A North Huntingdon couple and their son were found dead in their home Thursday night in what police said was a double murder-suicide, but the motive and details remain unclear.
"I'm not going to say it's a mystery, but sometimes you just don't know," said Detective Sgt. Jeff Bouldin of the North Huntingdon police. "We may never know."
Officers on Thursday night discovered the bodies of Franklin Hutchison, 68, his wife Hazel, 67, and their son, William Hutchison, 46, in their small home on Guffey Road.
Police believe the killings occurred Tuesday morning.
Police received the call Thursday after the younger Hutchison's employer, a car dealership, called state police to say he hadn't shown up for work for several days. Troopers contacted North Huntingdon police, who went to the house about 9:20 p.m. and found the bodies.
Hazel Franklin was found in bed on the first floor and her son in a nearby hallway; Franklin's body was in the basement.
The Westmoreland County Coroner's Office has not released cause and manner of death and police said they are still investigating.
While detectives with the Westmoreland County District Attorney's Office described the case as a murder-suicide, they have not identified who did the shooting.
Sgt. Bouldin would not discuss the type of weapon used or any evidence found in the house.
His department and the detectives were awaiting autopsy results Friday, but nothing pointed to an explanation.
Sgt. Bouldin said police talked to Bruce Hutchison, 44, of White Oak, younger brother of William, but he was unable to shed any light on a motive.
Neighbors on busy Guffey Road, where the small houses are tightly packed together, said they heard no shots, nor had they heard arguing or a commotion before the shootings.
Police had been to the house before, but only to address complaints about Franklin Hutchison's dogs. They had not been there for any domestic disturbances, and interviews with neighbors yielded little insight about what went on in the house.
One neighbor, who was relatively knew to the neighborhood, said Friday morning that he'd only seen Franklin a few times and never saw Hazel or William.
The family, which had lived in the house since 1975, kept to themselves.
"Nobody really knows them," said Sgt. Bouldin.
Correction, April 20, 2013: An earlier version indicated the son had shot the parents. Authorities have not yet released information on who did the shooting.
