An HPD officer was assisting in an investigation, regarding a vehicle that was stolen during an Aggravated-Robbery. The officer approached the driver of the vehicle at which point the driver sped towards the direction of the officer. The officer, in fear of his life, fired his duty weapon once at the suspect, striking the front windshield. The suspect fled the location in the vehicle but crashed, striking a tree at a near-by residence. The suspect fled on foot but was arrested and charged for unauthorized use of a motor vehicle.
