The second of two men charged with killing a woman on Pine Ridge Indian Reservation in 1975 has asked to see the pre-sentence report of a third man already convicted of the crime.

John Graham and Richard Marshall are scheduled to stand trial in February on charges they committed or aided and abetted the first-degree murder of Annie Mae Aquash.

Arlo Looking Cloud was convicted in 2004 for his role.

Marshall's lawyer earlier filed a motion asking to view Looking Cloud's pre-sentence investigation report to determine if any information in it challenges his credibility should he testify against Marshall.

Marshall cited Looking Cloud's history of and treatment for mental disorders and alcohol and drug abuse.

Graham's lawyer has now filed a similar request.
