The Golden State Killer

Visalia, California, United StatesJune 18, 1975

Beginning in the mid-1970s and continuing through the 1980s, a predator operating across California committed an extraordinary series of crimes that would remain unsolved for over four decades. He was known by multiple names as his crimes evolved — the Visalia Ransacker, the East Area Rapist, the Original Night Stalker — before the cases were linked and he was collectively dubbed the Golden State Killer. He committed at least 13 murders, more than 50 sexual assaults, and over 100 residential burglaries across dozens of California communities.

Investigators were long baffled by the perpetrator's intelligence and discipline. He would surveil neighborhoods for weeks before striking, disabling porch lights, unlocking windows, and memorizing the layouts of homes. During assaults, he often called victims on the phone before or after attacks, taunting them. He left minimal physical evidence, and although a DNA profile was developed from crime scenes, it matched no one in existing databases for decades. Victims, investigators, and true crime researchers spent years piecing together the case with little progress.

The breakthrough came in 2018 through genetic genealogy — investigators uploaded the killer's DNA to the public ancestry website GEDmatch and traced distant relatives, eventually narrowing to Joseph James DeAngelo, a 72-year-old former police officer living in suburban Sacramento. DNA recovered from a discarded item confirmed the match. DeAngelo was arrested in April 2018. In 2020, he pleaded guilty to 13 counts of first-degree murder and admitted to the other crimes in exchange for life in prison without the possibility of parole.

The Golden State Killer case transformed law enforcement's approach to cold cases, sparking widespread adoption of investigative genetic genealogy as a tool. It also sparked significant ethical and legal debates about privacy and the use of consumer DNA databases by law enforcement — debates that continue today. Author Michelle McNamara, who coined the name "Golden State Killer" and spent years investigating the case, died in 2016, two years before his capture; her posthumous book 'I'll Be Gone in the Dark' became a bestseller and critically acclaimed HBO documentary.

The Zodiac Killer

San Francisco, California

Between 1968 and 1969, a serial killer who called himself the Zodiac sent a series of taunting letters to San Francisco Bay Area newspapers, claiming responsibility for at least five confirmed murders in Vallejo, Napa, and San Francisco. The killer used a distinctive crosshair symbol as his signature, encrypted his communications in ciphers, and made specific threats that created widespread public terror throughout Northern California. He claimed in his letters to have killed as many as thirty-seven people, though investigators confirmed only five deaths with certainty. The Zodiac killed couples at lover's lane locations, a taxi driver, and attacked survivors who were able to provide witness descriptions. The investigation involved multiple law enforcement agencies across several counties and generated hundreds of thousands of tips over the following decades. A partial palm print was obtained; witness descriptions produced composite sketches; handwriting analysis was conducted. Despite the killer's unusual willingness to communicate — sending over thirty letters to police and newspapers — the Zodiac was never identified or arrested. A prime suspect named Arthur Leigh Allen, a convicted sex offender, was investigated extensively for decades but was never charged; DNA testing in 2002 did not match evidence from crime scenes, though investigators noted limitations in the samples available. Three of the Zodiac's four encrypted ciphers remained unsolved for decades. The first cipher was cracked by amateur code-breakers in 1969. The 340-character cipher — so named for its length — was solved in December 2020 by an international team of amateur cryptanalysts, yielding a taunting message that provided no identifying information. The 13-character cipher, sent with a letter claiming to contain the killer's name, has never been solved. The Zodiac Killer became one of the most culturally pervasive unsolved murder cases in American history, inspiring David Fincher's acclaimed 2007 film "Zodiac" based on Robert Graysmith's books, countless documentaries, and a permanent community of online investigators. As of 2025, the Zodiac's identity remains officially unknown, though the San Francisco Police Department officially lists the case as open. The case is the paradigmatic example of how a killer's deliberate cultivation of mystery can ensure lasting infamy.

The Manson Family Murders

Los Angeles, California

In the late 1960s, Charles Manson — a charismatic ex-convict with messianic delusions — assembled a commune of mostly young, vulnerable followers at Spahn Ranch near Los Angeles, California. Manson preached an apocalyptic ideology he called "Helter Skelter," named after a Beatles song, which predicted a coming race war he intended to trigger through acts of spectacular violence. On the night of August 8–9, 1969, Manson sent four followers — Tex Watson, Susan Atkins, Patricia Krenwinkel, and Linda Kasabian — to the home of film director Roman Polanski on Cielo Drive, where they murdered five people including pregnant actress Sharon Tate. The following night, a different group killed Leno and Rosemary LaBianca in their home nearby, leaving the word "HEALTER SKELTER" scrawled in blood on the refrigerator. Los Angeles police initially failed to connect the two crime scenes. The break came when Susan Atkins, jailed on an unrelated charge, boasted about the murders to a cellmate. Atkins and other Family members were arrested in late 1969; Manson was already in custody on an unrelated weapons charge. The subsequent investigation revealed the full scope of the Family's violence, which investigators came to believe included additional murders. Linda Kasabian agreed to testify for the prosecution in exchange for immunity. The Manson Family trial, beginning in June 1970, was among the most circus-like in American history: Manson carved an X into his forehead during proceedings, the female defendants shaved their heads and sang on the courthouse steps, and Manson threatened and intimidated witnesses. All four primary defendants — Manson, Atkins, Krenwinkel, and Watson — were convicted of first-degree murder and sentenced to death. Those sentences were automatically commuted to life imprisonment when California briefly abolished the death penalty in 1972. Charles Manson was denied parole twelve times before dying of cardiac arrest in November 2017 at age eighty-three. The case fundamentally changed American perceptions of cult danger, the vulnerability of young people to charismatic manipulation, and the fragility of the idealistic counterculture. Manson became a grotesque cultural icon — his face among the most recognized symbols of evil in American history — and the murders are still widely cited as the moment the innocent spirit of the 1960s definitively ended.

Ted Bundy

Seattle, Washington

Ted Bundy was one of the most notorious and charismatic serial killers in American history, using his intelligence, charm, and good looks to gain the trust of victims before attacking them. During the 1970s he kidnapped, raped, and murdered numerous young women across multiple states, confessing shortly before his execution to 30 homicides committed in seven states between 1974 and 1978. Investigators believe the true number may be considerably higher. Bundy's crimes spanned the country from the Pacific Northwest through Utah, Colorado, and Florida. He escaped from custody twice — once from a courthouse law library in Aspen and once from a county jail in Glenwood Springs — and was at large for a combined period that allowed him to commit additional murders. His second escape culminated in the January 1978 Chi Omega sorority house attack in Tallahassee, Florida, in which he bludgeoned four women and killed two, and the subsequent abduction and murder of twelve-year-old Kimberly Leach. Bundy was convicted in Florida of the sorority house murders and the Leach murder in two separate trials, both of which he attended as his own attorney — a decision widely seen as an exercise in narcissistic control. He was sentenced to death three times. On death row he gave extensive interviews to investigators and journalists, and began confessing to murders as his execution date approached — confessions many believe were deliberately incomplete to extend negotiations. He was executed in Florida's electric chair on January 24, 1989. His execution attracted a crowd of supporters and protesters outside the prison. Bundy's case had a lasting influence on American criminal justice, contributing directly to the development of the FBI's behavioral science unit and the concept of the organized serial killer. He remains a subject of intense cultural fascination, having inspired dozens of books, films, and documentaries.

The Night Stalker

Los Angeles, California

Richard Ramirez — a twenty-five-year-old drifter from El Paso, Texas — terrorized the greater Los Angeles area and the San Francisco Bay Area between June 1984 and August 1985, killing at least fourteen people and committing numerous sexual assaults and other violent crimes. Ramirez had no consistent victim profile: he attacked men, women, children, and elderly people; he broke into homes at night through unlocked windows and doors; he used guns, knives, hammers, and a tire iron. He left pentagrams at crime scenes and sometimes forced survivors to "swear to Satan." The press named him "the Night Stalker," a title that reflected the reign of terror he imposed on an entire region. The investigation spanned multiple jurisdictions and involved a collaborative task force. The breakthrough came after Ramirez committed a final assault in Mission Viejo on August 24, 1985, during which a surviving witness sketched his face from memory. His name came from fingerprints matched to prior criminal records; his photograph was published widely. On August 31, 1985, Ramirez arrived in East Los Angeles after a bus trip from Phoenix, where he had been out of state during the media frenzy. Recognized by community members in a store, he was chased, caught, and beaten by a crowd before police arrived to take him into custody. Ramirez was charged with thirteen counts of murder, five counts of attempted murder, eleven sexual assaults, and numerous other crimes. His trial — delayed repeatedly — was a spectacle: Ramirez flashed pentagrams to the courtroom, threatened and intimidated witnesses, and attracted a fan following of women who sent him love letters. He was convicted on all nineteen counts of murder and attempted murder in 1989 and sentenced to death nineteen times over. He remained on California's death row for over two decades, becoming one of its longest-serving condemned inmates. Richard Ramirez died of natural causes — B-cell lymphoma — on death row at San Quentin State Prison on June 7, 2013, at age fifty-three, without ever facing execution. He had married a fan and journalist, Doreen Lioy, in a prison ceremony in 1996, though she reportedly separated from him after DNA evidence confirmed additional crimes. The Night Stalker's murders remain among the most disturbing in California history, a case that reshaped security consciousness in the suburban sprawl of Los Angeles and left psychological trauma in communities throughout Southern California.
