Two men are dead and two women were injured when their house in Kent, Wash. went up in flames early Friday.
Dispatchers received multiple frantic calls from inside the house and from neighbors, according to KOMO.
The house was fully engulfed in flames.
South King County Fire and Rescue Assistant Chief Gordie Olson says the fire was so intense firefighters couldn't enter, the station reported.
Crews later found the bodies of a 69-year-old man and a 19-year-old man, believed to be related.
One neighbor said he heard what sounded like an explosion before the fire.
