The woman accused of killing two children when her car reversed through the doors of a London Costco has entered a plea of not guilty to all charges.
Ruth Burger, 65, faces two counts each of criminal negligence causing death and criminal negligence causing bodily harm.
She was behind the wheel of a car that reversed through a south London Costco in July 2014, hitting a pregnant mother and her children.
Addison Hall, 6, died as a result of the incident. The mother, Danah McKinnon-Bozek was severely injured in the crash and had to have an emergency c-section. She gave birth to a baby girl, who died a week later.
The judge must determine whether Burger is just factually responsible or criminally responsible.
She told witnesses at the scene that her flipflop got stuck underneath the gas pedal when she reversed through the doors. Photos of the slip-on shoes Burger was wearing at the time of the crash were presented to the judge. A black smudge can be seen on the top of the right shoe.
Cst. Trevor MacDonald was the first to testify. He told the court Burger's car accelerated from 11km/h to 46km/h in the five seconds leading up to the crash. She never hit the brakes during that time.
Both lawyers agree the 65-year-old was in good mental and physical shape at the time, and her Chevrolet MonteCarlo was fine.
Other shoppers and employees who witnessed the crash say they heard a car engine rev, then a loud crash. They describe the scene inside the store as pure chaos.
It is expected the trial will last five days. It will resume tomorrow at 10am.
Video of the crash and the aftermath, filmed from inside the Costco on Welington Rd., will be presented as evidence.
