Police probe whether Courtney Paige Anderson jumped from her car on the Bruce Hwy, Queensland

Investigators will probe whether a 28-year-old woman jumped from a moving vehicle before she died on a major highway.

Police will investigate whether a young woman who died on the side of a major Queensland Hwy jumped from a moving vehicle.

Courtney Paige Anderson, 28, was travelling along the Bruce Hwy in Bajool, south of Rockhampton, with her 35-year-old partner on Easter Monday when the “unexpected and sudden” incident occurred.

Ms Anderson was found 80m from the Toyota HiLux she was travelling in.

Courtney Paige Anderson, 28, has been identified as the woman killed on the Bruce Hwy.

Detective Acting Senior Sergeant Kevin Mawdsley said investigators have spoken to a number of people who witnessed the aftermath of the incident.

“We still don’t have anyone who’s contacted us, who’s sighted the vehicle driving Monday afternoon,” he said according to The Morning Bulletin.

“All our sightings are post incident (when) the car is stationary on the side of the road.

“She sustained catastrophic injuries and she lost her life but I won’t comment at this point in time about how those injuries were sustained,” he said.

Det Mawdsley said some incidents between Ms Anderson and her partner had been reported to police but noted police had had no contact with the couple for some time until her death.

“There are some previously reported incidents but nothing recent. I won’t elaborate as to the specifics of that, we want to speak with the family members and other loved ones of these two persons to ascertain if there are any … issues which need to be considered.”

Det Mawdsley confirmed Ms Anderson’s partner was taken to Rockhampton Hospital, where he was treated for shock.

“A number of witnesses who were travelling on the highway who stopped to render assistance all gave consistent versions that he was very distraught and highly emotional and that he needed to be treated for shock-type symptoms.’

Det Mawdsley said he is co-operating with police.

The detective noted Ms Anderson’s family are “devastated” by her death.

“When a death occurs in that category it obviously is devastating for the family,” he said.

“It’s going to be a difficult day for the family … there is going to be a lot of questions we probably can’t answer in full.”
