In a tragic incident in Perth’s western suburbs, authorities have discovered the bodies of two adults and two teenage boys in what is currently being treated as a murder-suicide.

The discovery was made when police responded to a call at a Mosman Park residence around 8:15 a.m. local time. The call was made by someone familiar with the family who had grown concerned for their safety.

Upon entering the home, officers found the deceased, identified as a 50-year-old man, a 49-year-old woman, and two boys aged 14 and 16. Additionally, two dogs and a cat were found dead at the scene.

Authorities confirmed that the individuals were members of the same family, noting that the children had faced “significant health challenges” in their lives.

“The investigation is still in its preliminary stages,” stated WA Police Detective Acting Inspector Jessica Securo, “but we are currently treating this as a murder-suicide case.”

Inspector Securo added, “This heartbreaking event just unfolded this morning, and it will require time for us to thoroughly investigate the circumstances surrounding these deaths.”

Securo said no weapon was during the incident and the family had no reported family violence matters and were not known to police at all.

She said a note was left at the premises.

“We do know that both children experienced significant health challenges,” she said.

“This is a highly distressing situation for all involved, from community members to the person who located the family to our first responders.

“WA police force has engaged our health and welfare and support services for all our front-line staff who attended this incident.

“If this incident has adversely affected or impacted you, I urge you to speak to your loved ones and get some help and assistance.”
