***UPDATE*** According to The Charley Project and the Doe Network, this missing girl has been found safe.
13-year-old Marceline is from Sudan and was living with a guardian in Chicago, Illinois when she disappeared. Her guardian reported her missing on December 25, 2000.
Authorities believe that she probably left of her own accord and isn't in danger. Marceline was reported missing five times before her December 2000 disappearance and has one prior arrest. Her visa has expired and she may be hiding to avoid deportation. Her case remains unsolved.
Marceline was last seen wearing a black puffy coat and red boots. She may go under the name "Gloria."
