Tania Ochoa was 11 when she was last seen on July 12, 2010, in Grover Beach, California. She was with her two younger sisters, Briana, 9, and Mindy, 7, when all three disappeared. Tania was described as 4 feet 11 inches, about 130 pounds, with brown hair and brown eyes and light brown highlights.

Investigators say the children were allegedly taken by their non-custodial mother, Mireya Graciano. A felony kidnapping warrant for Graciano was issued two days after the children were reported missing. Authorities believe she may have taken the girls to Tijuana, Mexico. Mireya was described as Hispanic, 5 feet 2 inches, 180 pounds, with black hair, brown eyes, a chest tattoo reading M&M, and she may use the last name Bustos.

Multiple searches have not located Tania or her sisters and their whereabouts remain unknown. If anyone has information about Tania, her sisters, or Mireya Graciano, please share what is known with investigators.
