LAWRENCE, Kan. (AP) _ It's been 20 years, but Harold and Alberta Leach have not given up the search for their missing son.
Seventeen-year-old Randy Leach disappeared from a party at a farm home seven mile east of Linwood in April 1988.
Since then, the Leaches have tracked down hundreds of tips and clues, searched many areas around the house _ and still have no concrete idea of what happened to their son.
Witnesses say Randy drank too much at the party, but no one saw him leave the party.
Authorities believe someone knows what happened to Randy, but for some reason has been afraid to come forward.
The Leavenworth County sheriff's office and the Kansas Bureau of Investigation reinvestigated the case in 2003. About two or three leads still come in every year, but the case remains an open missing persons case.
