Canadian authorities are looking into whether the train that derailed and crashed into Lac-Megantic, Quebec, was tampered with. Quebec police inspector Michel Forget told reporters on Tuesday that a criminal investigation has been opened in the fiery crash, which has so far left at least 15 dead and scores more missing. Investigators are examining the train's brakes to see if they had been disabled prior to the crash. Firefighters in the nearby town of Nantes had been called to quell a separate blaze and shut down the locomotive before the train derailed. Rail officials said they have begun an internal inquiry.
