Authorities in Texas will release results of the joint investigation of the West, Texas fertilizer plant fire and explosions.
(NBC) A month's worth of investigating the West, Texas fertilizer plant explosions has eliminated several possible causes, but forced investigators to announce this on Thursday.
"At this time, State fire Marshall's Office, and the ATF are ruling the cause of this fire is undetermined," said Texas State Fire Marshall, Chris Connealy.
The invesitation will continue and concentrate on other possible causes that have not been eliminated.
Other areas to be focused on are electrical failure, bad battery on a golf cart, and more ominous option that raises the possibility of arson.
"Or an intentionally set fire..that has not been eliminated yet," said Robert Champion of ATF.
Investigators confirmed last week that ammonium nitrate stored at the plant detonated the explosions that left 15 dead and injured around 200 others.
The April 17th blast devastated a 37-block area created a crater 93-feet-wide and 10-feet-deep with one piece of evidence found two and half miles away.
