BIRD IN HAND, Pa. (WHTM) — Police in Lancaster County are now joined by the FBI in the search for a teen who did not return home from a church event Sunday afternoon.

East Lampeter Police say they called in the FBI because they wanted additional specialized resources to try and help find her.

The 18-year-old, Linda Stoltzfoos, was last seen Sunday on Stumptown Road in Upper Leacock Township.

Investigators are using dogs, horses, and drones to find her. They say it’s a missing person’s case but haven’t ruled out foul play.
