Thanks for the link.I am not sure this is the same story... I remember reading it a few days ago, but was under the impression it had happened very recently, this story is from last May. But the description of a security guard firing and accidentally hitting a student is VERY similar.
I haven't found a more recent article yet.

One paragraph from the article.
Investigators are also looking into the possibility that a bullet fired by that security guard may have hit and wounded one of the students who was injured in the attack. That question is not likely to be settled until all ballistics testing is completed.
It also stated that the security officer was a former Marine and sheriffs deputy.
