Circumstances of Disappearance

Deriggi was born four weeks premature at Northshore Medical Center. Despite a diagnosis of extreme hyperactivity, Lanny scored a 160 on an IQ test.

The Deriggi family lived in a 1950's-era house on the 400 block of Northwest 112th Terrace, across from an old dog-racing track, down the street from Barry University. Deriggi loved their backyard pool. His hangout was often the Barry athletic field. After he turned 13, his behavior worsened. Children began picking on him at school and he had started running away, for brief spells. Once, he was found in Fort Lauderdale, FL. Another time, his mother found him at the Barry field, alone.

The family had spent a couple days camping in the Florida Everglades, roasting hot dogs, hiking paths and fishing. They returned home late on July 26, at about 22.00, planning to drive to Disney World the next day.

On July 27, his mother was sleeping when Deriggi asked to go to Barry to play. When he did not return, his mother did not call the authorities right away, as he usually returned quickly. A day or two passed before she dialed Miami Shores Police.

Officers found some of his belongings in the hedges of a near-by house. They speculated he was meeeting somebody. Investigators interviewed neighborhood pals, to no avail.

In 1977, the Deriggi family moved to Georgia, leaving a letter, which left him instructions on how to reach them. They taped it inside the electric panel. No one is sure what happened to the letter. Deriggi has not been seen nor heard from since.
