In the affluent, tree-lined enclave of Mosman Park, Perth’s most exclusive western suburb, a quiet morning on January 30, 2026, turned into one of Australia’s most shattering tragedies. Behind the closed doors of a family home on Mott Close, police uncovered the lifeless bodies of Jarrod Clune, 50, Maiwenna Goasdoue (Mai), 49, and their teenage sons Leon Clune, 16, and Otis Clune, 14—along with three beloved family pets: two dogs and a cat. What investigators have now labeled a double murder-suicide has left the nation reeling, but it is the chilling contents of a second suicide note—described as a structured “letter”—that have plunged the story into deeper darkness, revealing a family’s hidden torment that went unnoticed for far too long.

The first note was stark and final: taped to the front door, its message read along the lines of “Don’t enter. Call police.” A carer, arriving for a scheduled visit around 8:15 a.m., followed the grim instruction and dialed emergency services. Officers forced entry and found the family scattered in different rooms—no weapons in sight, no signs of struggle, but clear indications this was no accident. The deaths were swiftly classified as suspicious, with homicide detectives stepping in to treat the case as a murder-suicide: parents ending the lives of their vulnerable sons before turning on themselves.

But the real bombshell emerged later. Inside the home, investigators uncovered a second note—a detailed, heartbreaking document that has become the dark heart of the probe. Unlike the brief warning at the door, this letter allegedly spells out the parents’ joint mindset: years of crushing exhaustion, isolation, and despair that had built relentlessly. Sources close to the investigation describe it as a “manifesto” of suffering, containing not only the “why” but precise instructions on how the family’s finances should be handled after their deaths—bank accounts, assets, even guidance for any remaining affairs—underscoring a level of premeditation that chills to the bone.

At the core of the letter’s agony is a line that has haunted Australia: “They had been desperate for a long time…” Those six words capture the prolonged torment the family endured, a quiet cry for help that apparently went unheard. Leon and Otis both lived with severe autism and “significant health challenges,” requiring constant, intensive care that fell almost entirely on Jarrod and Mai. Friends and a former carer have painted a portrait of devoted parents who fought tirelessly for their boys, yet were repeatedly let down by the National Disability Insurance Scheme (NDIS): funding slashed, respite support denied, endless bureaucratic battles that left them “beaten down” and utterly alone. “The system failed them,” one carer declared, a sentiment now echoing across social media as carers and disability advocates share similar stories of burnout and despair.

The second note reportedly delves into this despair: the fear that no one else could ever provide the same unwavering devotion, the agonizing conviction that death was the only way to shield the boys from a future of institutionalization or abandonment. It suggests a joint decision between Jarrod and Mai, weighed in desperation after years of unseen suffering. Police have kept the exact contents under wraps to protect the investigation, but its existence has solidified the murder-suicide classification and transformed what might have been dismissed as a private tragedy into a national wake-up call.

The suburb remains in stunned silence. Neighbors who once waved hello now speak in hushed tones about the “quiet family” down the street. One resident recounted seeing Mai pushing the boys in wheelchairs on neighborhood walks, always smiling through visible exhaustion. “No one imagined it would end like this,” they told reporters. Others express guilt: Should someone have knocked when the faint crying echoed from the home the evening before? Could intervention have changed anything?

WA Premier Roger Cook labeled the incident an “unimaginable tragedy,” while police insist no threat remains to the community. Detectives continue combing the property, reviewing any available footage, and interviewing witnesses to reconstruct the final hours. Forensic pathologists work to determine precise causes of death, with early indications pointing to a non-violent method consistent with a planned, perceived-mercy act.

Across social media, the story has ignited a firestorm. Tributes pour in for Leon and Otis—described in old school newsletters as joyful boys who loved simple things like playing in block corners or exploring the river—now silenced forever. Friends remember Mai and Jarrod as tireless advocates, always championing their sons, yet constantly hitting walls when seeking help. “They fought every day for their boys to feel seen and heard,” one tribute read. But others turn their anger outward: at a broken system that allegedly pushed a family to the brink. Posts scream of government failure, with hashtags linking the case to broader NDIS cuts and the plight of carers for disabled children.

The second note— that haunting, intimate confession—holds the key to understanding not just what happened in Mott Close, but why a loving family could reach such a devastating conclusion. In Mosman Park’s manicured streets, the silence is deafening, broken only by whispers of a letter that explains the inexplicable… and warns that this family’s nightmare may be a symptom of something much larger.

As forensic teams continue their work and autopsies proceed, the investigation remains active. No ongoing threat exists to the community, police insist, but the ripple effects are far from over.
