Crownover was last seen in Hamilton County, Tennessee on November 26, 1987. She was living with Joseph Duenas in the 6400 block of Pythian Drive at the time. Duenas said he and Crownover went to bed at 11:00 p.m., and when he woke up the next morning she was gone. She left a note saying she would call, but she has never been heard from again. Crownover left behind all her clothes and most of her other personal belongings, including her vehicle, at Duenas's house. She apparently took $200 with her, however. Duenas reported her missing on December 4. Her case remains unsolved.
