Police certain speed was a factor in fatal crash
POLICE remain certain speed was a likely factor in a quadruple fatality on Mooloolah Connection Rd.
Acting Superintendent John Boznjack said investigations into the accident at Glenview on Friday night were continuing, but if Keisha Ann Jackson was travelling to the speed limit of 80kmh, police were confident she would have survived the bend.
"I get sick of hearing arguments about roads," he said.
"The roads aren't that bad if you drive to them.
"I'd still struggle to see how you'd have trouble going around that corner even doing 80kmh in the rain. That's my personal opinion."
Ms Jackson, 30, died on impact. Her 10-year-old son Ryan Jackson-Cook and seven-year-old daughter Joan Jackson died at the scene.
Four-year-old daughter Matilda Jackson-Cook died on Sunday night after her life support was turned off at Royal Brisbane Hospital.
Eathan Jackson, 12, was the sole survivor and has been in the care of grandparents from Townsville.
Central Region assistant commissioner Mike Condon said police were conducting a post-mortem investigation of the driver and waiting on toxicology reports to provide a better understanding of what happened - "why tragically we've lost so many innocent lives in one incident".
Act Supt Boznjack said officers hoped to have a better picture within the next week about the car's speed and whether the children were wearing seatbelts.
"There was some speculation about that but we will run our inquiries," he said.
"We have no actual witnesses to the incident itself.
"We do have witnesses who live nearby that actually heard the vehicle. It appears that speed is a factor in this fatality."
Act Supt Boznjak said the Wurtulla family was heading south towards Steve Irwin Way but the reason for their trip was still unknown.
"There have been certain scenarios that we need to run past the child (Eathan)," he said.
Act Supt Boznjak will meet with the extended family this morning.
