Official: Cadaver dogs search in Kansas City blast

More than a dozen people were injured in the blast and resulting fire, which occurred just after 6 p.m. and completely destroyed JJ's restaurant. There were no reports of fatalities by Tuesday night, though authorities cautioned that could change because it was unclear how many people were inside at the time of the blast.

Kansas City Fire Chief Paul Berardi said cadaver dogs were called to the scene because of the size of the conflagration.

"I would always fear there are fatalities in a scene like this," Berardi said.

He said results of the search would take hours and that he expected his crews would be working the scene through the night.

City Manager Troy Schulte said it appeared an accident by a utility contractor had caused the blast, and a statement from utility Missouri Gas Energy late Tuesday reiterated that possibility, but Berardi and others cautioned that the cause was still being investigated.

"This investigation is ongoing," Berardi said. "We do have reports that there was an odor of gas earlier. But, again, this investigation needs to be concluded before we want to speculate on any of that."

Indeed, the smell of gas was very strong in the area hours after the blast. Berardi said the utility stopped the flow of gas about 8 p.m., and utility crews could be seen working in the area after the blast.

Witnesses noted street signs indicated utility work was being done in the area, and a JJ's employee said the restaurant was open but undergoing renovations.

Mayor Sly James was at the scene after the blast, praising the work of first responders.

"The first thing we need to be concerned about is the people that are injured," James said.

Police Sgt. Tony Sanders said the manager of JJ's restaurant was unable to account for three people, but it was unclear whether they were caught in the blaze or had left earlier.
