Three more people injured in a West Virginia house fire died Tuesday at West Penn Hospital's burn unit, authorities said.
The Allegheny County medical examiner's office said Alan Chamberlain, 29, died at 10:30 p.m., about eight hours after his daughter Brianna Chamberlain, 2. Her half-sister, Catherine Bolgar, 11, also died there at 5:50 p.m.
Brianna's twin sister and another 4-year-old sister died at a hospital in Elkins, W.Va., after the fire, Elkins fire Chief Tom Meader said.
The mother of the four children and an uncle remain at the burn unit in Bloomfield, where they and the three others were flown. Their conditions were not immediately available this morning.
The fire started shortly after 4 a.m. Monday at a single, two-story house in the city about 160 miles south of Pittsburgh. All seven family members were trapped inside, Chief Meader said.
Investigators from the West Virginia fire marshal's office and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives finished their examination of the scene Tuesday night. The fire's cause has not yet been determined, but is believed to have started on the porch and moved into the house, the chief said.
