Oswegatchie, N.Y. — Authorities have issued an Amber Alert for two Amish girls they say may have abducted from a roadside stand in Oswegatchie.

The St. Lawrence County Sheriff's Office is investigating the possible abduction of Delila Miller, around 6 years old, and Fannie Miller, around 12 years old. It happened just before 7:30 p.m. Wednesday.

The sheriff's office says the girls went to wait on a customer at the roadside stand. A witness saw a passenger in a vehicle put something into the back seat, and when the vehicle drove off the children were gone.

Both girls were wearing dark blue dresses with blue aprons and black bonnets.
