The tape is roughly seventeen minutes long. It was recorded inside a windowless cargo van parked in the San Gabriel Mountains north of Los Angeles on the night of October 31, 1979. It captures the murder of a sixteen-year-old girl named Shirley Lynette Ledford. The two men in the van had picked her up that evening as she walked home from a Halloween party in Sunland, California.

The cassette was found in their van four weeks later, packaged in a small plastic bag along with several Polaroid photographs and a fresh roll of duct tape, when the Hermosa Beach Police arrested the two men on an unrelated rape charge. It became, almost immediately, the central piece of physical evidence in the trial of California v. Bittaker and Norris. It has, since then, been used by the FBI Academy at Quantico as a training tool in interrogation and behavioral analysis. Specific FBI agents have, in the years since, given media interviews in which they describe being unable to finish a listen. One former Behavioral Science Unit profiler, Roy Hazelwood, told an Atlantic interviewer in 2003 that he played a section of the tape exactly twice in his career and was certain he would never play it a third time.

Forty-seven years later, the tape remains under court seal in the Los Angeles County District Attorney’s office. Excerpts have been played at exactly one public proceeding: the 1981 sentencing trial of Lawrence Sigmund Bittaker. The two killers — Bittaker and his accomplice Roy Lewis Norris — are both dead. Of the five teenage girls they murdered in the summer and fall of 1979, the youngest was thirteen and the oldest was eighteen. None of them has ever entered the cultural memory of true crime the way their killers’ tape has. It was, in every direction the case touched, a story that was difficult to keep at the center of the lives that mattered.

Two men who should not have been free

Lawrence Bittaker and Roy Norris met in May 1978 at the California Men’s Colony, a medium-security state prison in San Luis Obispo. Bittaker, thirty-eight, was serving a sentence for assault with a deadly weapon — the latest in a long string of violent convictions stretching back to his teens. Norris, twenty-nine, was serving a sentence for forcible rape after a series of escalating attacks on women in southern California in the early 1970s.

They became cellmates and, within months, friends. According to prison counselors who interviewed them after their later arrests, the two men began openly discussing during 1978 a fantasy of finding, kidnapping, and killing teenage girls together once they were released. The fantasy was specific: a girl of each age from thirteen through nineteen. They wanted, Norris would later testify, to “catch a teenager of every age.”

Norris was paroled in June 1979. Bittaker was paroled five months earlier, in early February 1979. By the standards of the California parole system as it functioned at the time — a system that was running well above its rated capacity and that had only minimal psychiatric review for parolees with violent histories — both men had served the sentences the courts had given them. There were no remaining grounds to hold them. Bittaker had assured the parole board that he intended to live with his elderly mother and look for stable work as a mechanic. He had instead moved to a small apartment in southern Los Angeles County, bought a 1977 GMC cargo van with the words Murder Mac spray-painted on the dashboard (out of view of anyone who did not climb inside), and waited for Norris to be released.

By the second week of June 1979, less than two weeks after Norris was paroled, the two men were driving through the foothills and beach communities of Los Angeles County in the Murder Mac, looking for what they had described to each other in their cell as their first “project.”

Five names, in four months

The first was Lucinda Lynn Schaefer, sixteen. On the evening of June 24, 1979, Cindy — as her family called her — was walking home from a youth group meeting at the Lutheran Church of the Master in Redondo Beach. The two men offered her a ride. She refused. They forced her into the van. She was driven to the San Gabriel Mountains and killed there several hours later.

The second was Andrea Joy Hall, eighteen, an aspiring nurse working a summer job. She was hitchhiking on the Pacific Coast Highway in Manhattan Beach on July 8, 1979. They picked her up. She, too, was driven into the mountains.

The third and fourth were Jackie Doris Gilliam, fifteen, and Jacqueline Leah Lamp, thirteen. They were close friends, headed to the beach together at Hermosa Beach on the afternoon of September 3, 1979. The two men offered them what they later told other potential victims was “a free ride and some music.” Both girls were killed in the mountains within the next twenty-four hours.

The fifth was Shirley Lynette Ledford, sixteen, walking home from a Halloween party in Sunland on the night of October 31, 1979. Unlike the previous four victims, Ledford was killed inside the van that same night and her body left in a residential yard in Tujunga, where it was discovered by a passing motorist at dawn. She was the only one of the five whose body was recovered before the men were caught. The audio cassette that would become the case’s central piece of evidence was recorded during her abduction.

A survivor, and a tip from a prison friend

There was a sixth, intended victim who survived. In mid-September 1979, the two men picked up a young woman at a Hermosa Beach bus stop, drove her partway up into the foothills, and were preparing to assault her when she successfully fought her way out of the van and escaped on foot. She made it to a residential street and flagged down a passing driver, who took her to the Hermosa Beach Police. She gave a detailed statement, including a description of the van and a partial license plate. The Hermosa Beach Police, after some delay, filed the report and circulated the description.

The break in the case came not from the survivor’s report — although it would later be matched up — but from inside Roy Norris’s social circle. In November 1979, Norris bragged about the killings to a former prison acquaintance named Joe Jackson. Jackson, who had himself only recently been paroled and was not interested in being implicated in a chain of murders, walked into the West Los Angeles Police Station and told a detective everything Norris had told him.

The Los Angeles Police, cross-referencing Jackson’s tip against the Hermosa Beach kidnapping report, surveilled Norris for several days. On November 20, 1979, both men were arrested. Initially the arrests were on the unrelated rape and kidnapping charge from the Hermosa Beach case. The audio tape, the Polaroids, and the names of the other four missing girls were found during the subsequent search of the van and of Bittaker’s apartment over the next forty-eight hours.

The deal, and the trial

Faced with the audio tape, the Polaroids, and the matched physical evidence from the four prior killings, Norris’s defense attorney moved quickly to negotiate. In a plea agreement reached in early 1980 with Deputy District Attorney Stephen Kay of the Los Angeles County District Attorney’s office, Norris agreed to plead guilty to five counts of first-degree murder and to testify against Bittaker in exchange for the prosecution not seeking the death penalty against him. He was sentenced to forty-five years to life, with parole eligibility beginning in 2010.

Bittaker refused to plead. His trial, held in early 1981 in Los Angeles County Superior Court before Judge Edward Hinz Jr., lasted seven weeks. Norris was the prosecution’s principal witness. The audio tape was played in the courtroom on a single afternoon, with the jury present, the gallery cleared, and the families of the victims given the option of remaining in the room or leaving. Most of them left. The jury returned a verdict of guilty on all five counts of first-degree murder and recommended the death penalty for each. Judge Hinz formally sentenced Bittaker to death on March 24, 1981, and remarked from the bench that the case was the worst he had presided over in twenty-six years.

Death row, and natural causes

California has not executed a prisoner since 2006. The state has a moratorium on executions imposed by Governor Gavin Newsom in March 2019, but the underlying death-penalty statute and the prisoners on California’s death row remain in place pending future political resolution. Lawrence Bittaker, sentenced to death in 1981, remained on death row at San Quentin State Prison for thirty-eight years. He gave occasional interviews to true-crime writers and corresponded with several pen pals from his cell. He never expressed remorse in any public forum.

He died of natural causes on December 13, 2019, at age seventy-nine. He had outlived all five of his victims by an average of forty years.

Roy Norris, serving his sentence at the California Health Care Facility in Stockton, became eligible for parole in 2010 and was denied at every hearing. He died of natural causes on February 24, 2020 — about ten weeks after Bittaker — at age seventy-one. He never apologized publicly to the families of the five girls he and Bittaker had killed.

The tape that does not go away

The Bittaker-Norris tape is, by any honest reckoning, the single most psychologically damaging piece of audio evidence in modern American criminal investigation. It is held in the Los Angeles County District Attorney’s evidence vault. Several copies exist in FBI evidence custody. The FBI Academy uses brief sections in interrogation training, in agent-resilience training, and in the agency’s preparation of new behavioral profilers — specifically to teach them what their actual job exposure may include, before they have to manage the exposure on a real case.

Several FBI veterans have given interviews over the years describing the long-tail psychological cost of having heard the tape. Roy Hazelwood, who profiled the Bittaker-Norris case and consulted on dozens of similar partnerships in his career, said in a 2003 Atlantic interview that the tape gave him nightmares for years afterward. Special Agent John Henry Hingson, who used the case in his FBI Academy lectures, has said publicly that he would not allow recordings of the tape to be made available outside the bureau and would oppose any future request to declassify it.

The tape’s existence has also been used by abolition advocates as one of the small handful of cases where even firm opponents of the death penalty have, in unguarded moments, struggled to make a principled defense of indefinite custody. It has been used by death-penalty supporters as the single case they will name when asked for an example. It has been used by victim’s-rights advocates to argue against the public release of any audio of the killings of the families’s children. The Schaefer, Hall, Gilliam, Lamp, and Ledford families have, for forty-five years, asked the same thing of every documentary maker, true-crime author, and podcaster who has approached them: do not play any part of the tape. Most have honored that request.

What this case was supposed to be about

The Toolbox Killers case is remembered, in the small subgenre of true crime that has chosen to remember it, almost entirely through the lens of its perpetrators — their partnership, their tape, their refusal to apologize. That is, on a strict accounting, the wrong shape. The case was always about five teenage girls in the summer and fall of 1979 in southern California who were attacked while doing nothing more dangerous than walking home from a youth group meeting, hitchhiking to the beach in an era when teenagers in southern California still hitchhiked to the beach, and walking back from a high school Halloween party. They lived in a region that, for a few months, was being trawled by two men who had been let out of state prison too soon by a parole system that did not have the will or the resources to keep them in.

Cindy Schaefer was sixteen and wanted to be a teacher. Andrea Hall was eighteen and had just been accepted into nursing school. Jackie Gilliam was fifteen and on her school’s swim team. Jacqueline Lamp was thirteen and a straight-A eighth-grader. Lynette Ledford was sixteen and the youngest of three sisters in a working-class Tujunga family. They were each, at the moment they died, ordinary southern California teenagers whose families were planning the rest of the school year.

Their killers are dead. The tape is sealed. The men who heard the tape, and who could not unhear it, mostly retired. The five families, in the four and a half decades since, have done their best to keep the names of their children — not their killers’ names — as the thing that is remembered. It is harder than it should be.
