A volunteer searcher found missing 78-year-old Alabama resident Eleanor Alexander, who wandered away from home some time Friday night. Alexander suffers from dementia.

Authorities and several volunteers looked for Alexander over the weekend. They called off the search 9 p.m. Monday.

Gail Higgins and her search-and-rescue dog, a German Shepard, found Alexander at 11 a.m. today. Higgins found Alexander lying on the ground in a wooded area approximately 300 yards her home.

“She was not alert, but she was breathing and covered with bug bites,” Coweta County Sheriff’s Lt. Col James Yarbrough told UPI.com . “She was in bed clothes and her body temperature was below 80 degrees (Fahrenheit), and she had walked into a barbed-wire fence.”

Alexander was airlifted to Atlanta Medical Center. She is in critical condition.

"It's been three days. This lady's had no food, no water, no nothing," she told CBS, the Christian Post reports.
