NEW CASTLE — A Western Pennsylvania couple has been shot in their home, where police say officers were also forced to shoot a pit bull to gain entry.

New Castle police did not immediately release details of the shooting, which occurred about 3 a.m. today, except to confirm a man and woman who lived together were wounded and taken to an unspecified hospital.

A man who says he also lived in the home and is the female victim’s brother, tells reporters he wasn’t home at the time but was called by a child who also lives there who told police the shooting stemmed from a possible robbery.

Police say they planned to release additional information later today.

Reports that a third person may have been wounded could not be immediately confirmed.
