A Rockingham man has pleaded guilty over an incident that left his 13-year-old stepson with a gash in his head that needed seven stitches. Ryan Dumencic, 43, appeared before Rockingham Magistrates Court on Wednesday, where he was charged with unlawfully wounding his young stepson. Prosecutor Senior Constable Jessica Anderson told the court that Dumencic and the victim were involved in an incident at the family home sometime between August and May. After instructing the 13-year-old to do his homework, Dumencic became frustrated as his stepson was not following instructions. Dumencic took a small ceramic bowl and hit it over the victim’s head, which caused a laceration along the hairline. The 13-year-old was taken to hospital where he was treated for the cut with seven stitches to the head. Hospital staff reported the incident to police. Sen. Const. Anderson said Dumencic made full admissions to police and was extremely remorseful for his actions, agreeing that his parenting techniques were not acceptable. Dumencic was placed on the Connect and Respect behaviour program prior to sentencing. Dumencic’s lawyer was not present, but agreed to Magistrate Vivian Edwards proceeding with sentencing. “I have apologised to my stepson and entered into the Connect and Respect program,” he said. “I’ve had time to think about my parenting techniques and it won’t happen again. He pleaded guilty to unlawful assault and was ordered to complete a nine-month supervision program with requirements and pay $259.30 in court costs.
