Ken DeFoor said Clymer is charged with continuous sexual abuse of a young child. "It’s the past several years that we know of so far, but the investigation is still continuing," said DeFoor. DeFoor referred to the incident as a familial situation and said investigators were contacted by Child Protective Services after the child told her mother and school officials. Liberty fire officials said Clymer had been with department as a volunteer since 2002 and was suspended as soon as the accusations came to light.
