Tragic Mosman Park Murder-Suicide: Second Note Reveals Parents’ Desperate Mindset Amid Overwhelming Caregiving Struggles

In a heartbreaking development from Perth’s affluent Mosman Park suburb, Western Australia Police have confirmed the discovery of a second note at the family home on Mott Close, where a suspected double murder-suicide claimed the lives of parents Jarrod Clune, 50, and Maiwenna Goasdowe, 49, along with their teenage sons Leon Clune, 16, and Otis Clune, 14. Three family pets—two dogs and a cat—were also found deceased at the property on Friday morning, January 30, 2026.

The tragedy unfolded when a support worker, arriving for a scheduled visit to provide care for the boys, discovered a note on the front door urging not to enter and to call police immediately. Authorities arrived around 8:15 a.m. to find the bodies in different parts of the home. Homicide detectives, led by Detective Acting Inspector Jessica Securo, quickly classified the incident as a double murder-suicide, emphasizing there was no indication of violence at the scene.

A first note served as a warning, but the second—described as a structured “letter”—provided crucial insights into the family’s mindset. It allegedly detailed the parents’ joint decision, levels of planning (including post-death financial arrangements), and reasons behind the act. Police have withheld specifics, stating the ongoing investigation will determine the exact timeline of when the family was last seen alive and the precise cause of death.

Family and friends painted a picture of profound desperation. Jarrod and Maiwenna were characterized as overwhelmed primary carers for their sons, both living with autism. One boy reportedly faced more significant neurodevelopmental challenges than his brother, intensifying the daily pressures. Close associates said the couple felt “desperate for help” and exhausted, coping as best they could amid insufficient support from government agencies and disability providers.

Detective Securo confirmed the family had previously accessed care services, though the parents bore the primary responsibility. “The family had engaged with care services but I’ll leave it at that at this stage,” she told media on Friday. The boys’ “significant health challenges” were acknowledged, underscoring the immense strain on the household.

The discovery has shocked the community, with WA Premier Roger Cook describing it as an “unimaginable tragedy” and “heartbreaking.” Tributes have poured in, including calls for Australians to light candles at 5 p.m. to honor Leon and Otis—described in school records as cheerful and appreciated students. Friends remembered the parents as loving, yet visibly worn by caregiving demands.

Forensic teams remained at the scene for hours, with officers in protective suits cordoning off the modern double-storey home in the leafy, upscale neighborhood. The absence of violent indicators suggests a non-confrontational method, though autopsies and toxicology will provide clarity.

This case highlights the often-hidden crises faced by families caring for children with complex needs. Advocates have long called for better resourcing of autism support, respite care, and mental health services to prevent such devastating outcomes. As investigations continue, the focus remains on understanding the full circumstances while respecting the family’s privacy.

The community mourns the loss of a once-vibrant family, with many reflecting on the toll of unchecked exhaustion and inadequate systemic aid. Police urge anyone with information to come forward as they piece together the final days of Jarrod, Maiwenna, Leon, and Otis.
