Cynthia Colleen Allegro, known as Cindy, was 31 when she disappeared from her Independence, Missouri home in the winter of 1982. She was last seen on February 12 near the 800 block of East Walnut Street. At that time she was described as a white female, brown hair, brown eyes, five feet seven inches and about 115 pounds, with pierced ears, an abdominal scar, a small tattoo of either a rose or a butterfly below her navel, and previously fractured both ankles.

Cynthia and her boyfriend had planned a weekend trip to St. Louis, but it is unknown whether either of them reached that destination. A few days after she was last seen, her rental car was found abandoned at Kansas City International Airport with a broken windshield; Cynthia was not at the scene. Investigators have treated the case as endangered and suspect foul play. The circumstances after she left home remain unclear and the case is cold.

If anyone knew Cynthia, lived near East Walnut Street in 1982, or has information about the rental car at the airport, please share what you remember.
