Paul Raymond Cavanaugh, aged 31, was found dead on November 27, 1984, on Roberts Island, California. His death was a result of a violent crime, as he was shot to death alongside Howard King, another victim. The bodies of both men were discovered beside a car on a remote road on Roberts Island. This tragic event was part of a series of murders committed by the notorious "Speed Freak Killers," Loren Herzog and Wesley Shermantine.
These two individuals were responsible for a string of killings in the San Joaquin County area during the 1980s and 1990s.
The investigation into Cavanaugh's death revealed that he and King were drifters who fell victim to the Speed Freak Killers' spree. Herzog and Shermantine, who were childhood friends and known for their methamphetamine abuse, embarked on a killing spree that claimed numerous lives. The duo's criminal activities included robbery and murder, and they were eventually apprehended in 1999. The case against them was built on a combination of physical evidence and confessions, leading to their convictions.
In 2001, a jury found Wesley Shermantine guilty of multiple murders, including the deaths of Paul Raymond Cavanaugh and Howard King. Shermantine was sentenced to death and remains on death row at San Quentin State Prison. Loren Herzog, on the other hand, faced a different fate. Initially convicted of several murders, his convictions were later overturned, and he was released on parole. However, Herzog committed suicide in 2012, bringing an end to his involvement in the case.
The legal proceedings surrounding the Speed Freak Killers were complex and spanned several years. The prosecution faced challenges in consolidating multiple murder cases from different jurisdictions, but the enactment of a new "serial killer" statute allowed for a more streamlined approach. This statute enabled the consolidation of cases, ultimately leading to the successful prosecution of Shermantine and Herzog. The case remains a significant chapter in California's criminal history, highlighting the dangers posed by serial killers and the relentless pursuit of justice by law enforcement agencies.
