Canadian officials probe mystery behind runaway train that caused fatal fiery crash
While emergency responders in Quebec, Canada sift through the wreckage for bodies which may never be found -- due to the intensity of the blaze caused by a train derailment on Saturday -- officials are focusing on why the train came loose from its overnight parking spot.
Five people are confirmed dead in the incident, which occurred when a train hauling 72 tanker cars carrying 30,000 gallons of crude oil each rolled seven miles downhill from an overnight parking spot and slammed into buildings in the small town of Lac-Megantic.
