Wednesday's explosion in Allentown involved an underground gas main that lacked shut-off valves. It took utility workers five hours of punching through ice, asphalt and concrete to seal the 12-inch main.
Lehigh County Coroner Scott Grim said four bodies were recovered - a 4-month-old boy, a 16-year-old girl, a 69-year-old woman and a 79-year-old man. Cadaver dogs found the fifth victim, a 74-year-old woman, in the rubble Thursday night.
In all, 47 homes were damaged, and eight appeared to be a total loss.
