The Brutal Crime Against Mary Vincent and the 14-Year Sentence
The crime that cemented Larry Singleton's place in the annals of true crime occurred on September 29, 1978. Singleton, a former merchant seaman, picked up 15-year-old Mary Vincent, a hitchhiker traveling from Berkeley to Las Vegas.
He drove her to a remote area near Modesto, California, where he brutally raped her.
In a final, horrific act of depravity, Singleton took an axe and chopped off both of Mary Vincent's forearms to prevent her from identifying him, before leaving her for dead in a drainage culvert.
The details of the crime were so gruesome that they immediately captured national attention.
The Survivor's Unthinkable Resilience
Despite being left to bleed out, Mary Vincent exhibited extraordinary courage and resilience.
Bleeding profusely from her severed arms, she managed to crawl 30 feet up an embankment to the side of the road, where she was eventually discovered and rushed to a hospital.
Her ability to survive and, crucially, to later identify Singleton was a powerful testament to the human will.
Singleton was convicted in 1979 of kidnapping, rape, and attempted murder.
Due to California's determinate sentencing law at the time, which limited the maximum sentence for his crimes, Singleton was sentenced to only 14 years and 4 months in state prison.
This sentence, considered shockingly lenient for the severity of the crime, became a major source of public anger and a rallying cry for judicial reform.
The Unprecedented California Parole Crisis of 1987
When Larry Singleton became eligible for parole in 1987, having served only about eight years of his sentence, a massive public and political crisis erupted.
The prospect of a convicted rapist and mutilator being released back into society sparked a wave of "Not In My Town" protests across Northern California.
Community sentiment against his placement was overwhelmingly negative, demonstrating the powerful impact of fear of crime on parole decisions.
Sheriffs, city councils, and neighborhood groups in multiple counties—including Contra Costa County, Solano County, and others—vowed to prevent Singleton from being housed in their jurisdictions.
The state's attempt to find a suitable parole location became a month-long, nationally covered saga.
Frustrated by the widespread community refusal, then-Governor George Deukmejian took the unprecedented step of ordering Singleton to be housed at a temporary trailer on the grounds of San Quentin State Prison, an active correctional facility.
This move was highly unusual, as parolees are typically released into the community.
The "Singleton Shuffle," as the constant moving of the parolee was dubbed, highlighted a fundamental flaw in the parole system and led to a serious re-evaluation of how violent offenders are released.
Lawrence Singleton's Final Years and Death
After his controversial parole in California, Larry Singleton eventually moved to the Tampa Bay area of Florida.
In 1997, his criminal career tragically continued.
Singleton was arrested and convicted of the second-degree murder of Roxanne Hayes, a prostitute.
This subsequent conviction, which occurred 19 years after the attack on Mary Vincent, confirmed the fears of the California communities that had protested his release.
He was sentenced to life in prison in Florida.
Lawrence Bernard "Larry" Singleton died in a Florida prison on December 28, 2001, at the age of 74, due to cancer.
His death closed a chapter on one of the most infamous true crime cases in American history, but the legal and social questions raised by his parole continue to influence policy and public safety debates today.
The Enduring Legacy of the Singleton Case
The case of Lawrence Singleton and Mary Vincent had a profound and lasting impact on the American judicial system and public consciousness:
- Parole Reform: The intense public backlash against Singleton's release led to calls for and eventual changes in parole procedures, particularly regarding the placement and monitoring of highly dangerous sex offenders.
- Victim Advocacy: Mary Vincent became a powerful, albeit reluctant, symbol of survival. Her courage in identifying her attacker and rebuilding her life—learning to use prosthetic arms—inspired countless others.
- Determinate Sentencing Debate: The case was often cited by critics of California's determinate sentencing law, arguing that it failed to adequately punish and incapacitate the most violent criminals.
- Community Safety: The "Not In My Town" movement associated with his parole was a landmark example of community sentiment overriding standard bureaucratic procedures, forcing the state to address public safety concerns in a new way.
- True Crime Interest: The horrific nature of the crime and the subsequent legal drama ensure that the case remains a frequent subject of true crime documentaries, podcasts, and articles, keeping the memory of Mary Vincent’s survival and Singleton’s brutality alive.
The story of Lawrence Singleton is a dark narrative of cruelty, but it is equally a story of Mary Vincent's extraordinary strength, a reminder that even in the face of unspeakable violence, the human spirit can endure and triumph.
