Western Australian police have discovered a note at a home in the affluent Perth suburb of Mosman Park where four family members, including two teenage boys with significant health challenges, were found dead in a suspected murder-suicide.
Emergency services were called to the property on Mott Close at 8:15am on Friday after a person known to the family arrived for an appointment and raised the alarm. Officers found the bodies of a man aged 50, a woman aged 49, and two boys aged 14 and 16, along with a cat and two dogs. Homicide detective Jessica Securo confirmed the deaths are being treated as a murder-suicide, with a note left at the scene. 'Yes, there was a note left at the premises although I'm not about to go into the content of that letter, it will form part of our investigation,' she said.
Securo said the incident did not appear violent and no weapon was used. The family had no reported history of domestic violence with police. Both children had 'significant health challenges' and had been in contact with care services, though Securo declined to provide further details for privacy reasons. A neighbour, who did not wish to be named, described the boys as non-verbal and said he would often see support services visiting the home. One of the boys attended Christ Church Grammar School's Peter Moyes Centre, which caters for children with autism and learning difficulties.
Police are working to establish the timeline of events, as it is unclear when the family were last seen alive. 'Did this incident happen this morning? Did it happen last night? How long have those persons been in that house?' Securo said. The bodies were found in different locations within the property. A large forensic tent was set up in the driveway, and the cul-de-sac was cordoned off as residents gathered nearby.
Local resident Henry Oroworaran described the community as close-knit, noting an annual Christmas block party on the street, though the family did not attend. Christ Church Grammar principal Alan Jones emailed families expressing condolences, stating the school would not release further statements out of respect for the family and the police investigation.
