The New Year's Day apartment fire in Minneapolis claimed its first fatality Thursday as investigators and CenterPoint Energy debated whether natural gas was a potential cause of the explosion that sparked the fire.
Fire Chief John Fruetel said investigators were focusing on natural gas as a likely cause of the explosion that ignited the fire in the Cedar-Riverside neighborhood, although he said that weeks of investigation likely will be required to determine the cause.
However, a spokeswoman for CenterPoint Energy strongly discounted gas as the culprit.
"We had no natural gas in the area," said Rebecca Virden, who based her assertion on the utility's investigation and testing in the area. If the blast were due to were natural gas, Virden added, "the roof would come off, the walls would come out."
If a gas were involved, she said, "it could be a different type of gas."
Asked about CenterPoint's denial, Fruetel said, "I'm just basing it on what my investigators say."
He said that witness accounts of a natural gas smell and the type of explosion suggest gas was involved. He said that investigators early on ruled out an explosive device, despite the presence of Department of Homeland Security personnel on Wednesday.
At least 14 people were injured, six of them critically. The body of a fire victim was discovered Thursday afternoon as excavating equipment began knocking down walls of the gutted three-story building shared by a grocery and 10 apartments.
