Throughout the 1970s, South Los Angeles was a place for families – blue-collar, hardworking moms and dads, streets filled with kids at play. These neighborhoods kept big city LA problems at bay. But the influx of gangs and crack cocaine of the early '80s changed everything. In addition to the drug-related problems, beginning in 1984, police noticed a rise in a specific type of crime: the bodies of young women started to show up one after another – in alleys, on playgrounds, and sometimes in plain view, as if on display. Authorities began referring to the serial killer responsible as the Southside Slayer. Families were devastated – and frustrated – as the body count rose and the bloodshed wreaked havoc on their community. But the truly terrifying details of this story came to light when investigators discovered a horrifying truth: the Southside Slayer wasn't one man, but four separate serial killers operating at the same time in the same place.
