Homicide Capt. James Clark says 49-year-old Ronald Parncutt is charged with murder. A woman who answered the door at his home Monday said his family did not wish to comment.
Police say Parncutt shot 27-year-old Christopher Donaghy once in the back. Donaghy is the son of a Philadelphia police officer.
Clark says the loaded gun was left on a table by another guest, an off-duty Plymouth Township police officer.
"It's a total tragedy that something like this would happen during a festive time at of the Super Bowl and it's just something that should have never happen," Captain James Clark of the Philadelphia Police said.
The 29-year-old officer, a two and a half year veteran of Plymouth Township, who has not been identified has been placed on adminstrative leave pending the outcome of the investigations.
