These additional letters, according to the CT Insider report, corroborate aspects of the original account and suggest that multiple Skull and Bones members in the 1918 period believed their fellow members had stolen Geronimo’s skull and brought it to the Tomb.

The CT Insider report also included interviews with two descendants of Geronimo who stated that any skulls and other human remains that Skull and Bones took from Fort Sill should be subjected to DNA testing — a process they said they would be willing to participate in.

This was a significant development in the public discussion of the case.

The descendants were not just asserting that the remains should be returned; they were proposing a specific scientific mechanism for resolving the factual question of identification.

Their willingness to provide DNA for comparative testing changes the nature of the mystery.
