What began as a routine visit to a family home in Perth’s leafy Mosman Park quickly turned into a tragedy that has left loved ones, neighbours, and first responders reeling.
By mid-morning on Friday, police were piecing together what they now believe was a devastating double murder-suicide involving a family of four.
Who the Family Were
Authorities have identified the deceased as Maiwenna Goasdoue, 49, her partner Jarrod Clune, 50, and their two teenage sons, Leon, 16, and Otis, 14.
The family lived in Mosman Park, one of Perth’s most affluent suburbs, known for its quiet streets and proximity to beaches like Cottesloe.
Their bodies were discovered inside the home after a care worker, scheduled for a pre-arranged visit, arrived around 8.15am and became concerned.
A note found at the property reportedly warned the visitor not to enter and instead contact police.
The Moment Police Entered the Home
When officers arrived and went inside the house, they found the family members in different areas of the property.
Two dogs and a cat were also found dead.
Emergency services were called shortly after, with St John WA confirming five ambulance crews attended the scene at 8.29am.
Police quickly secured the area, closing surrounding streets as forensic teams began their work.
Detectives have since said there is no ongoing risk to the public.
A Family Living Largely Out of Sight
Friends say Maiwenna, known as “Mai” to those close to her, was deeply devoted to her children.
Originally from Morlaix in Brittany, northwest France, she had spoken openly in online support groups about her sons’ disabilities, explaining they were on the more severe end of the autism spectrum.
According to people who knew the family, caring for the boys required constant attention and specialist support.
One care provider had been regularly assisting them, highlighting just how intensive daily life had become inside the home.
School Memories and Community Shock
Both boys were understood to have attended Christ Church Grammar School, where their father Jarrod was also educated.
A school newsletter from 2023 marked Otis’s departure, with a teacher praising his enthusiasm, communication efforts, and participation in group activities.
Students who recognised Leon from school described the news as heartbreaking and difficult to process, saying it was “really sad” and completely unexpected.
Friends Describe Overwhelming Pressure
Close friend and fellow parent Nedra spoke emotionally about the couple, describing them as loving, protective, and entirely focused on their sons’ wellbeing.
She said the family faced relentless challenges trying to secure reliable and appropriate care, especially for one child who needed constant, high-level support.
According to Nedra, the couple often felt cut off from support systems, including schools, health services, and the NDIS.
The fear of their children being mistreated meant Mai was reportedly unwilling to place them in respite care, even when exhaustion set in.
“Beaten Down by the System”
Another family friend, who asked not to be named, echoed those sentiments, calling Mai and Jarrod a strong, united couple who did everything possible to protect their boys.
They described years of seeking help from therapists, schools, and medical professionals, often only to be turned away.
The friend stressed this was not a case of domestic violence, but rather a tragedy shaped by isolation, burnout, and fear about what the future might hold for their children in a system they felt repeatedly failed them.
What Police Are Saying Now
Detective Acting Inspector Jessica Securo confirmed investigators are treating the deaths as a suspected double murder-suicide.
She said no weapon was used and there was no known history of family violence involving those at the home.
She described the scene as “highly distressing” and acknowledged the significant health challenges faced by the teenage boys.
While the investigation is still in its early stages, police have made it clear there is no threat to the wider community.
A Broader Conversation Left Behind
Beyond the immediate grief, friends say the tragedy raises painful questions about inclusion, disability support, and how families coping with complex needs are supported — or left to cope alone.
For those struggling after hearing about the incident, help is available.
Lifeline can be reached on 13 11 14 for confidential support at any time.
What Happens Next
Western Australia Police remain at the Mosman Park property as forensic examinations continue.
Investigators will compile reports for the coroner, who will ultimately determine the official cause and circumstances of the deaths.
For now, a once-quiet suburb — and two extended families across Australia and France — are left grappling with a loss that feels impossible to fully comprehend.
