Mary Vincent, at the age of 15, survived a horrific assault where a man severed both her arms and abandoned her in a ravine to perish. In 1978, while hitchhiking to her grandfather’s house after leaving home, she encountered a seemingly friendly older man in a blue van who offered her a ride. Despite initial reluctance, she accepted, leading to a tragic turn of events.
The man, identified as 51-year-old Lawrence Singleton, a former merchant seaman, took Mary to a remote area near Modesto, California, initiating a harrowing ordeal. Singleton rendered Mary unconscious, removed her clothing, and restrained her before subjecting her to multiple sexual assaults while disregarding her pleas for release over several hours.
The following morning, Singleton callously severed both of Mary’s arms with a hatchet, dumped her in a ravine, and left her for dead. Miraculously, Mary clung to life, driven by an inner voice urging her to stay awake and prevent further harm to others. With exceptional resilience, she filled the injuries with dirt to stem the bleeding, climbed out of the ravine, and flagged down a passing vehicle despite her naked, injured, and weakened state.
Good Samaritans found Mary wandering nude the next day and rushed her to a nearby hospital. With the help of a forensic sketch artist and Mary’s description, authorities captured Singleton, who was convicted of seven felonies, including attempted murder, rape, and kidnapping. He received a 14-year prison sentence, the maximum allowed by law at the time in California, and was granted parole after serving slightly over eight years.
Public outrage following his release led to Singleton’s relocation and eventual parole supervision near San Quentin Prison, as no community in Northern California would accept him. Tragically, in 1997, nearly two decades after his attack on Mary, Singleton murdered Roxanne Hayes in Tampa, Florida, leading to his death sentence, which he didn’t serve entirely due to dying from cancer in 2001.
Mary Vincent, despite enduring ongoing nightmares, dedicated herself to advocating for change. She shared her story with trauma survivors, testified before legislative bodies, and played a crucial role in the passing of the “Singleton bill” in California. This law increased the maximum penalty for crimes similar to those committed by Singleton, reflecting Mary’s unwavering commitment to justice and reform.
