A mother driving her daughter to have her hair done on her 16th birthday died of multiple injuries when a police vehicle chasing a stolen car slammed into her at high speed, a court has been told.
The first class constable who was driving the police car, who cannot be identified for legal reasons, has gone on trial in a Perth court charged with dangerous driving causing the death of Sharon D'Ercole.
The 50-year-old was in her Toyota Corolla, driving her daughter Lashay to a hair appointment in the Perth CBD, when her car was smashed into by the Ford Territory at the intersection in Dianella in April 2012.
Perth District Court heard the Ford had gone through two sets of red lights when it smashed into Ms D'Ercole's car, causing her horrific injuries.
The mother-of-three died less than an hour later in hospital.
Prosecutor Bernard Standish told the jury they would have to decide just one major issue - whether the constable's driving was dangerous to the public.
"The lives of Sharon D'Ercole and this officer intersected with tragic consequences," Mr Standish said.
The court heard the 28-year-old officer was trained to the highest level of pursuit driving. He had set off after the stolen Audi after police database checks indicated it had been stolen just hours before.
The car's lights and sirens were deployed as the pursuit progressed, the court was told.
The trial, which is scheduled to last three weeks, will hear from several eye witnesses, as well specialists who will estimate what speed the cars were doing when they collided.Ms D'Ercole's daughter however, will not be giving evidence, as she was knocked unconscious in the crash and has no memory of the moments leading up to her mother's death.
