A man told police that one of his roommates pistol whipped him after accusing him of "eating the whole pot roast."
Robert "Cooter Brown" Cooper, 66, is charged with attempted first-degree murder and aggravated assault.
Glenn Davis walked up to officers at the Krystal on Cherokee Boulevard and told them about the incident on Saturday.
He said he was sleeping when Cooper started hitting him with the weapon.
He said he grabbed the gun and pushed it toward the floor, then they struggled over it and the magazine dropped to the floor. He said Cooper told him, "That's okay. Still have one in the chamber."
The third roommate, M.C. Eddings, then grabbed the gun and was able to eject the final round.
