The teenager who was killed in an ATV crash Monday night in Northumberland County has been identified. Family members say 16-year-old Olivia Laudenslager, of Pitman, was riding on an ATV with friends on her 16th birthday. Olivia died when the ATV she was riding on tried to turn on to Schwaben Creek Road and collided with a car. The driver of the ATV was flown by helicopter to Geisinger Medical Center near Danville. Crews were out repairing damages to road signs on Tuesday and family members of the teen laid flowers to pay their respects.
