FILE - This undated file photo provided by the Robinson family shows civil rights activist Ray Robinson. Documents recently released by the FBI to a Buffalo, N.Y., lawyer shed new light on the 40-year-old case of Robinson, an activist and follower of Martin Luther King Jr. The FBI says Robinson was killed during the 1973 occupation of Wounded Knee, and it suspects militant members of the American Indian Movement are responsible. His body was never found. (AP Photo/Courtesy of the Robinson Famiily, File) less
