Allene Caldwell says her sister Debbie Bradshaw was walking her dog on Thursday when she went missing.

With no contact from Bradshaw, and reason to believe she might be in danger, Caldwell and her family are now searching on foot.

Family members are preparing flyers for their sister Debbie Bradshaw of Mayking, hoping to get her home. They say she may be danger because of her health.

“She has bad asthma, and she's been depressed about a year, and she's on a new medication and we were worried about that, maybe a reaction to it or something,” says Allene Caldwell, Debbie Bradshaw’s sister.

They say there is no reason to believe Bradshaw has left Letcher County.

“We don't really know where to start, other than around the area where she lives, and if we get any leads, we'll expand there,” says Caldwell.

“We have two different witnesses that have seen her in the Jenkins area, and we're pretty sure that she has been over there,” says Danny Webb, Letcher County Sheriff.

Family members handed out photos of Debbie at Jenkins Kids Day. One more woman said she spotted Debbie walking with her cocker spaniel in the area on Thursday, but hasn't seen her since.

“We just want to hear from her if she's alright. No matter what! I don't care, just call and say "Hey, I love you. I’m fine, Bye.'” says Caldwell.

The Letcher County Sheriff's Department has searched across the county with no signs of Bradshaw. Anyone with information should call police.

Saturday afternoon the Jenkins Fire Department used ladder trucks to look over the hills between Jenkins and Burdine for any clues to where Debbie Bradshaw might be.
