Rosario Moran was 17 when she was last seen in Concord, California, on January 6, 2003. She had recently arrived in the United States with her fiancé and was observed leaving her home with an unidentified Hispanic man who got into a dark-colored sedan.

Her fiancé said she had family and friends in Las Vegas, Nevada, so investigators have considered the possibility she traveled there. Her whereabouts remain unknown and the case is unsolved.

Anyone with information about Rosario’s movements around January 6, 2003, is asked to come forward.
