Two people were injured following a head-on vehicle collision in Cumberland County early this afternoon. Troopers say a 2016 Ford Focus driven by 27-year-old Chelsea Tyree of Crossville crossed over the center line on Highway 127 North and struck an oncoming 1997 Dodge Ram 1500 driven by 65-year-old Roger Brewer of Crossville. Brewer was transported by a citizen to Cumberland Medical Center for treatment while Tyree sustained minor injuries.
