'A Real Angry Kid,' Wounded Teacher Talks to 'Nightline'

— -- Below is a transcript of an interview with David Kachadourian, one of the teachers shot Wednesday by student Asa H. Coon at SuccessTech Academy in Cleveland. Four people were shot before Coon killed himself.

Kachadourian was interviewed on ABC's "Nightline" by correspondent Martin Bashir.

BASHIR: And I'm joined by David Kachadourian, one of the teachers at the school who was shot by the gunman.Mr. Kachadourian, good evening, at the end of probably the most traumatic day of your life.

KACHADOURIAN: Good evening.

BASHIR: How are you feeling?

KACHADOURIAN: I'm feeling OK. I'm feeling physically fine.

BASHIR: Can you describe what happened today at the school?

KACHADOURIAN: Well, it started off as a pretty average day. It was dark and cloudy. I rode my bike into school and had my first two classes uneventfully. They were pretty good. It was a pretty good day. And it was raining outside.

And then my third class was after lunch and it was at the end of this class, almost to the end of the class, there was this loud popping noise and I wasn't sure what it was.

I didn't think a whole lot about it, but then there were people sort of running and yelling in the halls. And at that point, the kids in my room started yelling and they started running down the stairs.

A moment or two after that, a student appeared in the hallway with two guns in his hands and waving them around and something. I couldn't exactly tell what he was yelling.

BASHIR: As he came in, did you recognize him immediately as one of your students? Because you're a math teacher at the school.

KACHADOURIAN: Yes. Yes, I did, immediately.

BASHIR: So you knew the student.

KACHADOURIAN: I'm sorry?

BASHIR: You knew this young man.

KACHADOURIAN: Yes, yeah.

BASHIR: So what happened then?

KACHADOURIAN: I had him [in my] class. And then he was waving the guns around and I wasn't entirely convinced they were real. I thought they might be starter pistols or something like that.

But as the kids were going down the stairs, I went to the doorway to the stairwell and, at that point, there was another pop and I felt something in my back that felt like I would imagine a paintball to feel. It's sort of a heavy hit, pressure, but not like what you would expect a gun.
