EDIT: "Fire officials fear that the number of casualties could rise as high as 60 to 70 dead, said Dr. George Smith, the emergency management system director of the city." http://www.cnn.com/2013/04/18/us/texas-explosion/index.html

Also, I really don't like sounding like a conspiracy theorist, but it's the 20th anniversary of the Waco siege. https://en.wikipedia.org/wiki/Waco_siege
