FORT HOOD, Texas -- The U.S. Army allowed news reporters on the grounds of Fort Hood on Friday for the first time since the rampage that left 13 people dead and 30 wounded.

KSAT 12 News reporter Tim Gerber was among the first reporters who were allowed to interview some of the medical personnel and first responders who treated the victims.

Sgt. Andrew Hagerman, a military police officer at Fort Hood, arrived at the scene of the attack moments after civilian police Officer Kimberly Munley exchanged gunfire with the shooting suspect, Maj. Nidal Malik Hasan.

"I moved toward the scene after hearing shots fired," Hagerman said. "You kind of don't know what's going to happen at that moment, and then definitely, when the call came over that an officer was down, we all converged on scene."

Hagerman said there were multiple victims on the ground and Hasan was quickly handcuffed after weapons were discovered next to his unconscious body.

At that point, several soldiers who flooded the scene began ripping their clothes off and used them to dress the wounds of the victims.

Lt. Col. Larry Masullo, chief of the emergency department at the post hospital, said that initial treatment kept the death toll to a minimum.

"What those medics and soldiers did out there ... (They) probably saved multiple lives," Masullo said. "They control the bleeding until they can get to the definitive care in the ER. And then we can fix what needs to be fixed. So, just a tremendous effort at the scene."

Medical personnel said that constant training and combat experience played a crucial role in saving lives and that everyone knew what their job was and they all performed as expected.
