A second handwritten letter discovered inside the Mott Close home in Mosman Park has shifted the narrative of Perth’s most heartbreaking family tragedy. Handwriting experts have confirmed it was penned by Jarrod Clune, 50, leading police to believe he may have single-handedly orchestrated the events that claimed the lives of his partner Maiwenna Goasdoue, 49, their sons Leon, 16, and Otis, 14, along with the family’s two dogs and cat on January 30, 2026.

The discovery unfolded when a support worker arrived for a routine visit and spotted a warning note taped to the front door: words urging not to enter and to call police immediately. Officers forced entry around 8:15 a.m. to find the four family members deceased in separate areas of the upscale property. The pets were also found dead, adding to the scene’s profound sorrow. Initial reports classified the incident as a suspected double murder-suicide, with homicide detectives investigating the boys’ deaths as homicides allegedly perpetrated by their parents before the adults ended their own lives.

While the exterior note served as a grim alert, the interior second letter—structured formally like a last will or explanation—provided critical insight. It detailed the family’s financial wishes post-death, expressed deep parental overwhelm from years of caregiving, and outlined the mindset leading to the act. Early interpretations suggested a joint parental decision amid extreme despair. However, forensic handwriting analysis has reportedly matched the document exclusively to Jarrod Clune, prompting investigators to reassess whether the plan was unilateral. Sources indicate phrases implying dissent—”not everyone agreed with this plan”—hint that other family members may not have consented, raising questions of secrecy, possible coercion, or isolated desperation in Jarrod’s final actions.

The Clune-Goasdoue household had been under immense strain for over a decade. Both Leon and Otis lived with severe, non-verbal autism and complex health needs requiring constant, round-the-clock care. Former school accounts described the boys as joyful and engaged in their younger years, participating in activities and forming friendships. As teenagers, challenges escalated: one boy reportedly faced school expulsion and harsh labeling, contributing to family isolation. Relatives and former carers described the parents as increasingly withdrawn, feeling abandoned by inadequate disability services, NDIS limitations, and societal support gaps. Exhaustion, sleep deprivation, and emotional burnout dominated their reality, with little respite available.

Maiwenna, originally from France, and Jarrod appeared devoted partners in public glimpses—online profiles showed family moments without overt red flags. Yet privately, the load proved crushing. The inclusion of the pets in the tragedy underscored the all-encompassing nature of the despair, as if no part of their shared life could be left behind. Friends insist the parents loved their sons fiercely, making the outcome all the more incomprehensible.

Western Australia Police have treated the case with sensitivity, declining to release full letter contents pending the coronial inquest. The handwriting confirmation has intensified focus on Jarrod’s role: was untreated mental health decline, overwhelming hopelessness, or perceived lack of alternatives the driving force? No external involvement has been suggested, and the investigation continues toward a coroner’s report.

The tragedy sparked immediate community and political response. A vigil at Gibbon Park drew dozens, including Mayor Paul Shaw, who noted the need for collective processing amid shock. Disability advocates, including Commissioner Rosemary Kayess, expressed heartbreak and called for urgent reforms. Premier Roger Cook labeled it “unimaginable,” while Disability Services Minister Don Punch faced parliamentary scrutiny over support shortfalls for high-needs families. Stories from other carers—like a Kalgoorlie mother highlighting “light at the end of the tunnel” through persistence—emerged as beacons amid grief.

This case exposes the silent epidemic facing caregivers of profoundly disabled children: burnout, isolation, and the terrifying perception that no help exists. In affluent Mosman Park, behind manicured lawns, a family crumbled under invisible weight. The boys—Leon energetic and kind, Otis gentle and loving—deserved protection, not this end. Their parents, once pillars of devotion, succumbed to a darkness that overshadowed everything.

As Perth mourns, the second letter’s revelation forces uncomfortable questions: How many more families teeter on the edge without adequate lifelines? Enhanced respite, mental health access, NDIS improvements, and community outreach are urgently needed. The Clune family’s story, etched in sorrow, demands we listen before more homes fall silent.
