Chris Mintz "tried to protect some people," his aunt Sheila Brown told NBC News in a telephone interview. "We were told he did heroic things to protect some people."
She said that Mintz was shot seven times and had been in surgery since the shooting that left 10 dead, including the gunman.
Originally from Randleman, North Carolina, Mintz served about 10 years in the Army. He had just started college, Brown said. He was shot in the back, abdomen and hands, and had two broken legs, she added.
"We're not sure how his legs got broken," she said. "He was on the wrestling team and and he's done cage-fighting so it does not surprise me that he would act heroically."
