On December 15, 1998, Mathis shot three victims in the head with a .45 caliber pistol at a known drug house in Ft. Bend County, Texas. One of the victims, a 15-year-old girl survived the shooting, paralyzed from the chest down. Mathis reportedly turned the gun on two other intended victims, however when he attempted to pull the trigger the gun either misfired or jammed.
