Pablo Ruiz, a 43-year-old San Antonio man, was drinking with friends during a Fourth of July celebration when he decided to light a mortar-type firework above his head, the Fort Worth Star-Telegram reported. The firework exploded from the bottom and pierced the top of his skull, killing him almost instantly, police told the newspaper. San Antonio police officers arrived at the residential area shortly after midnight. Ruiz suffered severe head trauma with brain matter exposed from his skull. The man died a short time later and was later identified by the Bexar County Medical Examiner’s Office.
