A Ridgeland business is offering a $10,000 reward for information leading to the safe return of a Simpson County woman who has been missing since July 2.

Diana Fuller, 47, was last seen walking from her friend’s home in Florence, Fuller’s sister, Denise McKnight, said.

McKnight’s employer, HealthOne, is offering the reward in hopes of developing some leads.

Fuller, who has a history of mental illness, left without her medicine, money or identification. McKnight said Fuller has left before without notice but has always contacted someone in her family. No one has heard from her since she disappeared.

Simpson County Sheriff Kenneth Lewis said his office conducted an intense six-day search for Fuller. It included the use of a helicopter and cadaver dogs.

“We’ve done a lot of things to try and find her and we’ve turned up nothing,” Lewis said.

Anyone with information on her whereabouts is asked to contact the sheriff’s office at (601) 847-2921 or info@simpsoncountysheriff .com.
