Circumstances of Disappearance Ray Robinson, who disappeared at the 1973 American Indian Movement takeover of the Pine Ridge reservation village of Wounded Knee, S.D., had deep ties to the civil rights movement. Robinson traveled to South Dakota in April 1973 and never returned. That was during a 71-day occupation of Wounded Knee by AIM members and supporters that included the exchange of gunfire with federal agents who surrounded the village. His body never was found and little is known about what happened. Reliable sources let it be known that Ray had been shot and killed at Wounded Knee and buried there. His wife, Cheryl Robinson said she filed a missing person's report with the FBI and in October 1974 traveled to Rapid City and then AIM headquarters in St. Paul, Minn., but learned nothing about what happened to her husband. Two Indians were confirmed to have died during the 1973 siege, and rumors of other deaths persist. FBI documents that now are public suggest the possibility of people buried at Wounded Knee during the occupation. It is unknown in which state his wife filed her missing persons report with the FBI. According to her they have not responded to any of her inquiries about her husband or his case.
