Homicide Detectives Investigating 'All Angles' Of Horror QLD Crash

Charmaine Harris McLeod and her four young children Aaleyn, Matilda, Wyatt and Zaidok were killed earlier this week when their car collided in a fiery crash with a truck on Queensland's Bunya Highway.

On Friday, Police Commissioner Ian Stewart confirmed homicide detectives had now also joined the investigation.

Stewart said police were looking at "all angles" of the crash when asked to explain why the family had not been added to the official road toll this week.

He said there were very specific rules about traffic crashes that occur.

"There are very different rules, and that's why we now have homicide detectives working on this case where there is a potential there was an intention for someone to die," Stewart said.

"This will take some time and obviously the coroner has a very great interest in the outcomes of the investigation."

"But no matter what happened, no matter why it happened, it's a tragedy for all those involved and for the Queensland community."

A spokesperson for Queensland Police confirmed to 10 daily that the possibility the crash was deliberate was not being ruled out by investigators, but insisted the investigation was in its early stages.

Charmaine and three of her children were pronounced dead at the scene after emergency services responded to reports a Nissan Station wagon had collided head-on with a semi-trailer north-west of Brisbane.

A fourth child managed to escape the wreckage and she was transported to Kingaroy hospital and then onto Brisbane. She died during the flight to Brisbane.

James McLeod, the father of the four children who were aged between just two and six-year-old, released a statement earlier this week saying he would miss them with all of his heart.

"They were beautiful souls and were loved by all who knew them."

The tragic deaths of the family have devastated their home community of Eli Waters, near Hervey Bay.

Ally and Matilda's school in Hervey Bay, Kawuagan Public School, issued a statement following the deaths of two of their youngest students.

"They were both joyful and friendly children who will be greatly missed by all their friends and family," the statement said.

He lost control of the car, drove through the closed garage door and across the street, hitting a parked car on the other side of the road and crashing into the power pole.

He was taken to the Gold Coast University Hospital for treatment for lacerations on his head and knee, but died on Friday morning.
