One body has been pulled from the rubble of yesterday's explosion in Kansas City that destroyed a restaurant, reports AP. The Kansas City Star says it is thought to be a 46-year-old female server at JJ's restaurant. Authorities think she is the only fatality, but they won't know for sure until the cleanup is finished. The investigation continues into how the blast occurred, with a gas leak still the leading theory. Six people remained hospitalized. (More Kansas City stories.)
