Police said Monday the victim heard a loud bang and got hit by something when the shooting occurred Sunday at the Mesa Inn.
Officers said they found a large hole in the wall and arrested 26-year-old Zachariah McCullough on suspicion of prohibited use of a weapon, illegal discharge of a firearm, reckless endangerment, and assault.
Police say they believe McCullough was in an adjacent room and was handling a large revolver when the gun went off.
