Lonnie David Franklin Jr. terrorized South Los Angeles for over two decades, using a .25 caliber handgun to murder young women in the city's poorest neighborhoods. The man who would become known as the Grim Sleeper claimed at least 10 victims, though investigators suspected the true number could be higher.

Franklin's first confirmed murder occurred in August 1985 when 29-year-old Debra Jackson was shot and left in an alley. What followed was a pattern of violence targeting vulnerable women—many of them sex workers or drug users aged 15 to 35—whose bodies were dumped outdoors in alleys, dumpsters, and bushes across South Los Angeles.

The killer operated in two distinct periods. The first wave of murders stretched from 1985 to 1988, claiming multiple victims before the murders stopped. Then, more than a decade later, the killings resumed in 2002 and continued until 2007. The sudden gaps in activity—the longest spanning 14 years—left investigators puzzled and made the case increasingly difficult to solve.

By January 1986, just months after the first murder, the LAPD had assembled a 49-member task force to hunt the killer. Investigators called him the "Southside Slayer," but the nickname never stuck in public consciousness. Franklin's violent campaign would remain largely unsolved for nearly 25 years.

The breakthrough came not from traditional detective work, but from advances in forensic science. In 2008, familial DNA analysis—a technique that searches for genetic matches to relatives in criminal databases—linked Franklin to a conviction on his son Christopher Franklin's record. This crucial lead finally gave investigators what they needed: a name.

Franklin was arrested on July 7, 2010, at age 57. When authorities searched his garage, they discovered a chilling archive: photographs of hundreds of women, weapons, and numerous identification cards. The evidence painted a picture of obsession and predatory behavior spanning decades.

The case against Franklin was methodical and thorough. On May 5, 2016—more than six years after his arrest—he was convicted of 10 counts of first-degree murder with the special circumstance of multiple murders. He was also convicted of the attempted murder of Enietra Washington, who survived an attack on November 19, 1988. The conviction carried an automatic sentence: death.

Franklin remained on death row until his death on March 28, 2020, never facing execution. By that time, he was 67 years old.

The Grim Sleeper case highlighted a grim reality that persists in American policing: the disproportionate vulnerability of Black women, sex workers, and those struggling with addiction. For years, these murders received minimal media attention and limited investigative resources. Many of Franklin's victims were discovered weeks or months after their deaths, with little urgency surrounding their cases.

The case also underscored the power of familial DNA technology, which has since become a controversial but effective investigative tool. What traditional police work could not accomplish over 25 years, genetic databases solved in a matter of years.

Today, the Grim Sleeper case remains a watershed moment in American true crime history—a reminder both of how long serial killers can evade justice and of how new forensic technologies can finally bring closure to decades-old mysteries.
