Summary based on the NamUs case record (MP5650) and 5 other sources
Gregory Robert Mitchell, a 16-year-old from Winter Haven, Florida, went missing on November 16, 1981. He was last seen with his friend, David Rees, as they left to unload a truck. Neither Gregory nor David has been seen since that day. Gregory's mother reported him missing a month later, on December 15, and David's stepfather reported his disappearance on December 26.

Gregory was last seen wearing a dark blue or black jacket, a gray and black t-shirt, jeans, and orange and white sneakers. He had a scar on his shin from a bicycle accident, and his hair was shoulder-length at the time. Foul play is suspected in their disappearances, and it is believed they might have traveled to North Florida, though no substantial evidence has surfaced. Despite the time that has passed, their case remains unsolved, and law enforcement continues to seek any information that might provide answers.
