14-year-old Ericka Williams was last seen on February 19 in Philadelphia's Frankford section in the area of Frankford and Castor.
Today, her mother, father and supporters handed out flyers hoping to find a clue to her whereabouts and get her back.
Her mother says Ericka is mentally ill and needs medications.
The family is not sure if she is just lost or with someone.
The search is being supported by the efforts of Melvin Figueroa whose own daughter Letoyia was murdered in 2005.
