the officer in charge. Con Margelis testified to the coronial enquiry that he and Vitkovic had been friends for several years. Margelis said after Vitkovic arrived to see him on 8 December, he pulled out his rifle, tried to pull the trigger and then aimed it at a female colleague and told her not to move. Knowing that Vitkovic could not move quickly due to a bad knee, Margelis jumped over the counter and hid in the women's toilets on the 5th floor. Margelis said he expected that Vitkovic would come after him, leaving others in the office safe. Of possible reasons for Vitkovic's actions, Margelis said he had not seen Vitkovic in the months prior, adding that "I can't really explain". Margelis said Vitkovic had become depressed and embittered after injuring his leg playing tennis, followed by a failed operation to repair the damage. Margelis said he began to see little of Vitkovic due to his depression.

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. The counsel assisting the coroner, Julian Leckie, judged that this witness was "honest but mistaken". He said that photographs showed Gioia was not wearing a blue sweater on the day. Evidence showed that Vitkovic tried to jump
