WAUWATOSA, Wis. (AP) -- Authorities say the body of a woman was found in the basement of a Wauwatosa home that was flatted Saturday in an explosion.

Wauwatosa Fire Chief Dean Redman says three neighbors were also injured in the blast, including one seriously enough to be treated at the hospital with non-life threatening injuries.

Redman says the woman in the home was likely in the kitchen when the explosion occurred.

Her identity has not been revealed, but a family member was on the scene.

The blast took place shortly after 11 o'clock and sent neighbors outside to see a plume of debris and fire shoot 75 feet into the air.

Debris was scattered as far as two blocks away.

Neighbor Brad Allen says his entire home shook as a result of the blast.

Redman says authorities are still investigating what caused the explosion that also severely damaged several other homes in the neighborhood.
