On July 10, 1999, Williams said, he was working off duty at Caribbean Tropics. Shortly after midnight, Michael Grimm walked in with a woman of Caribbean descent. The womans estranged husband, who is also of Caribbean descent, was at the club and confronted Grimm. The two men began to argue. Williams escorted Grimm away. Williams recalled, He said to me, Thanks a lot man, he dont know who hes fucking with. Then he said something frightening. Ill fuckin make him disappear where nobody will find him. (Grimm calls this allegation insane.) After that, Williams said, Grimm and the woman left, as did the husband.
Around 2:30 a.m., there was a commotion on the dance floor. According to Williams, somebody was shouting, Hes got a gun! Following a crowd into the clubs garage, Williams discovered that Grimm and the husband had returned, and Grimm was holding a weapon. Grimm was carrying on like a madman, Williams said. Hes screaming, Im gonna fuckin kill him. So I said to him, Who are you? He put the gun back in his waist and said, Im a fucking F.B.I. agent, aint nobody gonna threaten me. (Grimm said he only moved his gun from an ankle holster to his waistband.) The bouncer at the front door told Williams that, when he patted Grimm down and found his gun, Grimm had showed his F.B.I. identification. The bouncer then let him pass through the clubs metal detector.
