Investigators in New Albany were up early Wednesday sifting through the rubble after a house explosion Tuesday afternoon injured six people. It happened about 4 p.m. at Woodrow Avenue and Market Street. Six people were hurt in the blast -- including five people who were inside the home and one person outside. Were told that their injuries were not life-threatening. The house was heavily damaged by the blast and fire, and crews demolished it within hours because it was structurally unsafe. The demolition equipment was brought in late last night.
