4 people were shot and killed at 643 Bottom Road in Allegheny Township.
According to police, a mother, father and adult son were at home when their daughter and another male intruder entered the house.
The father in the house reported to police the male and female intruder shot and killed his wife and son, and in self-defense, he shot and killed both intruders.
Many neighbors close by the incident say they can't remember anything like this ever happening before.
"You just don't expect it," said Ken Wills, who lives just down the street from crime scene. "It's a real peaceful neighborhood, never any problems, that's why we live here."
A news conference on the investigation is currently scheduled for Sunday 11:30am at the Ebensburg State Police barracks.
