Two parents and their two teen children were shot and killed in what Pennsylvania officials are saying is an apparent murder-suicide.

While the investigation is still in the preliminary stages, Beaver County District Attorney Nate Bible called the incident a triple murder-suicide.

The DA’s office and the North Sewickley Township Police confirmed to Fox News Digital that first responders were called to the Pittsburgh suburb of North Sewickley on Sunday at approximately 8:30 p.m. following reports of shots fired. Authorities later determined that the 911 call came from inside the home.

When officers arrived, they found the bodies of the parents, Clifford, 51, and Michelle Hunt, 48, and their two teen boys, 18-year-old Clifford Jr. and his 16-year-old brother, in grave condition. The teens, who each had gunshot wounds to their heads, were rushed to a Pittsburgh hospital, but died on Monday.

“Cody’s classroom teachers and friends would say he was kindhearted and always helped others. Everyone at Riverside will miss him dearly,” the statement said.

Elsewhere, the community pooled their efforts to honor the family by launching a GoFundMe aimed at covering the cost of four funerals.

“The Unthinkable has happened to all who knew and loved them and this tragedy has devastated the community,” a statement from Autumn Stang, the organizer of the GoFundMe, said. “This family of 4 from North Sewickley lost their lives in a tragedy that we are all still struggling to wrap our heads around.”

In a post following the shooting, the North Sewickley Police Department said it was “a contained incident” and that there was no threat to the public.
