UPDATE: According to the Gilmer County Sheriff's Office, Earl "Tater" Townsend has been found and is safe. No other details are immediately available.
Townsend was found by a motorist on Tails Creek Road. He was taken to North Georgia Medical Center, where he was evaluated and reunited with his family, the sheriff's office said on its Facebook page.
It had been more than 48 hours since Townsend, 68, of Gilmer County was last seen.
A neighbor of Townsend's on Ridgeway Church Road saw Townsend walking near his house Sunday evening. Officials from Gilmer County, Cherokee County and the Georgia State Patrol searched the heavily-wooded area around his home.
Townsend has Alzheimer's and COPD, a pulmonary disease that makes it hard for him to breathe.
"With that being said, we've covered almost 6.5 square miles of land at this point," said Gilmer County Emergency Management Deputy Director Aaron Freeman on Tuesday night. "We've found nothing, no evidence found of him."
Freeman said Townsend's family told him he has trouble walking and has to stop to catch his breath after about a hundred feet. Townsend was wearing a blue t-shirt, black pants and black shoes.
The area being searched is rugged terrain, filled with brush and woods, making it hard for searchers.
Freeman said 80 people have been searching around the clock and will continue until Mr. Townsend is found. But he has his concerns because it has been more than 48 hours since he disappeared.
"I'm concerned about the elements, being exposed to the elements," Freeman said. "Can he withstand it? Has he endured it? Is he injured somewhere that we can't see?"
"As of right now, we'll search until Friday morning until there's no evidence he's out there," he added.
