JACKSON, Ky. -- On a snowy day in 1982, 6-year-old Kelly Junior Hollan vanished from Pine Tree Hollow in Knott County.
His mother, Judy Moore, told police that her son went out to play and she never saw him again.
Though Kelly Hollan has been missing for almost 28 years, an aggressive police investigation, inquiries by family members, and internet forums keep the case alive.
The latest tip came on Dec. 18, when Kelly's sister Margaret Campbell, who was only 10 when he disappeared on Feb. 12, 1982, told Letcher County Sheriff Danny Webb that her mother's sister, who recently died, might have left behind a letter with some information about the missing boy.
Campbell said Tuesday that her maternal aunt told her she was leaving a letter, "but we don't know if it's true."
Webb, a former Kentucky State Police lieutenant who worked in Knott County, was on the case from the beginning and investigated it for years.
"I've had a lot of cases," Webb said in an interview Wednesday. "In all my career, that's the case that bothers me the most. I followed every lead. It hasn't added up since day one."
Of the 13 cases listed for Kentucky with the National Center for Missing and Exploited Children, Kelly's is one of only two categorized as a "non-family abduction."
But Webb and Kentucky State Police Lt. Claude Little, who is now in charge of the investigation, say they aren't sure that the classification is valid.
"I don't know what happened to him," said Little.
