They found that Dr Boros-Lavack had missed opportunities to put him back on anti-psychotic medication, one member of the panel saying she had "not taken seriously enough" the concerns from Cauchi's mother in late-2019.The panel also gave evidence at the inquest that Cauchi was "floridly psychotic" - in the active part of a psychotic episode – when he walked into the shopping centre.

When questioned by the lawyer assisting the coroner, Dr Boros-Lavack stressed: "I did not fail in my care of Joel."She had earlier told the inquest she believed Cauchi was not psychotic during the attack and that medication would not have prevented the tragedy.Dr Boros-Lavack said the attacks may have been "due to his sexual frustration, pornography and hatred towards women".

But the next day, she withdrew that evidence, saying it was simply "conjecture" and she was not in a position to assess Cauchi's mental state, having not treated him since 2019.However the inquest is investigating whether Cauchi targeted specific individuals or groups.

For Peter Young, the brother of Jade, the answer seemed clear. "Fuelled by his frustration with not finding a 'nice' girl to marry", his "rapid hunt found 16 victims, 14 of which were women," he told the inquest.

The NSW Police Commissioner in the days after the attack said it was "obvious" to detectives that the offender had focussed on women.He later realised that "there really weren't any colleagues with overseas undergraduate background in the department".

He went back to the US and did his master's at Johns Hopkins University, and now works at Chinese tech giant Baidu.But despite the degree from a prestigious American university, Mr Chen does not feel he has an edge because of the stiff competition from graduates in China.

What also has not helped is the suspicion around foreign graduates. Beijing has ramped up warnings of foreign spies, telling civilians to be on the lookout for suspicious figures.In April, prominent Chinese businesswoman Dong Mingzhu told shareholders in a closed-door meeting that her company, home appliance maker Gree Electric, will "never" recruit Chinese people educated overseas "because among them are spies".
