BALDWIN— Fire officials say a fast-moving blaze has trapped and killed two men in a Pittsburgh-area home.

Allegheny County Fire Marshal Robert Full says he doesn’t know the cause of the fire that raced through a two-story wood frame house in Baldwin Borough, just south of Pittsburgh.

Full says firefighters were called to the house shortly before 9 p.m. Monday. After the fire was controlled, Full says two bodies were found on the first floor of the house.

Full says rescue workers were told that two elderly men lived in the home, and one used an oxygen tank.
