A tragic and deeply disturbing incident unfolded in the affluent Perth suburb of Mosman Park on Friday, January 30, 2026, when the bodies of a family of four—parents Jarrod Clune, 50, and Maiwenna Goasdowe, 49, along with their two teenage sons Leon Clune, 16, and Otis Clune, 14—were discovered inside their home on Mott Close, together with three family pets: two dogs and a cat.

Western Australia Police responded to the scene around 8:15 a.m. after a support worker, who provided care services for the boys, arrived at the property and found a note instructing not to enter and to call authorities immediately. Upon entry, officers located all four family members and the pets deceased in what has been classified as a suspected double murder-suicide. Homicide detectives are leading the investigation, treating the deaths of the teenagers as murders allegedly committed by one or both parents before they took their own lives.

Detective Acting Inspector Jessica Securo described the discovery as a “devastating tragedy” during a media briefing shortly after the scene was secured. She confirmed the identities and ages of the deceased and noted that both boys had experienced “significant health challenges.” Reports from multiple Australian outlets, including news.com.au and 7NEWS, indicate the teenagers were on the autism spectrum and received ongoing support services. The exact nature of their conditions has not been publicly detailed beyond this, but the family had engaged with care providers, one of whom became the key witness who raised the alarm.

A note was found at the property, though its precise contents have not been officially released. Subsequent reporting from WA Today, the Sunday Times, and other sources revealed the discovery of a second note inside the home. This additional letter reportedly suggests the parents had planned the event together and made a joint decision to end their lives and those of their children. Police have described the notes as containing instructions or warnings, but have withheld full details pending further investigation and to respect the family’s privacy during what remains an active inquiry.

The cause of death for the family and pets has not yet been publicly confirmed, with forensic examinations and autopsies ongoing. No weapons or other specific details about the method have been disclosed, and authorities have emphasized that the scene showed no signs of forced entry or external involvement. The pets’ deaths appear linked to the same event, though specifics remain unclear.

Mosman Park, a wealthy riverfront suburb in Perth’s west, is known for its upscale homes and quiet, family-oriented streets. The Mott Close residence is a double-storey property in one of the area’s most desirable pockets. Neighbors and the broader community expressed profound shock in the hours and days following the discovery. Local media captured images of police cordons, forensic teams in white suits, and a steady presence of investigators as the home was meticulously examined.

The boys attended school in the area, and records shared in media reports paint a picture of two young individuals who faced daily challenges but were part of a supportive family environment. Friends, educators, and care workers have spoken of the family’s dedication to the boys’ well-being. The tragedy has prompted an outpouring of grief from the local community, with tributes focusing on the unimaginable burden the parents may have carried and the profound loss of four lives.

Western Australia Premier Roger Cook described the incident as an “unimaginable tragedy” and urged compassion for all affected. Counseling services have been made available for family, friends, school communities, and first responders who attended the scene.

As the investigation continues, police have appealed for anyone with information to come forward, though they stress there is no current indication of third-party involvement. The case has reignited discussions in Australia about mental health support for families caring for children with significant disabilities, the pressures of long-term caregiving, and access to crisis intervention.

This heartbreaking event serves as a somber reminder of the hidden struggles that can exist behind closed doors, even in seemingly idyllic settings. The loss of Jarrod, Maiwenna, Leon, and Otis—along with their beloved pets—has left a community mourning and searching for understanding in the wake of such profound sorrow.
