A man, a woman and their teenage children have been found dead in their home in what police are treating as a double murder-suicide.

The 50-year-old man, a 49-year-old woman and two boys, aged 14 and 16, were found dead at their home in the Perth suburb of Mosman Park on Friday morning.

Three pets were also found dead at the home.

There was no weapon used in the incident and police had no record of family violence matters involving the family, homicide detective Jessica Securo said.

“Although this investigation is in its infancy, police are investigating this matter as a murder-suicide,” Securo told reporters.

“There is no ongoing risk to the community.”

Both children had experienced “significant health challenges”, and the family had previously engaged with care services, Securo said.

A cause of death is yet to be revealed, but a note was found at the home, she said.

The suspected double murder-suicide in Mosman Park, Perth, on January 30, 2026, that claimed the lives of Jarrod Clune (50), Maiwenna Goasdoue (49), and their sons Leon (16) and Otis (14), along with three family pets, continues to unfold with new witness and evidence details. A resident living two houses away has come forward to police, admitting they heard an unusual sound after midnight—approximately 30 minutes before the estimated time frame of the incident based on forensic timelines. The sound was not screaming, not arguing, but something indistinct and unexplained that left the neighbor unsettled. Crucially, CCTV from the area (likely a neighbor’s security camera or nearby footage) recorded it, providing investigators with an audio-visual clue that is now under close analysis.

The Unusual Sound: What Was Heard

The neighbor, speaking to authorities and referenced in investigative updates, described the noise as occurring sometime after midnight in the early hours leading into January 30. It was a singular, anomalous event—perhaps a thud, bang, mechanical-like hum, or other non-vocal disturbance—that stood out in the otherwise quiet, affluent Mott Close neighborhood. The resident emphasized it did not resemble typical household sounds (e.g., doors slamming, raised voices, or pet activity) and did not prompt immediate concern at the time, given the suburb’s peaceful reputation.

Timing: Placed roughly 30 minutes prior to when police believe the fatal acts occurred (exact time of death awaits autopsy confirmation, but evidence points to overnight hours after family routines ended).
Character: Explicitly not human distress (no cries, yells, or arguments), ruling out immediate conflict escalation. This aligns with the suspected premeditated nature, where the tragedy unfolded silently or with minimal audible disruption.
CCTV capture: Footage from a nearby property (possibly doorbell camera, driveway security, or street-facing system) coincidentally recorded the audio portion of the sound, along with any visual context (e.g., lights, shadows, or movement at the home). Homicide Squad detectives are reviewing this alongside other CCTV canvassed from the area to reconstruct the final hours.

This detail has prompted renewed neighbor interviews and forensic audio analysis. In quiet residential settings, such unexplained noises—especially when timed close to a tragedy—can indicate preparatory actions (e.g., moving objects, vehicle activity, or environmental factors) or the moment of impact in non-violent methods (no weapons were used, per police).

Broader Scene and Investigation Context

The bodies were discovered around 8:15 a.m. on January 30 when a carer arrived for a scheduled visit, found a visible note (“don’t enter, call police”), and alerted authorities. A second hidden message (as previously reported) has reshaped timeline understanding, particularly the last 30 minutes, suggesting detailed planning.

Police have stressed:

No prior reported family violence or external threats.
The boys had significant health challenges (understood to include severe autism requiring intensive care), contributing to long-term caregiver strain.
The incident appears premeditated, with notes and scene evidence pointing to the parents’ involvement in ending the lives of their sons and themselves, followed by the pets.
Detectives are examining all CCTV, including this new audio capture, to pinpoint sequences without relying solely on witness recall.

Neighbors describe the family as devoted but increasingly isolated, with exhaustion from NDIS gaps and limited support. A former carer claimed the family felt “failed” by systems, highlighting broader caregiving crises.

Community Shock and Reflections

The suburb remains in mourning, with schools and locals sharing tributes to Leon and Otis—described as loved despite challenges. Premier Roger Cook called it “heartbreaking,” urging better mental health and disability support.

The unusual sound—captured on CCTV yet defying easy explanation—serves as a haunting auditory marker of the final quiet hours in a home that once held laughter (as relatives recalled in recent calls). It underscores how tragedies can unfold invisibly in plain sight, leaving only faint echoes for those nearby.

Anyone with additional footage or information is urged to contact WA Police. Support resources include Lifeline (13 11 14) for those affected.
