Diana Kenner Powell was 32 when she vanished on July 16, 1979. She is described as a Black female, about five feet, six inches tall, around 130 pounds, with black hair and brown eyes. Records also list her as Diana Carol Kenner and Diana Carol Kinner.

There is uncertainty about her last known location: some official accounts place her last sighting in Kansas City, Kansas (Wyandotte County), while other records indicate Shawnee County, Kansas. No clothing description or clear circumstances from the day of her disappearance are available, and the case is listed as unknown. The Kansas City Police Department and the Kansas Bureau of Investigation are handling the open case, and her information has been entered into national missing persons databases.

If anyone knew Diana, saw her around July 16, 1979, or has information about where she might have been that summer, please share what is known with the investigating agencies.
