The U.S. Army announces that Colonel Robert B. Rheault, Commander of the Fifth Special Forces Group in Vietnam, and seven other Green Berets have been to commit murder in the summary execution of a Vietnamese national, Thai Khac Chuyen, who had served as an agent for Detachment B-57. Chuyen was reportedly summarily executed for being a double agent who had compromised a secret mission.
The case against the Green Berets was ultimately dismissed for reasons of national security when the Central Intelligence Agency refused to release highly classified information about the operations in which Detachment B-57 had been involved. Colonel Rheault subsequently retired from the Army.
