In the late hours of a November evening in 1996, a domestic dispute in Cassville, Missouri, set in motion a chain of events that would end in tragedy. Responding to a call about a suspicious vehicle, 29-year-old Barry County Sheriff's Deputy Christopher Lee Castetter, a male, arrived at the scene, unaware of the violence that awaited him. As he pulled up, the occupant of the vehicle, Cecil Clayton, opened fire, striking the deputy in the head.
Deputy Castetter was rushed to a medical center in Springfield but succumbed to his injuries the following day, November 28, 1996.
The investigation swiftly led to the identification and arrest of Cecil Clayton. The motive appeared to be linked to an earlier argument Clayton had with his girlfriend. In the aftermath of the shooting, it was reported that Clayton had confided in a friend about what he had done and had attempted to create an alibi. These actions suggested an awareness of his crime, a point that would become a significant factor in the legal proceedings that followed.
In June of 1999, a jury found Cecil Clayton guilty of the first-degree murder of Deputy Castetter and recommended a sentence of death. During the legal process, Clayton's defense attorneys raised concerns about his mental state, citing a sawmill accident in 1972 that resulted in the removal of a portion of his brain's frontal lobe. They argued that this injury had altered his personality and rendered him mentally incompetent. Despite these arguments and numerous appeals, the courts upheld the conviction and sentence. After years on death row, Cecil Clayton was executed by lethal injection in March of 2015.
