Upon arresting Guevara, Prado had planned to send him to be court martialed.[3] However, Bolivian President René Barrientos ordered his execution the next day.[4] At 11:30 that day, Terán walked into the schoolhouse room where Guevara was held prisoner and shot him dead with several shots of his M2 Carbine.[4] Sources conflict on the precise details of the events of the executions, including how Teran was selected to perform the execution. Some sources state that Terán volunteered for the job.[3] Other sources, including Guevara's brother, state that Terán had instead been chosen by his superiors and that he was reluctant to shoot Guevara.[5] Sources also disagree on the number of shots fired, with some saying that Guevara was killed in two shots[4] while others say that Terán fired at him nine times.[4]
