First responder describes scene of San Bernardino shooting: 'It was unspeakable'

San Bernardino Police Lt. Mike Madden, a 24-year veteran of the department, was on his way to lunch at 11 a.m. Wednesday when he got the call.

He was the first officer to arrive at the scene of the Inland Regional Center, where a shooting rampage left 14 people dead and 21 injured.

At a press conference Thursday night, Madden spoke emotionally about the scene of the massacre and the "pure panic" on the faces of the injured.

Madden said other officers arrived within two minutes, and together they made their way into the building.

"It was unspeakable, the carnage that we were seeing, the number of people who were injured and, unfortunately, already dead, and the pure panic on the faces of those individuals that were still in need and needing to be safe."

"It was extremely loud," Madden went on to say. "The fire alarms were going off. There were people who were obviously injured and obviously in great amounts of pain. And that was evident in the moans and the wails that we were hearing."

The names of the victims were released also Thursday evening, ranging in age from 26 to 60.

The husband-and-wife attackers later died in a gun battle with police after an hours-long manhunt, leaving behind thousands of unused bullets and several pipe bombs.
