Executive Summary
Joseph James DeAngelo is a prolific American serial killer, rapist, and burglar who committed at least 13 murders, 51+ rapes, and 120+ burglaries across California. A former police officer, DeAngelo utilized his tactical training to evade capture for over 40 years until his arrest in April 2018 via investigative genetic genealogy.
Geographic Profile & Modus Operandi
DeAngelo’s crime spree is characterized by three distinct phases:
- Visalia Ransacker (1974–1975): Early escalation involving fetishistic burglaries and the murder of Claude Snelling.
- East Area Rapist (1976–1979): Concentrated attacks in Sacramento and Northern California, often targeting suburban homes near greenways and canals for easy escape.
- Original Night Stalker (1979–1986): Transition to Southern California, where the crimes escalated to brutal homicides of couples and individuals.

Investigative Analysis
- Professional Background: DeAngelo served as a police officer in Exeter (1973–1976) and Auburn (1976–1979), providing him with knowledge of police procedures, perimeter control, and evidence evasion.
- Tactical Signatures:
- Pre-attack stalking and home prowling.
- Using “warning items” (dishes/bottles) on door handles to alert him to movement.
- Tying up male victims and placing plates on their backs while assaulting female victims.
- Taking small, sentimental items (e.g., single earrings) as trophies.
- Identification: Captured using Investigative Genetic Genealogy (IGG), which matched crime scene DNA to distant relatives on public genealogy databases.
In 2020, as part of a plea agreement to avoid the death penalty, Joseph James DeAngelo admitted to a total of 161 uncharged crimes. These offenses involve 61 additional victims and occurred in 11 different California counties.
Because many of these crimes were committed during his “East Area Rapist” and “Visalia Ransacker” phases in the 1970s, they could not be formally charged due to the statute of limitations.
Phase 1: The Visalia Ransacker (1974–1975)
During this period, DeAngelo was a police officer in Exeter. He admitted to approximately 120 burglaries and ransackings in Tulare County.
- Target Area: Visalia, CA (Approx. 36.3302° N, 119.2921° W)
- Activity: Entering homes to vandalize possessions, rearranging personal items, and stealing low-value trophies (stamps, single earrings, medallions) rather than cash.
- Escalation: He admitted to the attempted kidnapping and murder of Claude Snelling (Sept 11, 1975) during this phase.
Phase 2: The East Area Rapist (1976–1979)
This is the most concentrated period of uncharged sexual assaults. DeAngelo admitted to at least 51 rapes across Northern and Central California.
| Date Range | Primary Location | Type of Admissions |
| 1976–1977 | Sacramento County (Rancho Cordova, Carmichael) | 23+ Rapes, Kidnappings, and Robberies |
| Sept 1977 | Stockton, San Joaquin County | Multiple Rapes & Burglaries |
| Oct–Dec 1977 | Sacramento (Arden-Arcade, Foothill Farms) | Continued Sexual Assaults |
| Jan–July 1978 | Modesto, Davis, & Stockton | Expansion to Yolo and Stanislaus Counties |
| Oct–Dec 1978 | Concord, San Ramon, San Jose | Expansion to Contra Costa & Santa Clara Counties |
| April–July 1979 | Fremont, Walnut Creek, Danville | Final EAR-style attacks in Alameda/Contra Costa |
Phase 3: The Original Night Stalker (1979–1986)
While most Southern California incidents resulted in murder charges, DeAngelo admitted to several uncharged burglaries and attempted murders that served as “prowling” precursors to his homicides.
- Goleta (1979): Admitted to several burglaries and a failed attack on a couple that preceded the Offerman-Manning murders.
- Psychological Profile: During his confession, he admitted to an internal “alter ego” he called “Jerry,” whom he claimed forced him to commit these acts.

- Tulare County: 120+ burglaries, as the Visalia Ransacker.
- San Joaquin & Stanislaus Counties: Attacks in Stockton and Modesto.
