Investigators work at the train derailment site July 9, 2013 in Lac-megantic, Quebec, Canada. The death toll from the massive explosion caused by a runaway oil tanker train that derailed July 6 and flattened part of the small Canadian town has risen to 13, a coroner said Monday, and dozens more remain missing. Confirmation of eight further deaths in Lac-Megantic, in Quebec province, came as environmental officials warned that around 100,000 liters of oil spilled in the disaster was headed for the Saint Lawrence seaway.
