() Nearly 30 years after the bombing outside a federal building in Oklahoma City, a retired firefighter who responded to the scene is sharing his story to help other first responders navigate the trauma they face on their jobs.

On April 19, 1995, a truck bomb exploded in front of the Alfred P. Murrah federal building just after 9 a.m., killing 168 people, including 19 children, and injuring more than 500. The bombers were two former U.S. Army soldiers, Timothy McVeigh and Terry Nichols, who shared a hatred of the federal government.

Chris Fields, a firefighter who responded that day, said when he and his crew first arrived, he felt like they were all standing in shock, looking at the destruction of the nine-story building.

“If you would have told me right then, when I first saw the building, that there were only 168 fatalities, I would have thought that there was just no way, looking at the damage,” Fields said.

Fields was captured in a Pulitzer Prize-winning photograph from that day, holding the body of 1-year-old Baylee Almon, which became a national symbol of the bombing.

Fields said he struggled with feeling like he was singled out from the department in the photo but received support from colleagues who said it represents all first responders and the innocence lost that day.

“To look at it that way and take myself out of it, it’s really helped,” Fields said.

Since the bombing, Fields said Oklahoma City has risen “like a phoenix.”
