Sacramento County detective, original EAR investigator
Richard Shelby was a Sacramento County Sheriff's detective who was one of the original investigators on the East Area Rapist case in the late 1970s. He authored "Hunting a Psychopath," detailing the investigation and the frustrations of trying to catch a serial offender who seemed to know police procedures. Shelby came agonizingly close to identifying DeAngelo during the original investigation — DeAngelo was briefly considered as a suspect due to his law enforcement background but was not pursued.

Background
Introduction to Richard Shelby
Richard Shelby is a retired Sacramento County Sheriff's detective who played a pivotal role in the original investigation of the East Area Rapist (EAR), later identified as the Golden State Killer, Joseph DeAngelo. Active during the late 1970s, Shelby was among the first law enforcement officers to pursue the serial offender responsible for a series of rapes, burglaries, and eventually murders across California. His dedication to the case spanned years, marked by both significant breakthroughs and frustrating dead ends, as detailed in his book, Hunting a Psychopath, which provides an in-depth account of the early investigation.
Role in the East Area Rapist Investigation
As a lead detective in Sacramento County during the East Area Rapist attacks from 1976 to 1979, Shelby was instrumental in documenting the offender’s patterns and attempting to predict his movements. The EAR was notorious for meticulous planning, often evading capture through an apparent understanding of police tactics. Shelby’s work focused on connecting crime scenes, interviewing victims, and analyzing the offender’s behavior, which included stalking neighborhoods and targeting middle-class homes. One of the most notable aspects of Shelby’s involvement was his suspicion of individuals with law enforcement backgrounds, given the suspect’s ability to avoid detection. During the investigation, Joseph DeAngelo, who was a police officer at the time, was briefly considered a suspect due to this profile. However, DeAngelo was not pursued further, a decision that Shelby later reflected on with frustration in his writings.
Shelby’s book, Hunting a Psychopath, published in 2014, offers a firsthand perspective on the challenges faced by investigators, including limited technology and inter-agency coordination issues. His accounts highlight the psychological toll of pursuing a predator who terrorized communities for years without being apprehended during the initial investigation.
Significance and Legacy
Richard Shelby’s contributions to the Golden State Killer case remain significant, even though the breakthrough in identifying DeAngelo came decades later through forensic genealogy in 2018. His early work laid the groundwork for understanding the offender’s methods, which later helped link the EAR crimes to the Original Night Stalker series in Southern California. Shelby’s documentation of the case also serves as a historical record of one of the most complex serial offender investigations in U.S. history.
While Shelby did not work directly with later investigators like Paul Holes, who spearheaded the DNA-based identification of DeAngelo, his insights and persistence influenced the collective effort to solve the case. His story underscores the perseverance of law enforcement in the face of seemingly insurmountable challenges and the eventual triumph of justice through evolving forensic science.
