Pennsylvania woman shot while answering knock at door

Police found the 60-year-old woman suffering from multiple gunshot wounds when they responded shortly before 4:30 a.m. to the home.

The woman was taken to a Pittsburgh hospital in critical condition and is expected to survive, police said.

Investigators said there was a knock at the woman's door, and as she approached, she was struck by shots fired through it.

Another person who was inside the home with the woman returned gunfire, but there have not been any reports of other injuries, according to police.

Police said they do not believe the woman was the intended target.

"There has apparently been an ongoing feud between two of the families in that area. It's quite possible that someone inside the house may have returned fire," Allegheny County Police Lt. Andrew Schurman said.
