The Page County Sheriff’s Office says charges are pending following an injury accident that took place Monday evening, about 1.5-miles east of Shenandoah. Sheriff Lyle Palmer reports, the accident occurred at around 5:40-p.m. on Highway 2m near the intersection with C Avenue.

An accident investigation determined a 2016 Jeep Cherokee driven by 28-year old Dustin Richard Comstock, of Shenandoah, was stopped in the westbound lane of Highway 2 waiting for eastbound traffic, to clear so he could turn south onto C Avenue.  20-year old Drew Alexandria Ann Esque, of New Market, was traveling westbound on Highway 2 east of the intersection in a 2001 Ford Taurus.

For unknown reasons, Esque didn’t see Comstock’s stopped SUV. Her car hit the rear end of the Jeep, causing the SUV to move west in the westbound lane before it came to rest.  Esque’s car continued west in the eastbound lane before finally coming to rest in a ditch southwest of the intersection.

Both Comstock and Esque were transported to Shenandoah Memorial Hospital for treatment of unknown injuries. Citations are pending against Esquel. The Page County Sheriff’s Office was assisted by Shenandoah Ambulance Service and Shenandoah Fire Department.
