Powerful storms bring down trees, killing one teenager and injuring three others who were camping in the Allegheny National Forest near Sheffield, PA on Tuesday.


A group of about 25 kids and counselors with the"Pine Valley Bible Camp" were just waking up near the Minister Creek Campgrounds when the storms hit around 5:30am.


"In a 15 year career, it's nothing that I've experienced before. We had a pretty extreme weather event," said Rich Hatfield, the Bradford district ranger with the Allegheny National Forest. "There was lightening and high winds. We believe the winds brought trees down, and there were a number of trees down that fell into the camp site," he said.


The trees struck four kids, killing 15-year-old Alexis Turner of New Brighton, PA, which is in Beaver County.


According to the Warren County Coroner, Jerry Borden, Turner died of blunt force trauma to the head, neck, and torso. He believes she died instantly.


Three others were hurt, some with broken bones. One teen was airlifted to a hospital in Cleveland for treatment, but all are now in stable condition.


"It's a horrible tragedy. My heart goes out to the families involved," Hatfield said.


The campers come from many different states - Pennsylvania, Ohio, Virginia - they had hiked so deep into the woods, there was no cell signal. It was hours after the storm before the group could call for help.


Ten area fire departments responded, including Sheffield, Cherry Grove, and Clarendon.


One challenge for the crews was all of the down trees, splintered throughout the forest and along the roads.


"A lot of trees down, some still falling while they (EMS and fire crews) were still there. It was a pretty treacherous walk out carrying patients on backboards," said Jim Wagner, chief of the Cherry Grove Fire Department


The rest of the kids were checked out and fed at  the Cherry Grove Fire Department before returning to the Pine Valley Bible Camp in Ellwood City,


"I believe it was a rare tragedy. When people go out in the woods they need to pay attention to the weather and realize we might not have all the amenities big cities might. They are in the wilderness," Wagner said.
