"This disaster has severely impacted the community of West, and we want to ensure that no stone goes unturned and that all the facts related to this incident are uncovered," said Department of Public Safety Director Steven McCraw. That sounds more like the latter scenario: that there are no substantial suspicions of criminal activity at the moment, but if there was anything there, officials would be loathe to miss it.
McLennan County Sheriff Parnell McNamara echoed that sentiment, saying residents "must have confidence that this incident has been looked at from every angle and professionally handled — they deserve nothing less."
Reports surfaced today that a paramedic in West, TX has been arrested for possessing an explosive device. We have no reason to believe at the moment that he had anything to do with the factory explosion (the lack of a media swarm on this story is evidence that the two are unrelated), but Sheriff McNamara is right: the people affected by the deadly explosion at West, TX deserve the closure that comes with understanding why this tragedy happened.
