A fatality report into the death of Misty Chalifoux and her three daughters during a police chase in northern Alberta makes no recommendations.

The judge overseeing the inquiry said recommendations are unnecessary as the RCMP has since changed its policy governing vehicle chases.

On Jan. 20, 2006 Chalifoux was taking her daughters shopping in Slave Lake when her car was hit head-on by a stolen pick-up truck being chased by police.

The officer chasing the truck was following proper RCMP policy when he initiated the pursuit, concluded Judge G. William Paul.

"The officer employed all of the emergency equipment on his police vehicle including continuous siren during his efforts to close the distance," he wrote.

"When the operator of the stolen vehicle failed to stop and appeared to be fleeing in an attempt to evade apprehension Cst. (Jeff) Schneider properly notified the dispatch operator of his declaration of pursuit which would lead to the engagement of a pursuit coordinator."

"He backed off immediately upon the stolen vehicle exhibiting fish-tailing actions within 17 seconds of that declaration," said Paul.

At that point the truck swerved into the path of Chalifoux's vehicle.

Raymond Yellowknee, a chronic drunk driver, pleaded guilty to four counts of dangerous driving causing death.

He was designated a long-term offender and sentenced to 20 years in prison.

Yellowknee killed himself in August 2009 while at Edmonton Institution.

Chalifoux left behind a husband and two sons.
