After a DNA test determined that Robert Cronin was the baby’s father, Cronin didn’t dispute the results, but insisted he never had sex with the child, a report said.
"I don't want to be known for a crime I didn't commit," he told Schenectady's WRGB-TV.
Cronin claimed the girl, with whom he was acquainted, became pregnant after coming in contact with clothing he had used while masturbating, Albany's WTEN-TV reported.
He told the station that he realizes his story may be difficult for some to understand but said the police who arrested him were just lacking scientific knowledge.
Police in Niskayuna, about 20 miles northwest of Albany, arrested and charged him with endangering the welfare of a child and felony predatory sexual assault against a child younger than 13.
Cronin, who has five children with his fiancée, was being held at Schenectady County Jail without bail, WRGB reported.
The girl gave birth recently and both she and the baby are being safely cared for, police said.
