Carla Gabriela Caballero was 15 when she was last seen on October 15, 2000, in Fullerton, California. She was staying at a youth facility and authorities believe she climbed out of a cottage window and left voluntarily; the circumstances suggest she may have run away. She has not been heard from since.

Carla is described as a Hispanic female, 5 feet 2 inches tall, 170 pounds, with brown hair and brown eyes. At the time she disappeared she was wearing a dark gray sweatshirt, light gray sweatpants and white sneakers, and she has several tattoos on her arms, fingers and ankle. She may use the alias Monica Gonzalez.

Few details have emerged and the case remains unsolved. Anyone who knew Carla, her whereabouts after October 15, 2000, or who has information about the alias Monica Gonzalez is asked to come forward.
