The Monster of the Mangones is the name given to an unidentified Colombian serial killer who,[1] between the 1960s and 1970s, murdered between 30 and 38 preadolescent and teenage boys in Cali.
[2] During the 1960s, citizens of Cali lived in fear and uncertainty, as children and adolescents began disappearing from the area.
After that, more cases of murdered young boys began cropping up, the bodies discarded in a type of urban alley known as mangones.
In January 1964, Cali police found the mummified body of another boy; two days after, the remains of 12-year-old Alberto Garzón were discovered.
Faced with this wave of murders, the authorities sent a series of notices to the public, claiming that these bodies were likely taken from cemeteries and later scattered around Cali, mostly in solitary areas.
