No arrests have been made yet, Elder said, adding that investigators had eliminated accidental and natural causes for the incident.

More than 400 interviews have been conducted and more than $2 million was spent on the probe, which is still active and ongoing, Elder said.

Of the 15 who died in the April 17, 2013 fire and explosion, a dozen were first responders, Elder said. Many other people were injured and more than 500 homes destroyed.
