Mangled metal and crushed vehicles are all that remains at the still-smoldering blast site of the fertilizer company, Thursday, April 18, 2013 in West Texas.  A massive explosion at the West Fertilizer Co. killed as many as 15 people and injured more than 160, officials said overnight.  The explosion that struck around 8 p.m. Wednesday, sent flames shooting into the night sky and rained burning embers and debris down on shocked and frightened residents.
