Brothers, you came from our own people. You are killing your own brothers. Any human order to kill must be subordinate to the law of God, which says, 'Thou shalt not kill'. No soldier is obliged to obey an order contrary to the law of God. No one has to obey an immoral law. It is high time you obeyed your consciences rather than sinful orders. The church cannot remain silent before such an abomination. ... In the name of God, in the name of this suffering people whose cry rises to heaven more loudly each day, I implore you, I beg you, I order you: stop the repression.

After his death the UN Truth Commission reported:
In November 1987, Amado Antonio Garay ...revealed that on 24 March 1980, Saravia had ordered him to drive a red Volkswagen to the Hospital . He had parked opposite the Chapel. His passenger, a bearded stranger, had ordered him to crouch down and pretend to be repairing something. He had heard a shot, turned around and seen the individual holding a gun with both hands pointing towards the right side of the rear right window of the vehicle. He had immediately smelt gunpowder and at that moment the bearded man had calmly told him: drive slowly, take it easy' and they [drove] off. Garay alleged that he had driven the individual to former Captain Saravia, to whom the stranger had said 'mission accomplished'. Three days later, Garay had driven Saravia to a house where former Major D'Aubuisson was and Saravia had said in front of D'Aubuisson: 'We've already done what we planned about killing Monsignor Arnulfo Romero'.
Findings: The Commission Finds the Following: 1. There is full evidence that [F]ormer Major Roberto D'Aubuisson gave the order to assassinate the Archbishop and gave precise instructions to members of his security service, acting as a 'death squad', to organize and supervise the assassination.
No-one was ever charged with the murder. The investigating magistrate fled the cuntry after death threats. d'Aubuisson's party, ARENA went on to dominate Salvadoran politics from 1989 to the present. El Salvador is a member of the coalition of the willing.
