Daniela Martinez was 9 years old when she was last seen on November 1, 2013, in Los Angeles. She was abducted with her three siblings — Francisco, Michelle, and Theresa — by their non-custodial mother, an event authorities have classified as a family abduction. The family believes the mother may have taken the children to Mexico, but nothing has been confirmed since they disappeared.

Daniela was born July 20, 2004. She is described as a Hispanic female with black hair and brown eyes, about 4 feet tall at the time of the disappearance. The Los Angeles County Sheriff’s Office is investigating and continues to seek information.

If anyone knew Daniela, her siblings, where the family spent time, or has information about travel to Mexico around November 2013, please share what is known with investigators.
