A police officer in Texas is being hailed as a hero after he revived a child who had stopped breathing. A police officer responded to a KFC in the town of Granbury seconds after a father called 911 to report that his son wasn’t breathing, and found a 3-year-old boy being clutched by a sobber mother shouting his name, Brayden.

The child was unresponsive, and Officer Chase Miller took him from his arms and immediately started CPR as paramedics headed to the scene. A dash cam of the encounter was uploaded to YouTube by the city of Granbury, showing Miller pulling into the parking lot to see the traumatic scene.

Miller told NBC-DFW that he was “just trying to get him breathing,” and that nothing else mattered at that point.

The officer was calm during the ordeal, even having the father continue CPR as he retrieved a CPR mask from his patrol car.

“He responded exactly like we would hope an officer would respond,” Deputy Granbury Police Chief Jim Marshall said according to a Washington Post report. “He was calm, and I truly believe that his calm demeanor helped stabilize the parents a little bit. At one point, he needed the father to take over chest compressions while he returned to his patrol vehicle.”

He added: “Officer Miller knew from his training that the child would need a breathing mask to survive.”

Miller performed CPR for about three minutes, and the boy started breathing again. He made a full recovery at the hospital later. Authorities believe he suffered from seizure and high fever.
