WAUWATOSA, Wis. (AP) -- Investigators are continuing to comb through the rubble of a house that exploded in Wauwatosa, killing one person and injuring three neighbors.

The identity of the elderly woman found dead in the basement of the structure hours after the blast Saturday is still not being released.

Fire Chief Dean Redman puts the initial damage estimate at $700,000 and says at least ten to 20 buildings were damaged.

The chief has said that the damage is consistent with a buildup of natural gas.

He says investigators have determined that the house was equipped with an electric stove, natural gas water heater and a natural gas furnace.
