Gerald Earl Cavanagh, a 49-year-old Canadian-American man, was found dead at the water’s edge on San Francisco’s Ocean Beach in the early hours of January 27, 1974. His body bore multiple stab wounds, including a defensive wound on his left hand, indicating that he had attempted to resist his attacker. At the time of his death, Cavanagh was fully clothed, wearing underwear, shoes, socks, pants, a shirt, and a jacket. He had $21.12 in his pocket and a Timex watch on his wrist.
Initially unidentified, he was temporarily referred to as "John Doe #7" by the medical examiner.
Cavanagh was the first known victim in a series of homicides attributed to an unidentified serial killer known as "The Doodler." This perpetrator, believed to be a Black man between 19 and 25 years old, was known for sketching his victims before stabbing them to death. The killings, which occurred between January 1974 and September 1975, primarily targeted white males who had met the suspect at gay nightclubs, bars, and restaurants in San Francisco. The victims were often found in waterfront areas or parks, stabbed in similar locations on their bodies.
Despite investigations, the case remains unsolved. Authorities suspected that the victims had died after meeting with the suspect near the locations where their bodies were recovered. Cavanagh’s murder was followed by several others, including Joseph "Jae" Stevens, a 27-year-old entertainer, and Klaus Achim "Claus" Christmann, a 31-year-old German-American immigrant. Christmann’s murder was particularly violent, with multiple stab wounds and deep slashes to the throat. The police theorized that Christmann may have been a closeted gay man, as he was found with a makeup tube in his possession.
Over the years, law enforcement has struggled to definitively link all the murders to The Doodler, as the number of victims varies between reports. Some sources credit the killer with up to 16 murders, while others suggest a lower count of five or six. The case did not receive widespread media attention at the time, possibly due to societal attitudes toward homosexuality. Unlike other serial killings, such as those committed by the Zodiac Killer or David Berkowitz, The Doodler murders faded into obscurity.
Despite renewed interest in cold cases, no arrests have been made in connection with Cavanagh’s murder or the broader series of killings. The identity of The Doodler remains unknown, and the case continues to be one of San Francisco’s most perplexing unsolved crimes.
