The Black Hole of Guyana:
The Untold Story of the Jonestown Massacre
by John Judge, 1985
"The direct orders to cover up the cause of death came from the top levels of the American government. Zbigniew Brzezinski delegated to Robert Pastor, and he in turn ordered Lt. Col. Gordon Sumner to strip the bodies of identity.Pastor is now Deputy Director of the CIA. One can only wonder how many others tied to the Jonestown operation were similarly promoted."
