Robert Leonard Longson, known to family as Bob or Bobby, vanished from Las Vegas in the spring of 1998. He was 52 at the time, about 5 feet 10 inches and 155–160 pounds, with blond hair, blue eyes and eyeglasses. The last confirmed sighting was by his sister in May 1998; after that meeting his contact with family stopped and his whereabouts became unknown.

The Las Vegas Metropolitan Police Department opened an investigation, but the trail grew cold and years passed with no significant leads. Partial human remains were later discovered; while the timing and location of that find are not widely publicized, it shifted the case toward identifying an unidentified decedent. Robert’s daughter and sister provided familial DNA samples that were uploaded to national databases as part of the effort.

What can readers who knew Bob in Las Vegas in 1998 add that might help resolve where he went or when?
