SHALER — A father killed his wife and two children, one an infant, before turning the gun on himself inside the family’s rented home in the Pittsburgh suburb of Shaler, police said.

The unidentified man shot his wife and two daughters once each in the head late Sunday night, according to Shaler Township Police Chief Jeff Gally.

The body of one girl, about 8 years old, was found in a hallway of the home and bodies of the mother and an infant daughter were found on a bed. The father’s body was found on the bedroom floor.

“It’s a rented home and as far as we can tell they just moved in here three or four weeks ago,” Gally said.

Police described the neighborhood as quiet and largely crime-free. The home where the shooting occurred is one of about 10 homes on a dead-end street.

Investigators recovered a .357-caliber handgun from the house. No motive has been determined, police said.

“We have no indication as to what caused this tragedy,” Gally said.
