Robin A. Heyler was 47 when she disappeared in the summer of 2008. The last confirmed contact was a phone call on August 7, 2008. She is believed to have been in Arizona at the time, with possible sightings at bus stations in Phoenix or Casa Grande, though her destination and intentions are unknown.

Her case was filed with the Indio Police Department in California as case number 2008I-1920, and the National Missing and Unidentified Persons System lists her under MP141760. Robin is described as a white female, white hair, hazel eyes, 5 feet tall and about 120 pounds. There is no clear information about clothing or belongings she may have had.

The circumstances of her disappearance remain unresolved and the investigation is open. Anyone who saw Robin around August 7, 2008, or who has information about her movements in Arizona or Indio, is asked to come forward.
