Davenport was last seen leaving on her way to school on April 27, 1973. She lived at the Bermuda Palms motel (now a Motel 6) in the 700 block of east San Francisco Boulevard. She was a kindergarten student at Bahia Vista School. Davenport left home at 11:00 a.m. to walk to school. She never arrived. Her family didn't realize she was missing until evening, when she didn't come home from school. They reported her disappearance to police the next day.

Davenport lived with her grandparents and other relatives at the time of her disappearance; her parents were separated. Little evidence is available in her case. A witness reported seeing a dark green or black car following Davenport as she walked on Canal Street, but investigators have never been able to prove she was abducted and they have no suspects or persons of interest in her case. In 2009, police searched a crawl space at the motel where Davenport lived in response to longstanding rumors that her body was buried there. The search didn't uncover any evidence and Davenport's disappearance remains unsolved.
