Linda Ann Miller was 18 when she left San Rafael, California, for Guadalajara, Mexico, and was last seen on July 1, 1973. She traveled with a male companion who may have been named Cary Kristal. The family received a letter postmarked from Guadalajara in early September 1972; that is the last confirmed contact.

Her family did not report her missing until 2001. Early speculation included an unconfirmed report that she might have died in a rooming house fire in Mexico City, while her stepfather thought she and Cary could have been detained in a Mexican jail. The case was later reopened, but no further leads have emerged.

If anyone knew Linda, Cary Kristal, their whereabouts in 1973, or remembers seeing them in Mexico, please share what you know.
