McKinley, as he testified at an October preliminary hearing, told agents that he saw Bruce at Richardson’s Monday bar, and as McKinley ran to aid, he saw Richardson holding a semi-automatic handgun. . McKinley also said that Richardson pointed a gun at him, and saw him pull back the slide to shoot the gun into the chamber.
McKinley said he held the gun with both his hands. He said Richardson had a gun in his left hand and that his finger was on the trigger guard. As McKinley tried to push the gun down with his hands, he heard a gunshot, saw a muzzle flash and felt the gun recoil in his hands.
McKinley told agents that Richardson tried to chamber another round but was able to stop him from doing so until the other officers disarmed Richardson.
