The driver's frantic attempt to escape the law happened early Sunday morning, according to investigators with Ontario's police watchdog, which has been called in to oversee the case.
The Special Investigations Unit says a Wellington County OPP officer tried to flag the vehicle down but it would not stop.
Once the officer caught up, the SIU says the vehicle had been abandoned after crashing into a 24-year-old woman. She was a pedestrian, who investigators say was gravely hurt and later pronounced dead at hospital.
The suspect had fled on foot, according to the SIU.
Sunday afternoon, Guelph Police issued a public plea for help finding the suspect, asking anyone who might have information to call investigators.
Police say the suspect allegedly stole the vehicle in the Eastview Road and Starwood Drive area in Guelph's east end.
No description of the suspect was available but police say given the severity of the crash, the person is likely injured.
