A tragic incident has unfolded in Mosman Park, Western Australia, with the discovery of a family of four – a 50-year-old man, his 49-year-old partner, and their two teenage sons, aged 14 and 16 – found deceased in what authorities are treating as a double murder-suicide. The devastating scene unfolded on January 30, 2026, after a care professional arrived for a scheduled appointment and, receiving no response, alerted police.
Discovery and Initial Response
The incident began shortly after 8:00 AM local time when a care professional contacted authorities after being unable to reach the family at their home on Mott Close. Upon arrival, officers discovered the bodies of the two parents, their two sons, along with their two dogs and one cat. Detective Inspector Jessica Securo, of the Major Crime Division, confirmed the initial assessment. “At this stage, there’s two parents and two children, so we woudl treat it as a double murder-suicide,” she stated.
five ambulance crews were dispatched to the scene and remained for approximately two hours while the coroner conducted a preliminary assessment. Police established a perimeter, advising the public to avoid the area while the examination commenced.
Investigation underway
Authorities are currently working to establish a precise timeline of events leading up to the tragedy. According to Detective Inspector Securo, a note was discovered at the scene, providing the strongest indication that the deaths were the result of a murder-suicide, though its contents have not been disclosed. “It will take time for police to investigate the full circumstances surrounding this incident,” she added.
Notably, investigators have confirmed that a weapon was not used in the deaths and that the incident did not appear to be overtly violent. WA Police are attempting to determine when the family was last seen alive.
Family Background and Community Impact
Details emerging suggest the family had strong ties to one of Perth’s elite private schools,and both teenage boys experienced developmental disabilities. This information, while sensitive, provides context to the profound loss experienced by the community.
The tragedy has deeply impacted local residents. darryn Boult, a neighbor, described the scene as one of significant police activity. “There was probably about five police cars there so there was quite a bit of action that’s happened,” he told 9News Perth. Another resident, Geoff Stewart, recounted hearing sirens and witnessing a rapid police response. “I heard the police siren coming up behind me…within about 10 minutes there was [multiple] police cars marked and unmarked.”
Federal Curtin MP Kate Chaney, representing the Mosman Park electorate, expressed her shock and devastation. “My thoughts go out to the friends and relatives of this family, as well as the first responders, and the neighbours and local community who knew them,” Chaney stated. “This heartbreaking loss of four lives will have lasting effects throughout our community.”

Multiple police crews and officers remain at the scene as of Friday afternoon, continuing their investigation. The Town of Mosman Park has closed several roads in the vicinity and directed inquiries to the police.
