What Police Say About the Notes Left in Mosman Park Murder-Suicide Investigation

 MOSMAN PARK, WA — Police are investigating a second note found inside the upscale Mosman Park home where Jarrod Clune, 50, his partner Maiwenna Goasdoue, 49, and their teenage sons Leon, 16, and Otis, 14 were discovered dead Friday morning in what authorities are treating as a double murder‑suicide.

Officers were called to the Mott Street property around 8:15 a.m. after a caregiver arrived for a scheduled visit and spotted a warning note advising against entry, Acting Detective Inspector Jessica Securo said. Inside, police found the family — along with their three pets — in different parts of the house. Authorities described the scene as “highly distressing,” noting there were no signs of forced entry or struggle.

Neighbors told media that both boys had severe autism, significant health challenges, and were non‑verbal. Investigators later discovered a second letter inside the residence, which reportedly outlined the parents’ mindset and suggested planning behind the tragedy. According to local reports, the note indicated the couple had jointly decided to end their lives, overwhelmed by the challenges of caring for their sons.

Sources close to the family said they had struggled to receive adequate support from government agencies and disability providers. The revelation has sparked renewed discussion about the pressures faced by families caring for children with complex needs.

WA Premier Roger Cook called the deaths an “unimaginable tragedy,” especially the loss of two innocent children, urging those in crisis to seek help. Autism Association of WA CEO Joan McKenna Kerr expressed deep grief and emphasized the availability of support hotlines for affected families.

The incident has shocked the tight‑knit Mosman Park community, where the Clunes were known as devoted parents. Police continue to investigate the circumstances, with post‑mortems pending to determine how the teenagers died. Authorities are appealing for information as the homicide probe remains active.
