It appears to be the same guy.
Here is an article with some insight on the situation:

One retired officer that I talked to said that the "gun on campus" has become the new "bomb threat". Bomb threats became so ubiquitous in the 70's that severe penalties were put in place and enforced, for people calling in fraudulent bomb threats. The cost of institutions being forced to shut down for hours at a time is enormous.
But "Gun!" threats are politically correct.
Can we still yell "FIRE!" in a crowded theater?
