Tragedy in Mosman Park: Family of Four Found Dead in Suspected Murder-Suicide

In one of Perth’s most affluent suburbs, a quiet cul-de-sac on Mott Close became the scene of an unimaginable family tragedy on Friday morning. The bodies of Jarrod Clune, 50, Maiwenna Goasdoue, 49, and their teenage sons Leon, 16, and Otis, 14, were discovered inside their home, along with the family’s three pets—two dogs and a cat.

Western Australia Police responded to the address around 8:15 a.m. after a carer, arriving for a scheduled visit, found a note on the front door urging not to enter and to call police. Officers entered the property and described the scene as a “devastating tragedy” and “highly distressing.” Initial assessments indicated no ongoing threat to the public, with no reported history of family violence at the address.

Investigators confirmed the deaths as a suspected double murder-suicide. A second handwritten note, discovered inside the home, provided critical evidence. This letter, believed to be from the parents, included the chilling plea: “PLEASE LET US REST AS A COMPLETE FAMILY…” It reportedly detailed their overwhelming despair, premeditated planning, instructions for their will and finances, and the reasons for their actions—pointing to the parents first ending the lives of their sons before taking their own.

Leon and Otis lived with severe autism and significant health challenges for many years, requiring intensive, full-time care. Both boys attended Christ Church Grammar School in Perth’s western suburbs—a prestigious institution where their father, Jarrod, had been a prefect two decades earlier. School records offer poignant glimpses into their lives. In the 2017 Christ Church annual report, Leon shared simple joys: “I liked playing in the block corner with [my friends]. I also liked exploring down at the river.”

The family had long advocated for better autism support. A 2015 newspaper article featured the Clunes among parents concerned about the closure of an intensive therapy clinic in East Fremantle offering specialized services. Maiwenna, originally from France and often called “Mai,” was active in online autism communities, sharing the realities of raising children with high support needs.

Friends and a former carer described the parents as exhausted and sleep-deprived, acting as primary caregivers with limited external help. Claims have surfaced that recent cuts to their National Disability Insurance Scheme (NDIS) funding left the family feeling “failed” by the system, exacerbating isolation and desperation.

The incident has triggered widespread grief and renewed debate over NDIS adequacy, carer burnout, and mental health resources for families with high-needs children. Federal Disability Minister Mark Butler called it an “unspeakable tragedy” but declined to discuss the family’s specific support levels. WA Premier Roger Cook described the deaths as “unimaginable” and “heartbreaking,” resisting immediate calls for a coronial inquest.

Disability advocates, including groups supporting neurodivergent parents, have urged systemic reforms. Tributes have flooded social media, with vigils planned and a moving poem honoring Leon and Otis shared by another mother of an autistic child.

This case highlights the profound pressures faced by caregivers in even privileged communities, where outward appearances mask deep crises.
