Lac-Megantic, Quebec, Canada train explosion

Quebec Provincial Police

Lac-Megantic's devastated downtown remained dangerous for days after the crash as responders put out fires and struggled to keep the remaining oil tankers cool so they wouldn't explode. The hazardous conditions delayed the search for people missing -- and now for bodies. 24 people are confirmed dead and 30 more are missing.
