Nodaway County Sheriff Darren White told the Huffington Post his department presented a "strong case" to prosecutors that then 17-year-old Matthew Barnett raped Coleman's daughter.
He said charges were dropped when Daisy Coleman declined to cooperate with prosecutors.
Melinda Coleman told CNN's Erin Burnett on Monday that White's claims are "absolutely not true," and said the police report from the incident proves it.
"The victims decided they no longer wanted to participate in the case," White told HuffPost. "They gave no deposition or statement and invoked their Fifth Amendment right not to incriminate themselves. The charges being dismissed had everything to do with the victims not wanting to assist in their case."
Prosecutor Robert Rice eventually dropped all charges against Barnett, who said the sex was consensual.
