Margaret Yossa was an instructional aide at Mission Elementary School in Oceanside, California. She disappeared in February 1994 and was not found until September 13, 1994, when skeletal remains identified as hers were discovered in a field. Her death has never been solved and no one has been charged in connection with her murder.

Investigators noted similarities between Yossa’s disappearance and that of a former colleague, Mary Rico, who vanished in 1992: both women lived within a mile of each other and were last seen shopping at the same grocery store. No conclusive link between the two cases was ever established. The circumstances of Yossa’s death remain unclear and the investigation is still open.

If anyone remembers Margaret, her routines, or saw either woman at that grocery store in the months before their disappearances, please share what you know.
