Officers were dispatched to a robbery in progress and upon arrival at the location observed a suspect matching the description of the robbery suspect. The suspect was observed to have a weapon, thought to be a knife, in each hand (later identifed as a screwdriver and scissors). The suspect refused to obey commands to drop his weapons and to lie on the ground. A Conductive Electronic Device was deployed but did not affect the suspect. The suspect charged toward an officer with weapons in hand and the officer, in fear of his life, discharged his weapon, killing the suspect.
