State and federal officials investigating the explosion at the West Fertilizer Company say the cause is still “undetermined”.

But at an afternoon press conference they said they had ruled out a number of causes including  a fire at the plant, spontaneous ignition and one of two electrical systems . 

ATF Special Agent Robert Champion identified three other potential causes still being investigated: a 120 volt electrical system; a golf cart ; or an intentionally set fire.

Authorities say this is still considered a criminal investigation
