Coy Wayne "Elvis" Wesbrook (February 1, 1958 – March 9, 2016) was an American mass murderer, convicted for the killing of five people in Channelview, Texas on November 13, 1997. Wesbrook fatally shot his ex-wife Gloria Jean Coons, her female roommate, and three men during a party at Coons' home in an apparent fit of jealous rage.

Wesbrook was sentenced to death in 1998, and was executed by lethal injection in 2016.[1] The case was controversial due to questions about Wesbrook's intelligence being low enough that a death sentence was improper.
