It was one year ago that a young Highland Park man disappeared in Costa Rica.

David Gimelfarb's parents lead a rally urging the US embassy and state department to become more active in the search. He vanished while hiking.

Luda and Roma Gimelfarb say there have been sightings in Costa Rica of a man resembling their son. They say they wonder if he was attacked or fell and may have amnesia.
