Police radio transmissions from the Fort Hood shooting Wednesday lay bare the chaos in the wake of gunfire.
"We have an active shooter currently on Fort Hood," a female voice can be heard saying in the recording. She adds that one of the gunshot victims was "walking around conscious and breathing."
Later, a female voice can be heard saying that some people on the base were "escaping through windows." She adds that the shooter is a "specialist in the unit."
The gunman, identified as Ivan Lopez, 34 — an enlisted soldier — took his own life, officials said.
Four people were confirmed dead late Wednesday, including the gunman, and 16 others were wounded in the shooting, military officials told NBC News.
