THE learner driver who killed a young woman and injured 11 other pedestrians when she crashed through a Sydney bus stop on Tuesday remained in hospital last night, as police waited to interview her.

The 42-year-old, who screamed hysterically after the fatal crash at Kogarah, in Sydney’s south, is in a satisfactory condition in St George Hospital, receiving treatment for shock.

A man calling 2GB radio, claiming to be the brother of the man accompanying the learner driver, said the mother of five might have hit the accelerator instead of braking at traffic lights.

“It went to amber and instead of putting on the brakes, she put her foot down,” he said.

Four other people, including an 18-month-old boy, remain in hospital.

Flowers appeared at the crash site in memory of Emma Hansen, 20, a fashion student at St George College who died as a result of her head injuries.

College director Dianne Craven described Ms Hansen as a promising student.

“All the staff and students are deeply shocked and we want to send our condolences to Emma’s family and friends,” Ms Craven said.

Ms Hansen’s former high school principal in the NSW regional city of Orange, Rodney Hancock, said her “beautiful smile and gentle manner made her much loved”.

Local shopkeepers told of their concerns about the intersection.

Harry Johnson at Ulysses Charcoal Chicken said accidents would continue until red arrows were installed at the lights.

But Kogarah mayor Michael Kitmiridis said that while the safety of the intersection would be reviewed, it was the first accident involving a pedestrian at or near the crash scene in 10 years.
