15-year-old Amanda Koetter left her foster home in Seeley's Bay more than a week ago, and police are now asking for the public to help find her.

On Christmas Eve, the teen -- who has hitchhiked in the past, Kingston police say -- disappeared somewhere on her journey towards Kingston on Highway 15. She hasn't got in touch with her family or her foster parents, and didn't turn up at her assumed destination in Parry Sound.

When last seen, Amanda was wearing blue jeans, a white shirt under a blue hoodie, camouflage/brown boots, and a white "bomber-style" jacket.

She's about 5'7" with shoulder-length light-brown hair, blond and red streaks and brown eyes.

Anyone with information should contact Kingston police at (613) 549-4660 extension 2288 or Crime Stoppers at (613) 542-TIPS (8477) or 1-800-222-8477.

Seeley's Bay is about two hours south of Ottawa, just north of Kingston and Gananoque.
