SOUTH BUFFALO TOWNSHIP (KDKA) — The search for Kenneth Himes, 70, stopped around dusk Thursday in Armstrong County. However, before that, nearly 200 people spent hours hoping to find any clue at all pointing them to his whereabouts.

“Right now, we have no sign at all,” said South Buffalo Township Fire Chief Randall Brozenick.

There is no sign of Himes who has dementia and autism. Grid searches took place and other searchers rode horseback. Divers even searched for Himes in a pond after some search dogs got a scent there, but found nothing.

Kelly Caliguri and her daughter did what they could to help out.

“Immediately, her and I jumped into action, got our orange on and walked in the woods as soon as we could, checking cars, everything we possibly could,” said Caliguri, a neighbor.

Himes was last seen when he went to bed around 11:30 p.m. Tuesday. He was staying at his brother’s house for Christmas on Cadogan Slate Lick Road in South Buffalo Township. Relatives went to check on him Wednesday morning and he was gone.

“He’s been out there for a long time, so real concerned. He could be overcome by weather and everything else,” said Brozenick.

“One thing we do know, people with dementia tend not to go very far,” said Keith Conover, with Allegheny Mountain Rescue Group. “We’ve found people who have been out in the cold weather who survived for a long time. At this point, we’re still trying to find someone who’s alive and rescue.

Himes is 6-foot-2-inches tall, weighs around 140 pounds, has short, light brown and gray hair and blue eyes.

“It’s sad and we are praying for the best,” said Caliguri.

Crews will not continue searching for Himes on Friday. However, officials Pennsylvania State Police will continue to investigate and follow any new leads.

However, a pond behind the home where Himes was last seen has been the focus, and crews were staying there Thursday night until they finished pumping the water out. They initially thought the pond was shallow, but it turns out one spot is 20 feet deep, so they want to exhaust all options before ruling it out.

They are asking neighbors to keep a look out for Himes.
