Overview: Five bodies, riddled with bullets, found in a small apartment on the East Side of Los Angeles. Among the dead are a five-year-old boy and an infant girl, each shot in the head and chest. The mother and father of the children lay beside them on the floor, also soaked in blood. The target of the hit was the family's patriarch, Anthony "Dido" Moreno. He had dropped out of one of California's most notorious prison gangs and this was his payback. No witnesses, was the order. The gang he deserted was the Mexican Mafia. Since it's inception in the 1950's the "Black Hand" has been the prison system's most active shot-callers, controlling thousands of "foot soldiers" on the streets of Southern California. Most laws enforcement officials estimate that 300 homicides per year in LA County have some connection to the Mexican Mafia.
