Stop in for a cup of coffee

Saw that, could be an employee, gone postal, no pun intended. No details that I can find.

take this for what its worth, 3rd hand information.
I just got off the phone with her dad. He’s talked to one of his buddies already up there. Some guy entered with a rifle yelling stuff in what sounded like a foreign lanaguge but his buddy couldn’t be sure, i guess it’s quite loud in there and they all wear ear protection. This happened right at shift change I guess.
