IT'S A POLICE STANDOFF ACROSS THE STREET FROM THE CAMPUS. YOU SEE THE MAN STANDING THERE WITH A SHOTGUN. AS OFFICERS ARRIVED AND SET UP POSITION, THE SHOTGUN WAS POINTED IN THEIR POSITION. Chauncy: THEY TRIED TO GET HIM TO PUT HIS WEAPON DOWN AND AT ONE POINT, HE POINTS IT AT HIMSELF. THE OFFICERS TOOK COVER AND WERE ABLE TO NEGOTIATE AND TALK TO THE SUSPECT DOWN.

INVESTIGATORS TELL ME IT ENDED PEACEFULLY AND THEY ALSO SAID THE SUSPECT DID NOT FIGHT OR RESIST ARREST AND EVERYTHING WAS OKAY IN A MATTER OF A FEW
