Ms White died at the scene, while her granddaughter, who saw the horror unfold, was unhurt.

Detectives earlier released CCTV footage of four youths in a Hyundai Getz, allegedly belonging to Ms. White was stolen.

“Unfortunately the motive was to steal a Hyundai Getz,” Queensland Police Acting Superintendent Heath McQueen said of the fatal stabbing.

“I stand before you today and talk to you about a murder of a grandmother in front of a six-year-old … and the result was a stolen Hyundai Getz – that is the motive.”

He described it as a ‘callous, cowardly, violent crime’.

“She was a loving family woman,” he said.

‘She took her granddaughter to the shops. This is senseless violence.’

In the wake of Ms. White’s death, one of her granddaughters, Samantha White, created a petition call for tougher laws and penalties for gang-related and racially motivated violence.

“This devastating event made me realize how urgent it is to address gang-related and racially motivated violence in our community,” Samantha wrote.

‘It is a harsh reality that such incidents are not isolated, but are part of a growing trend.’

She said gang violence had soared in recent years, citing figures from the Australian Institute of Criminology.

“We need tougher laws and tougher penalties for these heinous crimes,” the petition continued.

‘We need reforms that will make our streets safer and ensure that no other family has to endure the pain we are experiencing.

‘This petition calls on legislators in Redbank Plains QLD, Australia, to take immediate action by implementing tougher laws against gang-related activity and racial violence, as well as imposing tougher penalties on those found guilty of such acts.

“Help make everyone’s lives safer sign to make Vyleen’s law possible.”
