Investigators have been unable to determine the cause of a fertilizer fire at an East Texas farm supply lot.
Officials said Monday there is no evidence or indication of a criminal or intentional act that caused last week's fire.
The fire broke out at the East Texas Ag Supply lot in Athens about 6 p.m. Thursday and flames reached about 60 feet.
No injuries were reported.
Athens is about 70 miles southeast of Dallas.
Athens Fire Chief John McQueary says "the only causes that could not be eliminated are related to an electrical failure."
Fertilizer fires have been of concern in Texas since an April 2013 fertilizer plant explosion killed 15, injured about 200 others and devastated the Central Texas town of West.
