In August 1989, Marcelo Barrios Andres, a 21-year-old member of the Manuel Rodríguez Patriotic Front (FPMR, the armed wing of the PCC, created in 1983, which had attempted to assassinate Pinochet on 7 September 1986), was assassinated by a group of military personnel who were supposed to arrest him on orders of Valparaíso's public prosecutor. However, they simply summarily executed him; this case was included in the Rettig Report. Among the killed and disappeared during the military dictatorship were 440 MIR guerrillas.
