A Chinese man’s brutal killing of his girlfriend before he fell from a Sydney unit block left the woman’s devastated family in immeasurable grief and pain, a court has heard.
Weijie He stabbed 19-year-old student Liqun Pan in the southern Sydney suburb of Wolli Creek on June 27, 2020, before he fell from the fourth floor of the apartment building.
An emotional statement from Pan’s father was read out in the NSW Supreme Court, as her 24-year-old killer listened on wearing prison greens and seated in a wheelchair.
”Our hope and happiness evaporated the moment her life was viciously taken away,” Zewu Pan said in the statement, which was written in Mandarin but read to the court in English.
Her family supported her desire to get a better education, the court heard.
However, the kind, intelligent and conscientious woman’s life was cut short with her brutal murder.
”Why is God so unfair to her?” her father said.”Why is God so cruel to us?”
Pan said he hoped to see the “vicious and heartless murderer” rot in jail for the rest of his life.
”He must be made to pay for his evil deed.”
The court heard He was a regular user of nitrous oxide, commonly known as laughing gas, consuming five boxes two days before the murder.
Defence barrister Geoff Harrison argued his client had experienced drug-induced psychosis at the time of the killing.
But forensic psychiatrist Adam Martin told the court the Chinese national had shown “a degree of control and coercive behaviour” towards Pan before the murder.
He argued with his girlfriend, believing she had a 50-year-old “sugar daddy” five years earlier, and threatened to beat her up if she did not complete her chores, according to agreed facts filed with the court.
Flying back to China in March 2019, Pan signed a contract that she would not go to bars, drink alcohol, do anything with people of the opposite sex or put her phone on silent.
The contract claimed that violating its rules showed the “disappearance of love” and that He did not matter to Pan.
Forensic psychiatrist Dr Richard First said drug-induced psychosis was the “most likely” motive for the murder.
However, he accepted there were other alternatives.
”There is a non-psychotic possibility here - that this was just a straight-out domestic violence murder?” asked Crown prosecutor Rossi Kotsis.
”There is that possibility,” First said.
Justice Julia Lonergan will have to consider whether He’s moral culpability was reduced because of the claimed psychotic episode or if he was intoxicated by the laughing gas.
