Landon Deriggi was 13 when he was last seen in Miami Shores, Florida, on July 27, 1973. That morning the family had just returned from a camping trip to the Everglades and Landon asked his mother for permission to go outside to play; he left the house on Northwest 112th Terrace and never returned. His disappearance was not reported immediately because he had a history of running away and had come back before.

Landon was born prematurely and had a deviated septum that affected his appearance. He was legally blind but refused to wear glasses, had been diagnosed with hyperactivity, and struggled socially at school where he was often bullied. Police found some of his belongings hidden in a nearby hedge, prompting suspicion he may have arranged to meet someone, but no solid leads followed. His family moved to Georgia in 1977 and left a note at the old home in case he returned; authorities suspect he may have died, but no remains have been identified.

Did anyone in Miami Shores or the Everglades area remember Landon or see signs of him after July 27, 1973?
