A man and a woman died early Friday morning when heavy flames and smoke tore through their home in Duquesne.

The Allegheny County Medical Examiner identified the man as Krystian Andrew McDonnell, 23. The woman’s name has not yet been released.

Firefighters responding to a call in the 1100 block of Karl Avenue encountered intense flames shooting from the rear of the 2½-story brick building, according to emergency dispatchers.

Duquesne City fire chief Frank Cobb said firefighters tried to enter the building but were turned away by the flames and had to douse them before re-entering.

One of the victims was found at the top of stairwell and the second victim was located in a second-floor bedroom, Cobb said.

The fire was brought under control shortly after 1 a.m.

The Allegheny County Fire Marshal is investigating the cause of the fire.
