We have no information on who did it or why, and (we) are investigating.

He's the one who called it in so we were on the scene right away.

That is a possibility, it's one of the things we're looking at.

There might have been an accidental discharge or it could have been a hit-type of incident.

We don't have any physical description. We don't know how many subjects were involved, which is mind-boggling, with all those people around.

We are interviewing all the witnesses we can to hopefully develop a composite.
