Rhiannon Moon Malone was 15 when she was last seen on January 29, 2007, in Santa Rosa, California. She and her older brother, Connor Malone, had been staying at a shelter for teens and left that day supposedly to go to school, but neither sibling arrived and both have been missing since.

Authorities later found neither Rhiannon nor her brother was enrolled in a local school, and shelter staff believe false names may have been used. Rhiannon was described as 5 feet 3 inches, about 120 pounds, with brown hair. The disappearance has been treated as suspicious; there have been no major leads or confirmed sightings in the years since and the case remains open.

If anyone knew Rhiannon, where she stayed, who she associated with, or saw her after January 29, 2007, please come forward with information that could help locate her and her brother.
