The search is on for a woman from DeWitt who has been missing for more than a month. DeWitt police chief Gene Ellis says 50-year-old Rebecca Lee Miller has a medical condition, but he’s not disclosing just what that condition is. A case worker who routinely checks on Miller called cops to report she’s missing. Miller was last seen February 10th, but she was not reported missing until last Thursday, almost a month later. “People are concerned about her welfare,” Ellis says. Miller is five-foot-two, weighs about 175 pounds and has blonde hair and blue eyes. Ellis believes she may be driving a 1995 green Ford Escort.
