BUFFALO, N.Y. -- A 19-year-old who tried to shoot a Buffalo Police officer pleaded guilty Monday to attempted murder among other charges, according to the Erie County District Attorney's Office.

On June 15th at about 11:30 p.m., Buffalo Police Officer Anthony Fanara saw Fuller fleeing from the scene of a robbery at Doat Street and Stewart Ave. in Buffalo.

The officer chased down the suspect and was joined by two other officers.

Fanara caught Fuller and tired to grab his loaded .45 caliber handgun.

This is when Fuller pressed the gun into the officer's chest and pulled the trigger twice. But the gun did not fire.

Another officer then knocked the gun from Fuller's grasp and Fuller was handcuffed.

Fuller pleaded guilty to the charges of second-degree attempted murder and second-degree criminal possession of a weapon. He faces 15-20 years in prison and will be sentenced Jan. 4 at 9:30 a.m. He has been sent to jail without bail.
