Who Is the Golden State Killer
The Golden State Killer is the nickname for Joseph James DeAngelo Jr., a former police officer linked to a series of violent crimes across California. He committed at least 13 homicides, 50 rapes, and over 100 burglaries between 1974 and 1986.
Crimes, Investigation, and Capture
Investigators linked the crimes through DNA and behavioral patterns, but the case went cold for decades. In 2018, authorities used forensic genealogy, uploading crime-scene DNA to public databases to identify a relative of the suspect. This led to DeAngelo’s arrest and a subsequent guilty plea.
Conviction, Sentencing, and Legacy
In 2020, DeAngelo pleaded guilty to multiple counts of murder and kidnapping and was sentenced to life in prison without parole. The case is widely cited as a landmark in the use of genetic genealogy for criminal investigations.
