Officer worker Tony Gioia told the inquest he tackled Vitkovic, having just witnessed a co-worker being shot dead at point-blank range. Gioia believed he would be the next victim once Vitkovic turned around and saw him. Gioia said during the scuffle, Vitkovic lunged for the window and struggled to get out, until he was hanging from the ledge with Gioia holding Vitkovic by the ankles. Despite others helping to restrain Vitkovic, he struggled free and fell to the street. A woman in an adjacent office building told the inquest she believed she saw a man in a blue jumper throw the man onto the balcony, and then push him out when he moved back to the window. Under cross examination, she incorrectly identified this as occurring on the building's 10th floor, not the 11th, and stated that her building was from the Australia Post building.
