SIDNEY — A Sidney man will spend the next 36 months in prison on one count of unlawful sexual conduct with a minor, a felony of the third-degree.

Robert J. Monnin, 31, of Sidney, appeared in Shelby County Common Pleas Court Thursday for sentencing. He had pleaded guilty to the count in May on a bill of information, waiving having the case presented to a grand jury.

According to the bill of information he “being 10 or more years older than the other person, did have sexual intercourse with a 14-year-old juvenile.”

During court Thursday Shelby County Prosecutor Tim Sell said Monnin engaged in sexual relations with the child at least seven times, if not more. He said considering her age, it is appropriate he get prison time.

Monnin’s lawyer, Jose Lopez, said Monnin cooperated with the authorities, and entered a guilty plea immediately, speaking to the amount of responsibility he took for his actions.

Judge James Stevenson said the pre-sentencing investigation said Monnin’s attitude concerning his actions were troubling. He noted Monnin said the victim was not harmed and it wouldn’t have been a crime if he and she were both older. Stevenson said he took responsibility criminally, but not really for his actions.

In addition to the 36 months, he will have to serve five years of probation upon his release and register as a tier II sexual offender. He was given five days credit on his sentence for time he spent in the county jail. Monnin will also have to pay a $500 fine in addition to court costs.
