Frankum ran into the rooftop car park and held a car owner at gunpoint, demanding that she take him to Enfield, a nearby suburb. Before the woman could start her car, police began to arrive on the scene with Constable Darren Stewart the first to arrive. He was shot at in his police car by Frankum from the car park rooftop, Stewart had run through the Strathfield shopping centre to engage Frankum, but, upon arriving at the carpark rooftop, Frankum shot numerous rounds into the door leading to the carpark, pinning down Stewart. Upon hearing more approaching sirens, Frankum apologised to the woman and then got out of the car, knelt on the ground, and committed suicide by shooting himself in the head.
