Authorities are searching for a great-grandmother from Atlantic County who went missing with her great-granddaughter during a holiday car trip to North Carolina.

Hamilton Township police say 71-year-old Barbara Briely and 5-year-old La'Myra Briely left from Mays Landing on Saturday morning and were last seen around 5:30 p.m. Saturday at a gas station in Ruther Glen, Virginia, where Barbara Briely had stopped for directions.

Family members say Barbara Briely has no known medical issues and has often driven to North Carolina without incident to visit with relatives. They have repeatedly tried to reach her by cellphone since she went missing and are tracing the route they believe she was traveling.

Briely was driving a silver Toyota Rav 4 with New Jersey license plate C80-ELS.

Anyone who might have any information about the pair's disappearance is asked to call Detective Robison at 609-625-2700 ext.578.
