APOPKA, Fla. (AP) — An Apopka teenager has gone missing while on vacation with her family in Washington.

Media outlets report that 14-year-old Katelynn Barlow was with her aunt and uncle, who have primary custody of her, when she disappeared around 9 p.m. Sunday.

The family was on vacation to Big Lake, Washington when Barlow walked out of her family's cabin and into 50-degree weather to use the bathroom. She was wearing pajamas and no shoes.

No one has seen her since.

Barlow's cellphone was found off the side of Interstate 5, about 30 miles away from where the family had been staying. Barlow's stepfather, Kevin O'Connor, says the teen is usually never without her cellphone.

The FBI is assisting in the investigation and sharing pictures Barlow hoping that someone recognizes her.
