It's been 18 days since 62-year-old Robert "Bob" Boone was last seen.
The search continues for the Camp Washington man who reportedly suffers from short-term memory loss and is without his medication.
FOX19 spoke with Boone's son, Bob Boone, Jr. on Saturday. He said he is thankful for the friends, family and neighbors who have continued to search for his father.
"We're doing everything we can here for him. The more eyes we can get on it, the better it will be," Boone, Jr. said. He said his father is fighting cancer for the second time and believes his short-term memory loss could leave him unable to remember how to contact family.
Boone was last seen on Tuesday, May 13 leaving his Burlington Place residence on foot.
Authorities say Boone is 5-foot-4 and weighs approximately 130 pounds. He has gray hair and blue eyes.
Anyone with information on Boone's whereabouts is asked to contact the District Five Investigative Unit at 513-569-8500.
