LAC-MEGANTIC, Quebec — Canadian authorities said they have opened a criminal investigation into the fiery wreck of a runaway oil train in this small town as the death toll climbed to 15, with dozens more bodies feared buried in the burned-out ruins.
Quebec police Inspector Michel Forget said Tuesday that investigators have "discovered elements" that have led to a criminal probe. He gave no details but ruled out terrorism and said police are more likely exploring the possibility of criminal negligence. Provincial police spokesman Sergeant Benoit Richard said no arrests have been made.
The death toll rose with the discovery of two more bodies Tuesday. About three dozen more people were missing. The bodies that have been recovered were burned so badly they have yet to be identified.
Investigators zeroed in on whether a fire on the train a few hours before the disaster set off a deadly chain of events that has raised questions about the safety of transporting oil in North America by rail instead of pipeline.
The unmanned Montreal, Maine & Atlantic Railway train broke loose early Saturday and sped downhill in the darkness nearly seven miles (11 kilometers) before jumping the tracks at 63 mph (101 kph) near the Maine border. All but one of the 73 cars were carrying oil. At least five exploded.
Rail dispatchers had no chance to warn anyone during the train's 18-minute journey because they didn't know it was happening themselves, Transportation Safety Board officials said Tuesday. Such warning systems are not in place on secondary rail lines, said TSB manager Ed Belkaloul.
The derailment and explosions destroyed about 30 buildings, including the Musi-Cafe, a popular bar that was filled at the time, and forced about a third of the town's 6,000 residents from their homes.
Resident Gilles Fluet saw the approaching train.
"It was moving at a hellish speed," he said. "No lights, no signals, nothing at all. There was no warning. It was a black blob that came out of nowhere."
