Members of the community have held a candlelight vigil to remember six people killed in a suburban Pittsburgh house fire and to pray for critically injured sole survivor.
About 250 people raised lit candles into the air and sang "Amazing Grace" Sunday night outside the McKeesport house where a woman, her four young children and her disabled father-in-law died early Saturday.
The Allegheny County medical examiner's office said earlier Sunday that the victims died of acute smoke and fume inhalation. Medical Examiner Karl Williams said she believes they were unconscious by the time the flames reached them.
Relatives said the injured man and the woman initially managed to escape the fire but returned to try to save the others.
The cause of the fire remains under investigation.
