FMLN guerrillas led by Joaquín Villalobos, who had previously denounced Monterrosa and his command authority over the Atlacatl Battalion for carrying out the December 1981 civilian massacre in El Mozote, claimed responsibility for the helicopter crash. Monterrosa trained at the notorious School of the Americas and was hailed by American advisors as the army’s best field officer.
