Utica, NY (WIBX) - Following a lengthy investigation, Utica Police say no charges will be filed in the stabbing death of 20-year old Pee Ha of Utica.

Ha was killed last November on the 1300 block of Brinckerhoff Avenue.

Police say the investigation revealed that Ha, who was in possession of a mop handle broken down to be a weapon, attempted to rob 17 and 13-year old brothers who were walking along the street.

A fight ensued and the 17-year old stabbed Ha in the chest with a pocket knife one time in an attempt to protect himself and his younger brother.

Both Utica Police and the Oneida County District Attorney's agree that based on the facts and evidence, they can not overcome a claim of self defense.
