From 1976 to 1986, a serial killer now known as the Golden State Killer committed a staggering number of crimes in California ranging from burglaries to rapes to 12 known homicides. Like the Zodiac killer, the individual’s ability to escape detection and capture led to a public fascination over the decade-long spree. Now, it appears authorities may have finally closed in on the person responsible.

According to The Daily Beast, Sacramento police are expected to announce Wednesday afternoon that an arrest has been made in connection with the 120 burglaries, 45 sexual assaults, and murders that ended more than 30 years ago. Joseph James DeAngelo, 72, has reportedly been arrested on two counts of murder, with authorities expected to confirm he is a suspect in the Golden State Killer cases. DeAngelo is a former police officer who worked just outside of Sacramento in the 1970s.

The Golden State Killer is the topic of a recent best-selling true crime book, Michelle McNamara’s I’ll Be Gone in the Dark: One Woman's Obsessive Search for the Golden State Killer. McNamara, who spent five years researching the case, passed away suddenly in 2016, when she was only halfway done with the project. Her husband, comedian/actor Patton Oswalt, hired investigative reporter Billy Jensen to complete her work. The book, which is currently being turned into an HBO docuseries, is being credited with renewing both public and law enforcement interest in the case, which may have led to DeAngelo’s arrest.

The killer was active in the Sacramento suburbs of Rancho Cordova and Carmichael, as well as other parts of Southern California. He was also given the labels East Area Rapist, the Original Night Stalker, and the Diamond Knot Killer. His last suspected crime was the murder of an 18-year-old girl in Irvine, California in 1986.
