Andrew Memmelaar was 17 when he left Lehigh, Kansas, on October 25, 1975, bound for relatives in Jeffersonville, New York, and he never arrived. He was described as red-haired with blue eyes, about 5 feet 11 inches to 6 feet 1 inch tall and roughly 150 pounds. Distinctive marks listed in the file include a one-inch scar on his lower left arm, a scar near his right armpit from a removed cyst, and a right-side collarbone that had healed poorly after a prior break.

The Sullivan County Sheriff’s Office in New York is the investigating agency and has kept the case open. Few details exist about his travel plans, mode of transport, or route, and those gaps have complicated the search. Multiple missing-person organizations have documented the case in hopes of generating leads. Any information from someone who knew Andrew, saw him during that trip, or remembers his planned route could be crucial. Would anyone who knew Andrew or his travel plans in 1975 step forward with what they remember?
