Police say they found evidence that a criminal act may have triggered the devastating runaway train crash that occurred in Lac-Megantic, Quebec over the weekend, reports CNN's Paula Newton.
At this point, 15 people are confirmed dead and 35 are still missing.
"They will not tell us exactly what they found or what leads them to this assumption, but what people have been focusing on... is that break system," says Newton. "Were they disabled? Did someone disable the brake system on purpose?"
