Kelly Thomas (April 5, 1974 – July 10, 2011) was a homeless man diagnosed with schizophrenia who lived on the streets of Fullerton, California. He died five days after being severely beaten by six members of the Fullerton Police Department whom he encountered on July 5, 2011, in what was later described as "one of the worst police beatings in [US] history." Medical records show that bones in his face were broken and he choked on his own blood. The coroner concluded that compression of the thorax made it impossible for Thomas to breathe normally and deprived his brain of oxygen. Officer Manuel Ramos was charged with one count of second-degree murder and one count of involuntary manslaughter; Corporal Jay Cicinelli and Officer Joseph Wolfe were each charged with one count of felony involuntary manslaughter and one count of excessive force. All three pleaded not guilty. A judge declined to dismiss the charges against the officers in January 2013, finding that "a reasonable person could infer that the use of force was excessive and unreasonable." An appeals court judge also denied a request to overturn the lower court's decision. On January 13, 2014, Ramos and Cicinelli were found not guilty of all charges, while the trial for Wolfe was pending. Following the verdict for the two officers, the district attorney's office announced it would not pursue the case against Wolfe. On January 17, 2014, charges against Wolfe were dropped.

The incident motivated various changes in the treatment of homeless and mentally ill persons in Fullerton and elsewhere in California. Background Kelly Thomas was born April 5, 1974, to Ron Thomas, a former Orange County Sheriff's deputy, and Cathy Thomas. Thomas, who was diagnosed with schizophrenia, was a "fixture" among Fullerton's homeless population. The death of Thomas has sparked debate about systemic reforms in treatment of the mentally ill. Between 1990 and 2011, Thomas had 92 encounters with the police. These encounters ranged from minor infractions such as trespassing to a guilty plea in an assault with a deadly weapon case sixteen years prior. Manuel Ramos, one of the police officers who would later be arrested on murder charges for his beating of Thomas, had been put on a
