exploited, about Aquash being led out with her hands tied, the phone call from Rapid City naming her as an informant, and the stop at Allen where, prosecutors said, the gun was obtained. In a videotaped interview Looking Cloud described the drive from Denver and said Graham fired the shot. A federal grand jury indicted both men in early 2003; Denver police arrested Looking Cloud in March 2003 and Graham was arrested in Vancouver that December. At Looking Cloud's trial in Rapid City in February 2004, before Chief Judge Lawrence Piersol, prosecutors argued that AIM members killed Aquash because they believed she was an informant; the jury took seven hours to convict. Graham's federal case collapsed on jurisdiction, because the Major Crimes Act reaches only Indians as defined by U.S. law, so Attorney General Marty Jackley obtained a state indictment in September 2009 and Canada consented to the state prosecution. Looking Cloud, by then serving life, testified in December 2010 that he stood nearby as Graham shot her; the jury convicted Graham of felony murder and acquitted him of premeditated murder. Jackley said afterwards that the investigation remained open.
