A 17-year-old boy murdered an 18-year-old woman in Newman last year by bashing her with a rock before taking her body to the local hospital in a wheelie bin, a Perth court has heard. The teenager pleaded guilty to the murder charge last month and today appeared before Perth Children’s Court president Hylton Quail to be sentenced. At the sentencing hearing, which has now been adjourned until tomorrow so that the victim’s family can be present, new and tragic details of the events that lead up to the mother-of-two’s murder on May 6 were revealed for the first time. The court was told how the boy and the woman — who for cultural reasons is known as Ms Watson — had attended a house party in Newman in the evening on May 5. Police were called to the home twice that night due to disturbances and fights. Both were intoxicated and were seen arguing in the street. At one stage, witnesses saw the boy drag Ms Watson by her hair along the ground. The pair were separated, but hours later, near a dirt track down the road from the party, the young mother was struck to the head multiple times with a rock by the 17-year-old. At that point the 17-year-old threw the victim over his shoulder and carried her 1.8km to his grandmother’s house. Once there, he put Ms Watson’s body into a green wheelie bin and wheeled her to the nearby Newman Hospital. He told two nurses: “I’ve taken it too far, I hit her. I’ll leave her here with you.” The 17-year-old left the scene shortly after and withdrew $1000 cash from his bank account but he was arrested hours later. The young mother at the centre of the tragedy sustained a fractured rib and blunt force injuries to her head and face. She had no pulse and had stopped breathing by the time nurses got to her. She had just given birth to a boy and already had a one-year-old son at the time of her death. The 17-year-old’s lawyer Cillian Stockdale told the court his client was remorseful. “He told me he felt great shame,” Mr Stockdale said. “He didn’t know if he wanted to keep on living and he’s really sad. “He doesn’t remember how many times he hit her.” At the time of her death, friends and family of Ms Watson remembered her as a “good young mother” who would be dearly missed. As previously reported in The West Australian, an Indigenous elder received a tribal punishment beating on behalf of the teenage boy in the wake of the murder. Police at the time confirmed that a respected elder “attended a culturally appropriate location where he underwent his obligations according to cultural traditions”.
