"The police officer tried to initiate a traffic safety stop, and within seconds after initiating that safety stop, there was a collision," said Boland.

Late Saturday afternoon, police said there were four people in the Honda Accord: the 17-year-old female driver, two male youths, and the 19-year-old womanfrom St. John's who was killed.

CBC News has learned she had a one-month-old baby girl.

Boland said the SIRT investigators have been called as they are in all cases where an RNC officer is present at an incident resulting in serious injury or death.

Investigators were expected to be in St. John's on Saturday.

Boland said he couldn't share why the officer, who is still on active duty, initiated the traffic stop. However, he stressed that he did not believe the officer committed any wrongdoing.

Weather conditions at the time will also be assessed in the investigation, he said.
