BUTLER, Pa. (AP/KDKA) – Authorities say a child was killed when a fast-moving fire roared through a western Pennsylvania home. The child’s two siblings and their father were injured in the blaze in Butler, which broke out around noon Thursday.

The child who died was found on the second floor of the home on Knox Avenue.

The children’s mother was at work when the two-alarm fire occurred, and no one else was in the home at the time. The cause of the fire remains under investigation.

Police say the father had smoke inhalation and the two siblings had smoke inhalation and burns. All three were taken to the hospital.
