The first body was found beneath a discarded carpet in an alley near West Gage Avenue in the Vermont-Slauson area of South Los Angeles. She was Debra Jackson, 29, a cocktail waitress who had left a friend’s house in Lynwood on the evening of August 10, 1985, and walked toward the bus stop that would take her back to her apartment. She had been shot three times in the chest with a . 25 caliber pistol.

Three days passed before anyone noticed her. That crime scene contained a biological signature that would surface again and again over the next 23 years. The same DNA profile turned up at ten separate crime scenes across South Los Angeles. The victims were Henrietta Wright, 35; Barbara Ware, 23; Bernita Sparks, 26; Mary Lowe, 26; Laquanda Jefferson, 22; Alicia Alexander, 18; Princess Bertemu, 15; Valerie McCorvey, 35; and Janecia Peters, 25.

They had been shot, strangled, beaten, or some combination of all three. Their bodies were left in alleys, in trash bags, and in vacant lots, disposed of with a familiarity that suggested someone who knew exactly which streets stayed dark and which alleys stayed empty. A neighbor told detectives she had seen Mary Lowe climb into a reddish-orange Pinto on the night she disappeared. The car pulled away and vanished, and Mary Lowe was never seen alive again.

The detail led nowhere at the time. The victims were not strangers to one another’s streets. They were daughters, sisters, and mothers who lived within a few square miles of each other in a community of working people, sanitation workers, mechanics, nurses, and teachers. South Los Angeles in the mid-1980s was a neighborhood shaped by deliberate disinvestment, and the women who disappeared from it did not receive the kind of institutional response that might have found their killer sooner.

Within the LAPD, some officers used the acronym NHI, no humans involved, to describe cases involving Black women who were sex workers, drug users, or simply poor. It was never written into policy, but its effect was a hierarchy of urgency that placed these deaths at the bottom. Margaret Prescott founded the Black Coalition Fighting Back Serial Murders in 1985, within months of the first confirmed killings, because the response she was observing did not reflect the urgency that the deaths of multiple women in a single neighborhood should have produced. She brought the victims’ names to press conferences.

She argued on the record that these women were receiving less attention because of who they were and where they lived. The investigation continued for years. More than 100 persons of interest were formally interviewed. A $500,000 reward was offered.

Task forces were assembled, deactivated, and reassembled. Biological evidence recovered from the crime scenes was submitted to CODIS, the Combined DNA Index System, and the profile remained accurate and intact across two decades of storage. Repeated searches returned no match. There was one survivor.

In November 1988, Enietra Washington accepted a ride from a man in an orange Ford Pinto. He shot her in the chest, sexually assaulted her, took a Polaroid photograph of her as she bled, and pushed her from the moving vehicle. She survived. From her hospital bed, she described the house where he had taken her.

A month later, a detective drove her through the streets, and she spotted a small Spanish bungalow on West 81st Street and cried out, “This is the house. ”

The LAPD set up surveillance in an abandoned storefront across the street. For one month, teams of officers watched and waited. But the house they were watching was number 1742.

The house they should have been watching was number 1728, three doors away. They had the right street, the right survivor, and the right description. They just had the wrong door. The man they were hunting was close enough to wave to, and they never knew it.

The case grew cold. But the evidence did not degrade. DNA, unlike witness memory and unlike institutional momentum, does not require ongoing maintenance to remain accurate. In 2008, journalist Christine Pelisek of the LA Weekly published an investigation that gave the killer the name by which he became publicly known: the Grim Sleeper.

She identified a 14-year gap in the confirmed killings and documented the pattern when placed in sequence. The coverage reignited public attention and prompted the LAPD to reactivate the task force. But the investigation still had no suspect and no mechanism for producing one. The man it was looking for lived a few blocks from where some of his victims had been found.

He was a city employee who had worked as an auto mechanic in the LAPD’s vehicle maintenance division, servicing the fleet operated by the department whose task force could not locate him. He attended community meetings about the Grim Sleeper killings. He was the kind of neighbor who was recognized by name, who fit the texture of the block well enough to be unremarkable. In 2003, he was convicted of a felony and served time, but his DNA was not collected because of an administrative gap, and he was released early due to overcrowding.

The system had him in its hands and let him go. In 2008, California became the first jurisdiction in the United States to formally authorize familial DNA searching at the prosecutorial level. A standard CODIS search looks for an exact match. A familial search looks for a near match, a profile similar enough to indicate that a close biological relative is already in the database.

If a man’s son has been convicted of a felony and his DNA is on file, that son’s profile carries a familial echo of his father’s across enough shared markers for an algorithm to flag the proximity. In November 2008, the California Department of Justice Forensic Laboratory in Richmond, under Attorney General Jerry Brown, initiated the first familial search for the Grim Sleeper suspect. It failed. No relative was yet in the database.

On April 28, 2010, a second search was initiated. This time it returned something. A young man convicted on a felony weapons charge had submitted a DNA sample. His Y chromosome markers aligned with the Grim Sleeper profile so closely that forensic scientists determined he must be a first-degree paternal relative: a son, a brother, or a father.

The age of the contributor eliminated the young man himself. But his father was still alive, and he lived in South Los Angeles. The father’s name was Lonnie David Franklin Jr. , 57, and the address on his record was 1728 West 81st Street, the house three doors down from the one police had watched in 1988.

He was a retired city employee who had worked for years in the LAPD’s vehicle maintenance division. He had been married for more than 30 years. He returned each evening to a neighborhood where his face was known and his presence carried no particular significance. In early June 2010, LAPD placed Franklin under round-the-clock surveillance with 14-to-16-member teams from the Special Investigation Section and Narcotic Surveillance.

He spent his days inside, venturing out only for mundane errands. At night, he took long, seemingly pointless drives. On occasion, he drove along Western Avenue, an area known for prostitution. Detectives feared he might strike again.

Their break came when Franklin stopped at a pizzeria near Buena Park. He ate a slice and left the crust, a fork, napkins, and a drinking glass on the table. An undercover detective posing as a waiter collected eight items and delivered them to the LAPD’s DNA lab. The analysts were not told what case they were working on, but they were instructed to rush the job without cutting corners.

The genetic profile recovered from that crust was a statement of identity, not a probability. The chance of coincidental occurrence was documented as less than one in one quadrillion. On July 7, 2010, LAPD officers arrested Lonnie Franklin Jr. at his home without incident.

Police Chief Charlie Beck stated, “We have arrested the Grim Sleeper serial killer. ” Attorney General Jerry Brown added, “In the face of a multitude of objections, we’ve crafted a balanced policy to respect the rights of citizens and at the same time deploy the most powerful DNA search technology available. ”

Franklin was charged with 10 counts of first-degree murder and one count of attempted murder. His defense team moved to suppress the DNA evidence obtained from the pizza crust, arguing that it had been collected without a warrant.

Superior Court Judge Kathleen Kennedy denied the motion in a single sentence, calling the argument “specious and ridiculous. ” The pizza crust stayed in the record. Enietra Washington, the sole surviving victim, took the stand. She pointed at Franklin and said she was 100 percent certain.

She described the orange Pinto, the Polaroid camera, the sound of gunfire. On May 5, 2016, the jury returned guilty verdicts on all 10 counts of murder and on the attempted murder charge. On June 6, 2016, the jury recommended the death penalty. On August 10, 2016, Judge Kennedy sentenced Lonnie Franklin Jr.

to death for each of the 10 victims. As she read each name, she repeated, “You shall suffer the death penalty. ”

When investigators searched Franklin’s home following his arrest, they found more than 180 photographs of women, many of them unidentified, suggesting that the confirmed victim count may not represent the full scope of what had been done across those 26 years. Franklin did not live to face execution.

On March 28, 2020, he died at San Quentin State Prison from natural causes at the age of 67, having never publicly acknowledged what he had done and having left no statement of record that established his motive across any of the 10 confirmed killings. The photographs found in his home remained an open question, a standing archive of faces that the investigation had not yet been able to match to names, to cases, and to families who were still waiting. The families who lost someone to this man were not failed by the science of their era. The science that eventually identified him was genuinely new.

They were failed by the institutional judgment of people who had the authority to direct greater resources toward the investigation and made a different choice across years and then decades. What the killer relied on, what allowed him to sit in the community meetings organized to find him, to be employed by the institution searching for him, and to go home each evening to the same block where some of his victims had lived, was not a technical limitation. It was the presence of a hierarchy that had already determined, in practice if not in policy, whose disappearance would produce urgency and whose would produce a file.
