Shocking development after a retired teacher was stabbed to death in Brisbane shopping centre

Four 'persons of interest' in the carjacking death of a 70-year-old retired religious teacher have been photographed by police in a desperate bid to track down those responsible for her murder.

Vyleen White, 70, was stabbed to death in the underground car park of the Town Square Redbank Plains Shopping Centre, in Brisbane's south-west, about 6.10pm on Saturday.

Her six-year-old granddaughter witnessed the horror attack and screamed for help as the knifeman fled in her grandmother's blue 2009 Hyundai Getz.

Ms White's stolen car was later found in Springfield Lakes and seized for forensic examination.

Detectives from Ipswich and the Homicide Investigation Unit released CCTV images of four people they believed could assist their investigation on Sunday.

The group is described as possibly a mix of adult and young men who appear to be African.

“Investigators believe the four people depicted in the vision, captured last night in Bruny Street, Springfield Lakes, may be able to assist them with their investigation,” Queensland Police said.

“The vision also shows an interesting vehicle previously mentioned in an earlier press release, a blue 2009 Hyundai Getz with Queensland registration 432 TYO.”

Investigators urged anyone who saw the group in the Redbank Plains and Springfield Lakes areas between 6pm and 7pm on Saturday to contact police.

People with relevant camera footage and dashcam footage were also asked to come forward.

Mrs. White's daughter, Danice White, revealed that the grandmother was grocery shopping downtown ahead of plans for a Bible study later Saturday evening.

“We're all quite numb and shocked, we have high blood pressure at the moment,” Danice said Courier mail of her family.

“I'm having trouble controlling my thoughts right now.”

Danice recalled her father telling Mrs. White to go to another shopping center before she was attacked.

'Dad said, “Why don't you go to Redbank Plaza?” “If she had just listened that day, it wouldn't have been her,” she said.

The 70-year-old retiree is remembered as a kind-hearted man with a dedication to helping others, especially the homeless.

She was about to celebrate her 50th wedding anniversary with her husband, who relied on her help to navigate the world after he went blind.

Local doctor Ademola Afolabi was the first person to arrive at the confrontational scene of the stabbing.

He had heard Mrs White's granddaughter shouting: 'My grandma is dead' and followed her from outside Aldi into the car park.

“I saw a lady in a pool of blood, she was unresponsive, so I called triple-0,” he said.

“Her pants were soaked in blood, probably bleeding from the chest area.”

Mr Afolabi said it was “too late” to help Ms White by the time paramedics arrived, adding that her attacker “didn't give her a chance”.

Detective Acting Chief Inspector Heath McQueen asked for the public's help on Sunday afternoon in identifying the four people who “dumped the victim's vehicle on the street at Springfield Lakes, got out of that vehicle and walked away.”

“I can say that there is believed to be one person involved in the attack on this elderly lady, operating alone,” he said.

“However, it is possible that we may identify additional perpetrators peripherally connected to this perpetrator who committed the murder.”

Detective Acting Chief Inspector Heath McQueen described the stabbing as a 'heinous, cowardly, violent attack' and appealed for the public's help in identifying the four people (pictured) seen leaving Ms White's stolen car.

Supt McQueen described the scene on Saturday as 'very harrowing' and acknowledged that although Ms White's six-year-old granddaughter was unharmed in the attack, it will 'leave a scar on her'.

“Let's be clear: this is a disgusting, cowardly, violent attack on a 70-year-old grandmother in front of her six-year-old granddaughter,” he said.

“This is a very confronting scene that we had to deal with tonight.”
