SIOUX CITY | A Castana, Iowa, man was sentenced Thursday to two years in prison for having sex with a teenage girl against her will while she was babysitting.

Colby Mauch, 25, had pleaded guilty in Woodbury County District Court to one count of assault with the intent to commit sexual abuse, an aggravated misdemeanor.

In addition to the prison sentence, Senior Judge Mary Jane Sokolovske placed Mauch a 10-year special sentence in which he will be on parole after completing his prison sentence. If he were to violate terms of the special sentence, he could be sent to prison.

Sokolovske also ordered Mauch to register with the Iowa Sex Offenders Registry and pay a $625 fine and $250 civil penalty.

According to court documents, on Sept. 3, 2016, Mauch traveled to the then-17-year-old girl's Morningside home, where she was babysitting six children. While the children were in the back yard, Mauch grabbed the girl, started to kiss her and forcibly pulled her pants and underwear down and had sex with her.   

The girl told a friend what had happened, and the friend notified a school resource officer, who told the victim's mother.

Mauch later texted the victim's mother and apologized. During police questioning, Mauch admitted to initiating and having sex with the victim, but claimed the sexual activity was consensual.
