Patrick Gray Sharp, 29, the gunman who opened fire Tuesday on a suburban Dallas police station, committed suicide, the Collin County Medical Examiner's Office said Wednesday.
Sharp died of a self-inflicted gunshot wound to the head, the medical examiner’s office said.
Records show that Sharp was licensed in 2004 by the Texas Department of Public Safety to work as a security guard and that three years earlier, he was certified as a jailer by the Texas Commission on Law Enforcement Officer Standards and Education, The Associated Press reported Wednesday.
Sharp drove his truck, towing a trailer, into the parking lot of the McKinney Police Department building Tuesday and set the truck on fire.
Then he opened fire.
McKinney police Chief Doug Kowalski said he had a plan and was heavily armed.
Investigators recovered an assault rifle, a shotgun and a handgun.
Sharp fired at least 100 rounds at the police station, and the chief counted at least 23 bullet strikes on the building.
Bullets also struck a building on the nearby Collin Community College campus, which was locked down because of the shootout.
Kowalski said Sharp may have set the fire to draw people out of the building so he could shoot them.
Kowalski said the trailer failed to ignite, however.
Sharp's roommate, Eric McClellan, told The Associated Press by phone that he was on vacation outside Texas when he received calls from Department of Public Safety troopers and his stepfather telling him what happened.
McClellan, who left Texas earlier this week, said Sharp was "fine and dandy" when he departed.
