The brutal beating of Kelly Thomas has two Fullerton, California police officers potentially facing second-degree murder and involuntary manslaughter charges. Thomas, a homeless schizophrenic man, was brutally beaten to death by officers Manuel Ramos and Jay Cicinelli in July of 2011. Thomas died five days later after he was taken off life support and much of the evidence against the two officers is on video tape recorded by witnesses.
