Firefighters continue to douse hot spots as the investigation gets underway into Evansville's latest warehouse fire. WNIN's John Gibson has more:
Evansville firefighters have made several return visits to the Garvin Street Warehouse since the blaze gutted the former Faultless Caster plant on Saturday.
They were called back to the scene Thursday to extinguish at least one more flare-up.
The Bureau of Alcohol, Tobacco, Firearms, and Explosives has sent a national response team to the site to help with the probe.
The ATF also responded to the Morton Avenue Warehouse Fire in October and the deadly N. Weinbach house explosion in August.
The Evansville Fire Department, the Indiana State Fire Marshal's Office, and the Evansville Police Department are also investigating Saturday's blaze.
There was no word on whether investigators believe the two warehouse fires were connected.
Officials did offer a $5,000 reward for help solving the Morton Avenue blaze.
The ATF says its teams consist of veteran special agents, forensic chemists, explosives enforcement officers, fire protection engineers, as well as accelerant and explosive detection canines.
