Police in Windsor, Ont., have charged a driver involved in a fatal collision with a police cruiser.

On Oct.19, 2009, Nancy Theoret, 56, was killed when the car she was a passenger in collided with a police cruiser.

The officers were driving on Wyandotte Street East at Langlois Avenue on their way to Walkerville Collegiate responding to an emergency.

They intended to escort an ambulance carrying Senior Const. Mark Landry, 49, who had suffered a heart attack while playing basketball at the high school

Deborah Stein was driving the car carrying her friend, Theoret, along Langlois Avenue when it crossed into the path of the cruiser.

Both women were taken to hospital, where Theoret, a grandmother of five, was pronounced dead.

Two months after the accident, an independent review by the Special Investigations Unit determined the officer driving the cruiser was not criminally liable, and would face no charges.

Windsor police said Thursday that their investigation of the accident resulted in a charge of careless driving against Stein, who was driving the other vehicle. Stein is due in court at a later date to answer to the charge.
