MISSISSAUGA, Ont. -- The province's police watchdog says two provincial police officers are facing charges following an investigation into the death of an 18-year-old woman last October.

The Special Investigations Unit says officers were conducting a RIDE program in Burford, Ont., on Oct. 10, 2014, when a pickup truck didn't stop.

The pickup entered Brantford, Ont., where it collided with a car driven by Ashley Lerno, who died of her injuries five days later.

The SIU says constables Craig McMurtrie and Rodney Donald Grubb are each charged with criminal negligence causing death, dangerous driving causing death, and conduct likely to constitute mischief causing actual danger to life.

The officers are to appear in Brantford court on March 23.

The SIU investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
