Investigators Taking Another Look at Texas Fertilizer Plant Explosion

WEST, TX - APRIL 18: Search and rescue workers comb through what remains of a 50-unit apartment building the day after an explosion at the West Fertilizer Company destroyed the building April 18, 2013 in West, Texas. According to West Mayor Tommy Muska, around 14 people, including 10 first responders, were killed and more than 150 people were injured when the fertilizer company caught fire and exploded, leaving damaged buildings for blocks in every direction.

The explosion last month at a fertilizer plant in West, Texas, claimed the lives of fourteen people and resulted in some of the most goose-bump-inducing YouTube clips known to man. The cause remains unknown as investigators ruled out water, natural causes, anhydrous ammonium, and ammonium nitrate in a rail car as likely explanations, but today investigators took the search to the next level: A criminal probe has been launched alongside the news that Bryce Reed, a first-responder who was interviewed extensively by the media in the aftermath, was arrested for having possession of a "destructive device," identified as a pipe bomb, that may or may not be related to the investigation. (Update: Reed has been charged for possession of pipe bomb components., but there is still no solid link between him and the fertilizer plant explosion.)
