Woman was found in a pool of blood on her bedroom floor, with 18 head wounds A son hacked his mother to death after she told him he should take a shower, a Court of First Instance jury heard yesterday. Hung Yuen-man, 32, has pleaded not guilty to the murder of Chau Sau-biu on April 4 last year. Chau, 58, was found by her younger son lying in a pool of blood on the floor of her bedroom. She had suffered 18 chop wounds to the head. Prosecutor Dee Crebbin told the court that Chau rang her sister-in-law, Kwok Sau-king, for a chat at 8pm. Ten minutes after the call had ended, Ms Kwok again heard the phone ring but when she answered it she could only hear a female voice groaning in pain. Ms Crebbin said Ms Kwok thought it was a prank call and hung up, only to find it rang again. When there was no sound from the other end, Ms Kwok's husband looked at the caller display and found it was from Chau's home, she said. Ms Crebbin said the couple called Chau's younger son, Hung Yuen-yuen, and they all went over to Chau's home in Yu Yan Street, Kwun Tong, to investigate. After pushing open the wooden door and peering through the locked iron grill, Mr Hung saw bloodstains inside the house and the phone handset dangling from the wall socket. Ms Crebbin told the court that when they called out, the defendant kicked the grill and told them to go away, saying his mother had gone out. Mr Hung then crawled through a toilet window and found his mother lying on her bedroom floor in a pool of blood. Ms Crebbin said emergency services were called but Chau was declared dead upon arrival at the United Christian Hospital. During a subsequent police interview, Ms Crebbin said the defendant told investigators he had attacked his mother several times with a chopper after she told him to take off his dirty clothes and have a shower. A post-mortem examination found Chau had suffered 18 chop wounds to the head, a fractured skull, multiple cut wounds and bruising. The cause of death was a chop wound to the head, Ms Crebbin said. The trial, before Madame Justice Clare-Marie Beeson, continues today.
