Teen accused of killing his mother and two siblings in cold blood was in a ‘psychotic state’ when he was reportedly turned away from a hospital just hours before the alleged murders.

Teancum Vernon Petersen-Crofts has been charged with murdering his mother Michelle Peterson, 48, and his two siblings Bella, 15 and Rua, eight, at their Ellenbrook home in Perth’s northeast in the early hours of Sunday morning, shares Daily Mail.

The 19-year-old reported to St John of God Midland public hospital on Saturday night in a ‘psychotic state’, but was turned away when the police became involved, WA Today reported.

It is understood Petersen-Crofts was behaving erratically, but his condition was not considered to be a “medical problem”.

Petersen-Crofts faced Midland Magistrates Court on Monday..

During a reading of the charges, Petersen-Crofts spoke over magistrate Greg Smith a number of times.

He said he needed to speak because “mama is with me”.

“… I was painting a picture of Jesus and stayed there for two months. He punched me so hard in the head. So hard it wasn’t funny.”

When court security attempted to calm him, Petersen-Crofts lashed out at one of the guards.

“What are you looking at, serial killer? He looks like a serial killer and he’s a security guard.”

Due to concerns regarding Petersen-Crofts’ mental health, he was remanded on a hospital order for a week before his next court appearance.

Authorities claim Mr Petersen-Crofts called police to a 7-Eleven store in Ellenbrook in the early hours of Sunday.

The officers then discovered the confronting crime scene in a house just a few streets away where police found the bodies of the 48-year-old mother, Michelle Petersen, and her eight-year-old son, Rua.

  • This is so sad. The mental health system could sure do with an overhaul. There’s room for much improvement


  • Mental Health Patients can wait for days in an emergency department single room in a hospital while waiting for a bed in the mental health unit to be available.


  • The demand for services and care and support seem to be growing and this issue needs to be addressed. This is a tragic outcome.


  • Mental health is not taken serious enough in Australia. So many innocent lives lost needlessly because of the mental state of one individual.


  • So sad for this family, we need better resources all over!


  • It happened lately with that guy that went home and killed his young son. And now this! :-(


  • The family could have been alive if he was taken into the hospital.


  • This happens way too often, medical staff need more resources and more training to get help to people who need it before it’s too late.
