Aftermath

A similar murder-suicide was mentioned as occurring in Australia: Ronald Jonker, 32, gassed himself and his three children David, 7, Aaron, 5, and Ashlee, 17 months, on the northern outskirts of Perth. Another incident was also mentioned in the provided material: Mark Heath drove his four young children, Sarah 8, Holly 6, Jak 4 and Kaleb 2, to an isolated bush track around 250 kilometres south of Perth, Western Australia, and connected a hose to the car’s exhaust; on Saturday July 24, all five bodies were found in the car dead from acute carbon monoxide poisoning.

The provided material also included discussion of media coverage and other commentary, including quotations and references to counselling services, suicide statistics, and statements by named individuals:

  • A police spokesman declared: “Life is never that black that you have to take your own children's lives.”
  • Jim Leaman, who lived near Heath's former wife and children, commented: “You have to feel sorry for him. I know a lot of people would hate a bloke like this, but he has got a story to tell as well.”
  • Forensic psychologist Tim Watson-Munro warned: “You are looking at a crisis situation,” and said: “Obviously something is failing in the system in terms of detection and, in a broader sense, in terms of prevention.”
  • Allan Huggins, director of Men’s Health, Teaching and Research at Curtin University in WA commented: “I think it [Heath's response] very much reflects the lack of services available for people in crisis, particularly men.”
  • The provided material quoted Leon Trotsky: “The point was not to laugh or cry, but to understand.”
