Investigators have begun the difficult and painstaking task of sifting through the charred debris of a structure brought down by an explosion, then destroyed by flames.
They're looking for enough evidence to determine what happened to the home in the 3900 block of Hogarth Avenue in Flint on Monday night.
"The explosion, did it come from basement, which lets us know as a fuel to sit low. If the house has a basement, if it was from upstairs, a fuel that rolls. People like with heaters and stuff like that, so now you get the natural gas. You got to take all those type of different things under consideration," said Flint Fire Chief Raymond Barton. The investigators will use several tools to try to find out what, if any, fuels were used, such as a sniffer or cadaver dog.
"They'll pick up the smell of accelerants or different things like that. That's going on," Barton said.
Investigators will often look back at the smoke from a scene for answers.
