The Golden State Killer was Joseph James DeAngelo Jr., a former police officer who became one of America's most notorious serial criminals, terrorizing California for over a decade between 1974 and 1986. He was responsible for at least 13 murders, more than 50 rapes, and over 120 burglaries across the state, operating under several different monikers before DNA evidence finally linked all the crimes to a single perpetrator.

The Terrifying Crime Spree

DeAngelo's criminal activity evolved over time, becoming increasingly violent as the years progressed. His reign of terror unfolded in distinct phases across California:

  • The Visalia Ransacker (1974-1975): He began with 120 burglaries in a small three-mile area in Visalia, stealing small trophies and going through women's underwear drawers. In 1975, he attempted to kidnap a teenage girl, and when her father intervened, he killed him.
  • The East Area Rapist (1976-1979): Starting in June 1976 in Sacramento County, he assaulted more than 40 women in northern California. His attacks spread to Stockton, Modesto, San Jose, and Contra Costa County. In 1978, he shot and killed a Sacramento County couple who had been walking their dog.
  • The Original Night Stalker (1979-1986): The crimes escalated to a series of murders in southern California. He would often attack couples, tying up both victims, raping the female, and then murdering them. His last confirmed victim was 18-year-old Janelle Cruz, who was killed in Orange County in 1986.

The Dark Double Life

What makes DeAngelo's case particularly chilling is that he was a police officer while committing many of these crimes. He worked as a police officer in a neighboring town and was even part of the task force assigned to catch the Visalia Ransacker—while he himself was the perpetrator. His law enforcement experience gave him insider knowledge of police procedures, response times, and evasion techniques, which he exploited to commit his crimes and escape detection.

The Decades-Long Hunt

For decades, authorities had no idea these crimes were connected or who was responsible. In 2001, DNA analysis revealed that the rapes and murders had been committed by the same person. Crime writer Michelle McNamara coined the name "Golden State Killer" to describe this unknown perpetrator. The case remained cold until advanced genealogical DNA technology finally cracked it open in 2018.

Investigators used DNA from a crime scene, converted it into a genetic profile, and uploaded it to genealogy websites to find distant relatives. They built a massive family tree with about a thousand names and worked to narrow down suspects. This groundbreaking investigative technique led them directly to Joseph DeAngelo.

Justice Finally Served

DeAngelo was arrested in April 2018 at age 72. Born on November 8, 1945, in Bath, New York, he had managed to evade capture for over 40 years. In June 2020, he pleaded guilty to 13 counts of first-degree murder, and in August 2020, he was sentenced to life in prison without the possibility of parole. During his sentencing, DeAngelo addressed the court, saying "I'm truly sorry".

Prosecutor Thien Ho, who led the case, later wrote a book detailing DeAngelo's "insatiable appetite for power" that drove his violent crimes, suggesting he had no power in his personal life. Survivors confronted DeAngelo in court, with many identifying themselves by their victim numbers, creating powerful moments of accountability.

Unanswered Questions Remain

Prosecutors acknowledge there may be more victims that haven't been linked to DeAngelo. There's a mysterious three-year gap from 1986 to 1989 where his whereabouts and actions remain uncertain, leading investigators to wonder if he continued committing crimes that were never discovered. The full scope of his criminal activity may never be completely known.

TLDR: The Golden State Killer was Joseph James DeAngelo, a former police officer who terrorized California from 1974 to 1986 with over 120 burglaries, 50+ rapes, and 13 murders. He evaded capture for four decades until genealogical DNA technology led to his arrest in 2018. He pleaded guilty in 2020 and is now serving life in prison without parole.
