The Dallas County Sheriff's Office has identified the suspect in the Cedar Hill officer-involved shooting that left one man and three police officers injured.
The suspect in the case is 27-year-old Terrance Dunn according to the sheriff's office.
Cedar Hill police said Dunn ran from them while setting himself on fire Wednesday afternoon in Cedar Hill.
Surveillance video released Thursday shows how neighbors rushed to help Cedar Hill police officer Ann McSwain who was set on fire during the incident.
The surveillance video was shot from inside a MetroPCS store beside the Wingstop restaurant.
Officer McSwain was severely burned in the attack and is currently in serious condition at Parkland Hospital.
Dunn, was suspected in a nearby burglary when officers pursued him into the Wingstop restaurant at US 67 and Belt Line Road in Cedar Hill and tried to subdue him about 3 p.m. Wednesday, Cedar Hill Police Lt. Charles Reiss said.
Armed with a bottle of flammable liquid, Dunn set himself ablaze. Witnesses said Officer Ann McSwain carried a stun gun as the man yelled, "I have gas. I have gasoline. I'm gonna catch myself on fire."
The suspect, who reeked of gasoline and was holding a bottle of flammable liquid, set himself and the female officer on fire, Reiss said. Witnesses rushed to help officer McSwain.
The other officers chased the blazing suspect and tried to smother his flames, before one officer finally shot the man, Brown said. Aside from the bottle, a yellow lighter was found at the scene, Cedar Hill city spokesman Corky Brown said.
Officer McSwain was airlifted with serious burns to Parkland Memorial Hospital in Dallas, according to Brown. Detective Mike Hernandez and detective Brandon Woodall were treated for burns and released from Parkland Hospital Wednesday night.
