One of the two toddlers critically injured after a dump truck ploughed into multiple vehicles has died in hospital.

Emergency crews raced to the scene in Banya on Queensland‘s Sunshine Coast about 11.40am last Thursday after a Mitsubishi Fuso truck collided with a silver Nissan Qashqai.

The truck continued along Banya Avenue before crashing into the rear of a blue Haval station wagon, stopped at traffic lights at the intersection with Great Keppel Way.

Two vehicles in front of the station wagon, were also struck.

Ineza was airlifted to Queensland Children’s Hospital, where she lost her fight for life on Wednesday.

Her little sister remains in a critical condition in the same hospital.

Their mother was also injured but has since been released from hospital.

Ineza and her sister Itahe, 1, were in the back seat of a station wagon that was hit by the truck

Off-duty doctor Marcio Brussius Coelho raced to the scene and provided first aid to Ineza until an emergency helicopter arrived.

‘Quite, I’d say, emotional as a father and having kids that age as well,’ Mr Coelho told Seven News last week.

‘But at the moment, you just have to do what you need to as a doctor.’

Forensic Crash Unit investigations into the circumstances surrounding the crash are ongoing.

Anyone with information or footage is urged to call Crime Stoppers.
