A man killed in a head-on crash in Liberty Township Saturday has now been identified. The Butler County Sheriff’s Office says 34-year-old Joshua Back of Fairfield Township was driving southbound on Princeton-Glendale Road, State Route 747, when he collided with a northbound pickup truck. The truck was preparing to take the westbound ramp to State Route 129. Back had to be freed from the wreckage and was taken to UC West Chester, where he later died from his injuries. Investigators say alcohol is suspected to be a factor in the crash, and that Back was driving erratically prior to the collision.
