A teenaged oil company employee was killed last week in Tyler County, West Virginia when he was struck by a truck, then pinned between the truck and a sand silo, according to news sources.

Nineteen-year-old Hunger D. Osborn was acting as a spotter for a tractor-trailer that was backing up to off-load sand when the accident occurred Thursday morning at an oil well pad.

Tyler County Sheriff’s Lt. Shannon M. Huffman said in a press release that Osborn was treated at the scene by EMTs and then airlifted to Ruby Memorial Hospital in Morgantown, where he died of his injuries.

Osborn was employed by U.S. Well Services of Jane Lew, which said it was investigating the accident. OSHA is also investigating.

The incident happened at about 7 a.m. Thursday on the Hartley East Pad at 395 Ricky Run Road in Middlebourne, Huffman said.

OSHA’s investigation is ongoing, and the agency will release its findings within six month, according to Fortson
