Cuernavaca became the host of the CIDOC ( Centro Intercultural de Documentación ) in 1961 , a Catholic institution that indoctrinated priests from developed countries before they were deployed elsewhere in Latin America . CIDOC 's lasting reputation was assured by its founding director Ivan Illich , though it closed , " a victim of its own success " , ten years later under right-wing political pressure . In the 1960s , the city became one of the centers of the psychedelic movement , attracting many artists , composers , and hippies . Another infamous resident was Sam " Momo " Giancana , a mafia boss associated with the Saint Valentine 's Day Massacre in Chicago , made Cuernavaca his home from 1967 until his arrest and deportation in 1974
