"It felt like you were at war," Dr. Comilla Sasson, one of two attending physicians working the overnight shift at University of Colorado Hospital, told The Denver Post. "The sheer number of people you're seeing, and the extent of their injuries, is so unnatural."
Victims with multiple gunshot wounds arrived to six area hospitals via ambulance, police cruisers and private vehicles shortly after suspect James Holmes opened fire at the midnight screening of "The Dark Knight Rises" at the Century Aurora 16 theaters, the Post reported.
"And it's not just one or two people with that injury," recalled Sasson. "They just keep coming in the door, and we don't know when they're going to stop."
Dr. Frank Lansville, medical director of emergency services at the Medical Center of Aurora, said the high-caliber weapons Holmes allegedly used caused "massive tissue destruction."
