The Sanford Police Department is asking for the public's help locating a missing 16-year-old girl.

According to a post on the department's Facebook page, Ellie Thompson was last seen leaving her home in Sanford on February 12th, at around 2:00 in the afternoon. She was wearing a fuzzy brown jacket, jeans, a purple hooded sweatshirt, and was carrying a bright orange backpack.
