DALLAS - Authorities are trying to determine what sparked a house fire in Dallas that left three people dead.
Emergency officials say neighbors reported the blaze early Thursday.
The Dallas County medical examiner's office told The Associated Press that the victims were a man, a woman and a child. Names were not immediately released.
Dallas Fire-Rescue spokesman Jason Evans says the fire apparently got into a stairwell and quickly advanced to the second floor of the home in northeast Dallas.
