Joan Adler was 63 and visiting Niagara Falls, New York, with her husband when she vanished on May 15, 1994. At the time she was described as a white female, five feet two inches tall, about 115 pounds, with gray or partially gray hair and green eyes. The New York State Park Police and the New York State Police in Niagara handled the official investigation.

Public information about what happened that day is minimal. Records note only that she was a visitor with her husband and that few clues emerged; specific search efforts, leads, or persons of interest have not been widely publicized. The case has gone cold and remains one of New York’s unsolved missing person files.

Are there any visitors, local residents, or park workers from that period who remember Joan Adler or have information about her movements on May 15, 1994?
