At least 60 people are now believed to be either missing or dead after a runaway train carrying 72 tanker cars of crude oil exploded in a Quebec town on Saturday.
The police in Quebec say they've launched a criminal probe into the disaster which destroyed the center of Lac-Megantic east of Montreal.
The death toll still stands at 15. but officials say they've requested DNA samples from dozens of families whose loved-ones are missing.
Ed Burkhardt, the Chicago-based head of the railway company responsible for the train, is visiting the scene of the disaster.
He's called his company's safety record "reasonable", and told reporters a local firefighting team may have shut down the engine that controlled the train's brakes.
