Apparently what happened was some sick individual put a post on a blog site. He/she said that they were going to take a gun to the NMU campus and "get even" with some people. The stupid thing about it was when they said they were going to go to the NMU campus, they included the address of the university.
That pretty much told me it was somebody from outside the area who has in all likelihood never even seen or been to the NMU campus. Investigators have said that this same person has posted threats aimed at other colleges that were similiarly worded. I haven't heard that the person has been caught yet, but the FBI is supposedly after their arse big time.
