A Dillsburg woman was killed in a one-vehicle crash in Cumberland County on Wednesday afternoon, according to state police.

Amy Lefchak, 45, was driving west on West Lisburn Road in Monroe Township when she failed to negotiate a right curve at the crest of a hill and lost control, said police. Her vehicle went into the eastbound lane of traffic before hitting a dirt embankment.

Lefchak was not wearing a seatbelt and was ejected from the vehicle.

Her 11-year-old son and 9-year-old daughter were passengers and were both wearing seatbelts, police said.

Both children suffered minor injuries and were taken by ambulance to Harrisburg Hospital as a precautionary measure, police said.
