"Another school employee alerted police to the message, which was left on an answering machine. The call prompted police to make a “welfare check” Saturday at the home of Robert Csak"

So, we are never told what this message was only that it was "threatening". But apparently not "threatening" enough to get a warrant. So they pull the old "welfare check" trick and the cop just happens to see the weapons in plain sight. This was a set up.

Exactly.
