Moren Brito was accused of the widespread abductions, disappearances, murder and the torture of political opponents of the Pinochet regime.^[1] La Tercera, the daily Chilean newspaper, wrote that Moren Briten was "associated with some of the cruelest actions of repression against dissidents of the military government of Augusto Pinochet."^[1][2]

Moren Brito was convicted of crimes against humanity and sentenced to more than 300 years in prison.^[1][2] He was incarcerated for life at Punta Peuco Prison, which was constructed in 1995 specifically for individuals convicted of human rights abuses.^[1]
