Police are awaiting medical clearance before they can question the mother of the 23-year-old tertiary school student who died in a road accident near Namau along the Nabouwalu Highway last Sunday night.
The mother sustained serious injuries in the accident and has been admitted in the hospital.
According to Police, the four people were heading towards the Nabouwalu Jetty when the mother allegedly lost control of the vehicle causing it to veer off the road and tumble several times.
Police say they were all rushed to the Nabouwalu Hospital where the woman was pronounced dead on arrival.
The national road death toll currently stands at 36 compared to 55 for the same period last year.
