OSWEGATCHIE, N.Y. (AP) -- Authorities say they're continuing the search for two Amish girls they say may have been abducted from a roadside stand in northern New York.

The St. Lawrence County Sheriff's Office says police patrols are out searching Thursday morning for 7-year-old Delila Miller and 12-year-old Fannie Miller.

Officials issued an Amber Alert for the two girls after they were apparently abducted around 7:30 p.m. Wednesday from the family's property in the rural town of Oswegatchie (ahs-wee-GAH'-chee), on the Canadian border 95 miles northeast of Syracuse.

Police say the girls went to wait on a customer at the family's 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. The vehicle has been identified as a white 4-door sedan. The vehicle is small with unknown plate number.

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

Anyone with any information on this abduction is asked to call the St. Lawrence County Sheriff's Office at 866-NYS-AMBER or dial 911 to provide information on a report or sighting.
