EWING, N.J. (AP) — A gas leak and subsequent explosion destroyed at least 10 houses and damaged dozens of others at a suburban town house development Tuesday, killing a woman and injuring seven workers, authorities said. The body was not discovered until late in the day, on a car near the site of the explosion, after authorities had thought the neighborhood had escaped the blast without any deaths. Lt. Ron Lunetta said officials were not able to identify the victim and will await an autopsy for positive ID and cause of death.
