‘I was scared', Perth mum who stabbed daughter's secret boyfriend tells jury
Jennifer Mui Len Chin, 49, has pleaded not guilty to causing bodily harm after the boy was left with four superficial stab wounds.
Chin was arrested and charged after the incident on October 17, 2023, and admitted using a 23-centimetre kitchen knife to stab the boy on each side of his chest and twice in his shoulder.
However, she has stood by assertions she believed he was an intruder who had broken into the family's Parkwood home.
Malaysian-born Chin, who is a conservative Christian, told the court she and her husband had a rule that her daughter, who was also 14 at the time, could not date or have male friends in the house.
During Chin's trial, which began on Tuesday, the mother told the court she was concerned about her daughter's sexualised behaviour, which had previously led to her iPad being confiscated.
But under cross-examination, prosecutor Chadd Graham put it to the mother-of-two that she realised her daughter had snuck a boy into the house after she found him in her husband's bed half naked, and, 'acting out of anger', she asked her son to pass her a knife before stabbing the teenager.
'I suggest you did it because you were angry,' Graham asked.
'No,' Chin replied.

‘Same issues since 2005': People wrongly detained due to Home Affairs' systemic failures
A culture of 'act first, check later' in the Department of Home Affairs led to repeat mistakes causing almost every wrongful detention in a single year, including an Australian citizen and a person who was held for a year and a half before being released. The Commonwealth Ombudsman revealed in a report on Wednesday that the department wrongfully detained 11 people between July 1, 2023 and June 30, 2024, with officers failing to decide for themselves whether it was reasonable to detain someone in most of the cases. The report said 90 per cent of the cases would have been avoided if existing policies had been followed, and that the same mistakes – including poor record keeping and failure to check conflicting information – had been made before but were not fixed. One person was detained for a week despite receiving an invalid visa refusal letter – the same mistake that had resulted in a man being incorrectly detained in 2018 for four years. 'Since we began monitoring the issue in 2005, we have observed the same types of errors are causing people to be wrongfully detained,' the report said. 'In addition, the department has not improved the way it addresses its mistakes with the individuals it has wrongfully detained. The department does not offer people it has wrongfully detained any form of redress, formal apology, or financial compensation.' Immigration detention staff can lawfully detain a person if they 'know or reasonably suspect' them to be an unlawful non-citizen. Wrongful detentions occur when the suspicion is incorrect and the person is released, according to the ombudsman. It did not analyse whether Home Affairs officers reasonably held suspicions about detained people in the first place, saying that would be too legally complex. The report said the data indicated that a culture of carelessness first identified in 2007 may still be present. In 81 per cent of the cases, staff acted as if the decision to detain a person had already been made by someone else and did not take responsibility for forming reasonable suspicion in their own minds. The ombudsman regularly reviews wrongful detention in part as a response to the case of Vivian Alvarez, a Filipino-born Australian citizen who was deported in 2001 after being admitted to hospital after falling into a drain. Her former husband searched for her for years, and she featured on missing persons television program Without a Trace. The department was made aware of its mistake by multiple sources in 2003, but took no action. Alvarez's case didn't become public until 2005.

Hope new images will crack cold case 50 years on
It is hoped new images of a man wanted for the brutal rape of his neighbour 50 years ago will finally bring him to justice. The 30-year-old woman was asleep in her Melbourne home in the early hours of July 22 1974, when she was woken by a stranger and raped. Nine days later police charged her neighbour George Karakis with rape, burglary and indecent assault. He was bailed on a $1000 surety put up by his wife and has been on the run ever since. He would now be 78. NSW Police thought they had found him in Sydney's eastern suburbs in 1990, but he disappeared again before a warrant could be executed. A public appeal in 2015 also failed to locate the Greek speaking, Turkish-born fugitive. More than 50 years after his arrest, police on Monday released his 1974 mug shot as well as a digitally generated image of what Karakis could look like today. At the time of the attack, Karakis was 27 and livingwith his wife, sister and brother-in-law in Gore Street, Fitzroy - the same street the rape occurred. Detective Senior Constable Ruby Roberts said Karakis' victim was now in her 80s and had been forced to live most of her life knowing this man had not faced court for the "brutal" crime. "The victim has spent the last 50 years with this hanging over her head," Det Roberts told reporters on Monday. "She deserves to feel safe in her home, she deserves to known that the man who assaulted her has been brought before the courts. "She's obviously still affected by what occurred and it would mean the world to her to know that he has been located." Given the length of time since his arrest, police say there is a possibility that Karakis has died but are hell bent on finding answers so they can close a chapter in the victim's life. Det Roberts also called on anyone who worked with Karakis at the Ford Factory in Broadmeadows, where he was arrested, to come forward with any information they may have. Anyone with information about Karakis's whereabouts is urged to contact Crime Stoppers on 1800 333 000 or make a confidential report at It is hoped new images of a man wanted for the brutal rape of his neighbour 50 years ago will finally bring him to justice.
