A man has been found guilty of murdering a schoolgirl at her family’s Chinese takeaway. Wenjing Lin – also known as Wenjing Xu - was strangled at the takeaway in Ynyswen, Rhondda Cynon Taf, on 5 March. A jury at Merthyr Tydfil crown court convicted Chun Xu of the 16-year-old’s murder. The 32-year-old was also found guilty of attempting to murder her stepfather, Yongquan Jiang. Wenjing lived at the takeaway in Baglan Street with her mother, Meifang Xu, and Jiang. The trial heard how Chun Xu was a heavy gambler and owed the family £14,000. Michael Jones QC, prosecuting, told the court Xu had visited the family armed with a kitchen knife, and an hour before the attacks had Googled “can fingerprints be destroyed by fire”. When he was later questioned by a psychologist about his fitness to be questioned by police, he said: “I didn’t mean to hurt the little girl. I wanted revenge on her mother. She upset me on many times and didn’t listen to what I say.” Chun Xu, also known as Little Gang, was regarded as a nephew to Wenjing’s mother as their parents had lived next door to each other in China, but they were not blood relations, Jones said. In December 2020, the family entrusted Chun Xu with £20,000 that he said he would send back to China for them to pay a friend who had lent them money to start their business in the UK. However, he only sent some of the money back and gambled away £14,000, which he had then begun paying back. On 4 March, 2021, he rang Meifang Xu and asked if he could come to see them, but told her not to tell anyone about his visit. That night they ate food together and everyone went to bed. The next morning, Jones said, he “strangled to death 16-year-old Wenjing”. An hour before the attack he is said to have Googled different variations of whether “finger prints on knife will still exist if burnt by fire”. After killing Wenjing, Chun Xu is said to have lured Jiang into the basement by asking whether he could have a piece of fish from the freezer. In the basement, Chun Xu began attacking Jiang with two knives, stabbing him in the neck and body. When Jiang asked why Chun Xu was attacking him, he replied: “Money, money, money.” Meifang Xu then came down the basement stairs and saw the two fighting. She tried to ring a friend, and Chun Xu bit her. Jiang fought Chun Xu off and went upstairs to find his stepdaughter, Wenjing. He discovered her lying on her back by the takeaway counter. Despite attempts by the family and then paramedics to resuscitate the teenager, she was pronounced dead at the scene at 12.59pm. Police found Chun Xu in the kitchen, having cut his own throat. He was treated at University hospital of Wales before being arrested on suspicion of murder and attempted murder. A statement from Wenjing’s teacher Rhiannon Davies was read to the court during the trial. Davies, who oversaw Wenjing’s year 11 at Treorchy comprehensive school, described her as an “exceptional” and “hardworking” student. “Even on the day of her death I was made aware she had logged in for a maths lesson early in the morning,” Davies said. “She was a fantastic student and is sorely missed.” Chun Xu admitted attacking 38-year-old Jiang, but denied intending to kill him or cause him serious harm. He had pleaded guilty to Wenjing’s manslaughter. He will be sentenced on Friday at the same court.
