A man who was found guilty of murdering American Indian Movement activist Anna Mae Pictou Aquash contradicted prior testimony in the case and said he was wrongfully convicted for the crime.

Arlo Looking Cloud, a member of the Oglala Sioux Tribe, was convicted of Aquash's murder in 2004. He lost an appeal and decided to cooperate with federal prosecutors as they went after Richard Marshall, also Oglala.

But when called to the stand in Marshall's trial, Looking Cloud appeared to change his story about the December 1975 incident. On Thursday, he testified that he saw Marshall take a gun that was used to murder Aquash -- a key element of the charges against Marshall.

That's contrary to testimony presented at Looking Cloud's trial in 2004, when a witness said Looking Cloud admitted he supplied the gun. Looking Cloud never challenged that testimony at trial or on appeal.

Looking Cloud also denied telling former AIM leader John Trudell about Aquash's murder but Trudell testified to the contrary in 2004. Again, it appears Looking Cloud never challenged the testimony.

Marshall has denied supplying the gun that was used to kill Aquash. Prosecutors allege a third man, John Graham, was the one who actually pulled the trigger.

Graham, who is Native from Canada, will go to trial in state court in connection with Aquash's murder. He was initially indicted in federal court but the charges were dismissed because he isn't a member of a federally recognized tribe.
