Sixteen-year-old Mariana Pineda was last seen in Alpharetta, Georgia, on Wednesday, December 17, 2003. She is described as Hispanic, about five feet four inches tall, roughly 110 pounds, with long black hair and brown eyes. On the day she vanished she was reportedly wearing blue jeans and a pink sweater.

The disappearance was reported to the Fulton County Police Department and her case is recorded in missing persons databases, including NCMEC under number 978655. Beyond those basic identifiers, there is very little public information about where she was last seen, who she might have been with, or what the initial investigation turned up.

Anyone who remembers Mariana, knew where she spent time in December 2003, or has information about her last known movements is asked to come forward.
