Alleged theft of Geronimo's skull Six members of the Yale secret society Skull and Bones, including Prescott Bush, served as Army volunteers at Fort Sill during World War I.[78] In 1986, former San Carlos Apache chairman Ned Anderson received an anonymous letter with a photograph and a copy of a log book claiming that Skull and Bones held the skull of Geronimo. He met with Skull and Bones representatives about the rumor. The group's attorney, Endicott P. Davidson, denied that the group held the skull and said that the 1918 ledger saying otherwise was a hoax.[79] The group offered Anderson a glass case like the one in the photograph containing what appeared to be the skull of a child, but Anderson refused it.[80] Geronimo's grave at Fort Sill, Oklahoma, in 2005 In 2006, Marc Wortman discovered a 1918 letter from Skull and Bones member Winter Mead to F. Trubee Davison that claimed the theft:[81] The skull of the worthy Geronimo the Terrible, exhumed from its tomb at Fort Sill by your club ... is now safe inside the [Tomb], and bone together with his well worn femurs, bit and saddle horn. — [81] The second "Tomb" refers to the building of Yale University's Skull and Bones society. The revelation led Harlyn Geronimo to write to President George W. Bush (the grandson of Prescott Bush) requesting his help in returning the remains: According to our traditions the remains of this sort, especially in this state when the grave was desecrated ... need to be reburied with the proper rituals ... to return the dignity and let his spirits rest in peace. — [82] However, the implications of the letter are debatable. Mead was not at Fort Sill, so he could not have personally witnessed the robbery, and Cameron University history professor David H. Miller notes that Geronimo's grave was unmarked at the time.[81] In 2009, Ramsey Clark filed a lawsuit on behalf of people claiming descent from Geronimo, against several parties including Robert Gates and Skull and Bones, asking for the return of Geronimo's bones.[79] An article in The New York Times states that Clark "acknowledged he had no hard proof that the story was true."[83] Investigators, including Bush family biographer Kitty Kelley and the pseudonymous Cecil Adams, say the story is untrue.[84][85] A military spokesman from Fort Sill told Adams, "There is no evidence to indicate the bones are anywhere but in the grave site."[84] Jeff Houser, chairman of the Fort Sill Apache tribe of Oklahoma, calls the story a hoax.[80] In 1928, the Army covered Geronimo's grave with concrete and provided a stone monument, making any possible examination of remains difficult.[83] In 2010, the court dismissed the case, deciding that Native American Graves Protection and Repatriation Act (NAGPRA) only applies to events that occurred after 1990. The court did not rule about the claim concerning Skull and Bones perhaps because NAGPRA does not apply to private organizations.[86][87][88]
