The Murders and Rapes: A Chronology
Joseph DeAngelo's crimes spanned over a decade, evolving from burglaries to rapes and murders across California. His tactics became increasingly violent as he moved from Northern to Southern California.
Early Crimes in Sacramento
DeAngelo's crime spree began in the mid-1970s in Sacramento County. He initially focused on burglaries, earning the moniker "Visalia Ransacker" for his meticulous searching of homes.
In 1976, his crimes escalated to sexual assaults. DeAngelo targeted women alone or with children, often when their partners were away. He used sophisticated tactics, including pre-attack surveillance and cutting phone lines.
By 1977, DeAngelo had committed at least 20 rapes in the Sacramento area. His victims ranged from teenagers to women in their 30s.
The East Area Rapist in Northern California
As the "East Area Rapist," DeAngelo's attacks intensified. He expanded his territory to include Contra Costa County and the San Francisco Bay Area.
Between 1978 and 1979, DeAngelo committed his first known murders. On February 2, 1978, he killed Brian and Katie Maggiore in Rancho Cordova.
His modus operandi evolved to include couples. DeAngelo would tie up the male victim before assaulting the female. He often lingered in victims' homes, sometimes eating their food or stealing small items.
Southern California and the Original Night Stalker
In 1979, DeAngelo's crimes shifted to Southern California. Now known as the "Original Night Stalker," his attacks became even more violent.
Between 1979 and 1986, he committed at least 7 murders in Santa Barbara, Ventura, and Orange counties. His victims included:
Robert Offerman and Debra Manning (December 30, 1979)
Charlene and Lyman Smith (March 13, 1980)
Keith and Patrice Harrington (August 19, 1980)
DeAngelo's final known murder was of Janelle Cruz in Irvine on May 4, 1986. After this, his crime spree appeared to stop abruptly.
Profile of a Killer
Joseph James DeAngelo's path to becoming the Golden State Killer involved early life experiences, a series of crimes as the Visalia Ransacker, and a career in law enforcement. These elements shaped the man who would terrorize California for over a decade.

The Ransacker's modus operandi included:
Stealing small items and ransacking homes
Scattering women's undergarments
Leaving coins and jewelry behind
These behaviors foreshadowed the more violent crimes DeAngelo would later commit as the Golden State Killer.
A Former Police Officer
DeAngelo's career as a police officer provided him with insider knowledge of law enforcement techniques. He served in Exeter, California from 1973 to 1976, coinciding with the Visalia Ransacker crimes.
Later, he worked for the Auburn Police Department from 1976 to 1979. His termination for shoplifting aligned with the start of the East Area Rapist series in the Sacramento area.
DeAngelo's law enforcement background gave him:
Understanding of police procedures
Access to information about investigations
Skills to avoid detection
This unique position allowed him to commit crimes while hiding in plain sight for decades.
The Cold Case Heats Up
The Golden State Killer case remained unsolved for decades until innovative DNA techniques and genealogy research led to a breakthrough. Investigators utilized cutting-edge genetic technology to identify the elusive perpetrator.
Genealogy and DNA
DNA evidence collected from crime scenes proved crucial in the hunt for the Golden State Killer. Investigators had a genetic profile but no match in criminal databases. They turned to genetic genealogy, a method combining DNA analysis with traditional genealogical research.
This approach uses DNA to find relatives of an unknown person, then builds family trees to identify potential suspects. The technique raised privacy concerns, as it involved searching public genealogy databases containing genetic information from individuals not suspected of crimes.
The Breakthrough of Genetic Genealogy
In 2018, investigators uploaded the Golden State Killer's DNA profile to GEDmatch, a public genealogy database. They found distant relatives and constructed extensive family trees.
This painstaking process narrowed the search to a small group of individuals. Ethical debates arose about the use of genetic data without consent for law enforcement purposes. However, the potential to solve cold cases outweighed privacy concerns for many.
Arrest and Identification
The genetic genealogy investigation led authorities to Joseph James DeAngelo, a former police officer living in Sacramento. Investigators secretly collected DeAngelo's DNA from a discarded item and compared it to crime scene evidence.
The match confirmed DeAngelo as the Golden State Killer. On April 24, 2018, police arrested the 72-year-old at his home. The arrest marked a significant victory for cold case investigators and showcased the power of genetic technology in solving decades-old crimes.
DeAngelo's capture reignited discussions about genetic privacy and the need for clearer regulations on using DNA databases for law enforcement purposes.
The Path to Justice
Joseph DeAngelo's arrest in 2018 marked the beginning of a complex legal process. The proceedings brought long-awaited closure to victims and their families, culminating in DeAngelo's sentencing and imprisonment.
Legal Proceedings
DeAngelo faced charges for 13 murders and numerous rapes across California. The Sacramento County District Attorney's office led the prosecution, collaborating with multiple jurisdictions.
DeAngelo initially pleaded not guilty. However, in June 2020, he changed his plea to guilty for 13 counts of first-degree murder and 13 counts of kidnapping to commit robbery.
The plea deal spared DeAngelo the death penalty but ensured he would never be released from prison.
Sentencing and Life in Prison
On August 21, 2020, DeAngelo received multiple life sentences without the possibility of parole. The judge imposed 11 consecutive life terms plus an additional 8 years.
DeAngelo's confinement began at North Kern State Prison for processing. He was later transferred to a protective housing unit at California State Prison, Corcoran.
The facility houses infamous inmates and those requiring special protection. DeAngelo's daily life is heavily restricted, with limited contact and activities.
