MIDDLETON, Wis.—Two people died when a house exploded and caught fire in southern Wisconsin, and authorities believe gunfire reported by neighbors happened when flames set off ammunition stored inside the home.

One person was found dead in the home’s ruins after it exploded around 11 p.m. Tuesday just outside the city of Middleton, and a second body was found Wednesday afternoon, said Middleton Fire Chief Aaron Harris.
