A Pennsylvania teen shot and killed his parents and younger brother before turning the gun on himself in a horrific triple murder-suicide.

Police found Michelle Hunt, 48, and Clifford Hunt Sr., 51, dead in their North Sewickley Township home Sunday night, reported KDKA.

Their two sons, Cody Hunt, aged 16, and Clifford Hunt Jr., aged 19, were found in severe condition and airlifted to a hospital in Pittsburgh, where they later died from their injuries.

Investigators believe Clifford Jr. shot his family members in the head before shooting himself, according to WPXI.

‘At this stage, it does look like the older son, Clifford Jr., may have been the last one alive,’ said Beaver County District Attorney Nate Bible.

Several weapons were removed from the scene, and authorities are still determining which weapons were involved and their targets, while trying to establish a timeline of the events.

Police arrived at the scene after Cody made a harrowing 911 call from inside the house, reported WTAE.

‘The entire family were passionate hunters, and whenever I spoke with them, the topic of hunting would inevitably come up. I was aware that they possessed a significant number of firearms at home,’ stated North Sewickley Township Police Chief Jeff Becze.

The devastated community remembered the family fondly and is working to rehome the dozens of farm animals they kept.

Michelle and 16-year-old Cody were active volunteers at the Air Heritage Aviation Museum, and the teen dreamt of becoming a pilot.

‘They both loved and had a vast knowledge of the aircraft and enjoyed sharing its history with people who toured it during air shows. Cody recently obtained his pilot’s license, and he and his mother were very proud of his achievement,’ the museum said.

‘Michelle was one of our most active volunteers and always showed up with a smile on her face and ready to work, whether she was packing the C-123 for an air show, helping setup and hosting an event, or giving a tour of the museum.’  

Riverside High School identified Cody as a junior and said he was a member of the National Honor Society and played saxophone in the school marching band.

‘Eager to serve his country, Cody planned to apply to the United States Air Force Academy. He also volunteered at the Air Heritage Museum in Chippewa, where he shared his love for aviation with visitors,’ the school said.

‘Cody’s classroom teachers and friends would say he was kind-hearted and always helped others. Everyone at Riverside will miss him dearly.’

Michelle’s friend Autumn Ashurst said the two bonded over their love of animals and had seen her just hours before her death.

‘Oh, she was over the moon about getting ducks. She had a whole spot set up for them, wanted me to bring them in, and said they were ready, and the geese and turkey were checking them out. She was very happy and very excited,’ Ashurst said. 

‘It kind of seems unbelievable that something like this could even happen in an area like ours, it’s so quiet it’s so relaxed and to hear of any loss in the community is horrible.

‘It’s not only one tragedy, but it’s four all at the same time, and I can’t imagine how many lives are ruined over this it’s insane.’
