WEST, Texas (AP) - Authorities have not ruled out criminal activity and are investigating two other possible causes in the explosion at a Texas fertilizer plant that killed 14 people.
Two officials familiar with the findings told The Associated Press Thursday that investigators haven't pinpointed the cause of the April 17 blast in West.
One state official who's seen a report on the probe says investigators are focused on a golf cart on the premises that had been recalled by its manufacturer, an electrical problem or possible criminal activity. A second law enforcement official briefed on the findings confirmed no definitive cause has been found.
Both officials spoke on condition of anonymity because briefings were ongoing and they did not want to speak publicly before a scheduled news conference by state and federal authorities.
