A communications professor in Missouri ended up having his illegal marijuana growing operation busted after he joked about gunning down people at his university.

Northwest Missouri State University professor Matthew Rouch told a colleague on Facebook that he was always optimistic at the start of the school year. But "by October, I’ll be wanting to get up to the top of the bell tower with a high powered rifle — with a good scope, and probably a gatling gun as well," he added.

The University Policy Department learned of the comment on Wednesday and launched an investigation. Rouch was arrested and jailed the following day.

On Friday, police searched Rouch's home for weapons. They didn't find a gatling gun, but they did uncover "a significant quantity of marijuana." Police found ten live marijuana plans and various drug paraphernalia.

Rouch was charged with felony production of a controlled substance and felony possession of a controlled substance. Police, however, said they didn't have enough evidence to charge him with making a terrorist threat.

In a statement, Northwest Missouri State University said Rouch had been placed on administrative leave and banned from campus pending the outcome of a internal investigation.
