Butler police say they are currently interviewing a suspect in the overnight shooting of a house on the 800 block of West Penn Street.

Three adults and two young children were in the two-story home but no one was hurt. The house was hit multiple times shortly after 11:15 p.m. Sunday.

Officers recovered five .40-caliber bullet casings from the outside the house near Mercer Street. All of the casings were in the same vicinity.

One slug was recovered on the floor in the house. Investigators said they believe the other slugs remain lodged and hidden in the walls.
