Summary based on the NamUs case record (MP7554) and 4 other sources
Leonard James Collins, a 31-year-old truck driver, was last seen on July 31, 1987, in West Palm Beach, Florida. Collins, who was also known by the nickname "Lenny," had told his estranged wife that he had secured a job as a long-haul trucker with routes to Texas and Tennessee. He was supposed to meet another trucker regarding this job, but details about the other person or the trucking company remain unknown. This meeting was the last time anyone heard from Collins, and he has not been seen since.

At the time of his disappearance, Collins was wearing a black t-shirt, blue jeans, and navy blue sneakers. He had a distinct 12-inch scar on his left forearm from a severe infection, and he sometimes sported a mustache or a full beard. He was a Caucasian male, standing about 5'10" tall and weighing 165 pounds. Despite the passage of time, no substantial leads have surfaced, and his disappearance remains a mystery.

Efforts to locate Collins have been ongoing for decades, but there has been little progress. The Palm Beach County Sheriff's Office continues to list him as a missing person. His case is still unsolved, with few details or clues available to explain his disappearance.
