Tragic Mosman Park Deaths: Suspected Murder-Suicide Highlights NDIS Failures and Caregiver Burnout

Perth, February 3, 2026 — The quiet cul-de-sac of Mott Close in affluent Mosman Park was shattered last Friday when a support worker arrived for a routine visit and discovered a note on the front door reading, in effect, “Don’t enter. Call police.” Inside the $3 million family home lay the bodies of Jarrod Clune, 50, Maiwenna “Mai” Goasdoue, 49, and their teenage sons Leon, 16, and Otis, 14 — alongside three family pets. Police have classified the deaths as a suspected double murder-suicide, with both boys believed to have been killed by their parents before the couple took their own lives.

A second note, discovered inside the home over the weekend, is understood to outline financial arrangements for after the family’s deaths and suggest the parents made a joint, premeditated decision to end their lives together. No floorboard discoveries or dramatic 2:14 pm revelations have been reported by authorities or mainstream media; social-media posts claiming otherwise appear to be fabricated sensationalism.

Forensic officers and police sealed the property as they worked through the scene.

The family had been under immense strain. Both Leon and Otis lived with autism and “significant health challenges,” requiring full-time care. Former support workers and friends have spoken publicly of exhaustion, sleep deprivation, and repeated pleas for more NDIS funding that went unanswered. One carer told media the family felt “failed” by the system, with funding cuts leaving them without adequate respite or overnight support.

School records obtained by 7NEWS paint a different picture of the boys — cheerful, social youngsters who loved friends, activities, and everyday childhood joys. Yet both had faced challenges: one was reportedly expelled and once described in records as a “monster,” a label that deeply upset the family. Maiwenna, French-born and known as “Mai,” was active in autism support groups and openly described her sons’ autism as “severe.”

WA Premier Roger Cook called the deaths an “unimaginable tragedy.” Disability Minister Mark Butler described it as “unspeakable” but declined to comment on the precise level of NDIS support the family received. The Australian Neurodivergent Parents Association held a candlelit vigil and released a moving poem honouring Leon and Otis: “You belonged. You were children… All they wanted was to be understood.”

Jarrod’s father, the boys’ grandfather, returned to the property over the weekend, visibly devastated. Tributes — flowers, teddy bears, handwritten messages — continue to pile up at the end of Mott Close, which was reopened to residents on Monday.

Family’s health battle before murder-suicide – Yahoo News Australia

Forensic officers leave the Mott Close property after processing the scene.

Police have confirmed they are still investigating but say there is no ongoing threat to the public. Autopsies are expected to confirm cause of death in coming days. The case has reignited calls for urgent NDIS reform, particularly for families with high-needs children. Advocates say thousands of Australian families are one crisis away from breaking point, with insufficient respite care, funding delays, and mental-health support for exhausted parents.

Maiwenna and Jarrod were remembered by friends as devoted, loving parents who fought every day for their boys. “They were at breaking point,” one former carer said. “They loved those boys more than anything, but the system just wasn’t there.”

As the community mourns, the second note — the one that helped investigators conclude the deaths were a planned act — remains private. What is clear is that four lives, two of them young and full of potential, ended in a quiet Perth street because a family felt they had nowhere left to turn.
