CORNVILLE — A 21-year-old man was killed Friday night after a single-vehicle crash on West Ridge Road.

The driver, Joseph T. Faucher-Kuhlman, of Cornville, was pronounced dead at the scene, according to a statement from the Somerset County Sheriff’s Office. There were no passengers.

Faucher-Kuhlman was driving north on West Ridge Road in a black 2010 Cheverolet truck, Det. Lt. Carl Gottardi said in the written release. At approximately 11:10 p.m., the truck left the roadway, then struck a telephone pole and a small utility trailer that was parked in a private driveway.

Gottardi said the truck flipped over and landed on its roof. The driver, who was not wearing a seatbelt, was ejected and “subsequently pinned underneath the truck.”

The exact cause of the accident is still under investigation, Gottardi said.
