Brian Mulder suffered a gunshot wound to the leg.
The shooting happened on the morning of February 19 outside of a residence hall on the NIU campus in Dekalb.
Mulder was released from the hospital Monday night. He says he is grateful to be recuperating at home and alive to tell his story.
Mulder is the hall council president for the Stevenson North dormitory. He says he came to the aid of a female student after he says she was being followed inside the dorm by an apparent unwanted suitor.
"I suggested to him that he should get out of here because he didn't have any business being at the dorm. And somehow at that point he was frustrated, even more or something, grabbed a gun out, pointed at my face and I asked him if he was going to shoot me and his eye flinched so I grabbed the gun and pulled it down. He backed away and ended up aiming towards my leg and shooting," said Mulder.
Mulder says he didn't know that he had been shot until he looked down and touched his leg. The bullet missed his bones and arteries but it did go through his leg. Mulder says he's in a lot of pain and doctors says he will walk with a limp for weeks.
Mulder says he had gone outside around 3:30 Friday morning to smoke a cigarette with a friend when he was confronted by the gunman.
Friday police said the shooting was an isolated incident between two students involved in an altercation.
Zach Issacman, 22, is charged in the shooting. He is an NIU student but Mulder says he had never seen Issacman before.
After the shooting, the school was put on lockdown and it brought back memories of the deadly shooting at Cole Hall in February of 2008.
Mulder wasn't there two years ago, but the incident still remains fresh in his mind.
"I don't know what this kid's intentions were. He had a gun, he's walking up to a dorm trying to get in. I don't know if he was trying get in to maybe shoot people or shoot one person or maybe do nothing with it," said Mulder.
"I'm proud of him because he actually did the right thing because he was concerned about somebody trying to get into the dorm late at night," said Caryn Mulder.
Mulder says he has been given permission to go back to class on Thursday.
As for Issacman, he has been suspended from the university and is scheduled to appear in court on Tuesday. He faces felony weapon and battery charges.
