In a statement, the company called the blast “a tragic accident”.
Brice McCracken, an official from the Bureau of Alcohol, Tobacco, Firearms and Explosives, told reporters that authorities “are not any closer today to determining the origin and cause of this explosion”.
Davis had said earlier: “Can I say we’re going to rule out foul play? We can’t answer that. That might be days or weeks or months before we can do that.”
Authorities were slowly processing the blast scene one foot at a time, the sheriff said, calling in bomb technicians every time they felt there was a risk of danger.
DNA testing will be used to identify remains.
