Donna used to work at the convenience store as a clerk in Jr. Food Store in Gulf Breeze, Florida. Police found no evidence of a struggle at the store. This is why police suspected that she must have been kidnapped and murdered. Police were able to solve her case only when the half- brother of the main culprit confessed. Mark Riebe’s half-brother, William Alex Wells who was already in jail turned out to be the informant. He confessed that he and Mark kidnapped Donnah, killed her and buried her in the family property. William Alex Wells also had charges for kidnapping, assault, and murders. At that time he was serving the charges in jail.  William Alex Wells (left), Mark Riebe (right) It was only after the confession that the police could get to Mark Riebe.
