Francisco Rolando Aguayo Cabañas, while a member of the Yungay Regiment of San Felipe, was part of the squads that murdered leaders of the Unidad Popular in that area and in the northwest of Santiago. He continued in the CNI and retired in the 1980s as a sergeant major.

Retired Colonel Fernando Reveco Valenzuela, who testified before Judge Juan Guzmán Tapia in the proceedings against Pinochet in May 1999, stated: "Major Cruz informed me that at some point he saw Pinochet witness the torture of members of the GAP. From the place where he was positioned, due to the lighting, he could not be seen by those being tortured, nor by the torturers."

Major Cruz has also been cited in the book "Chile: La memoria Prohibida" as follows: "The authors had access to a testimony whose source they reserve, where the names of seven officers and non-commissioned officers are provided who allegedly formed the custody group responsible for the execution by firing squad of Eduardo Paredes and twenty-six members of the GAP.

Those names are: a certain Major Cruz, Lieutenant Herrera, a non-commissioned officer with the surname Aguayo, two sergeants—one with the surname Mendoza (who ended up with a broken arm in the struggle with the prisoners) and another named Francisco Aguayo Cabañas—and two corporals, Gamboa and Martínez."
