(Lomira) An Illinois man was sentenced to six years in prison Thursday for assaulting two minors in the summer of 2016. In July, Seth Oltmanns of Mount Morris pled guilty to three felony counts of First Degree Sexual Assault of a Child and six felony counts of Possession of Child Pornography. The incident occurred while Oltmanns was staying at a relative’s house in the Town of Lomira in July and August of 2016. Prosecutors say the 20-year-old took suggestive photos of two young boys he was watching and saved it to his phone. The mothers of the boys contacted the police and reported the abuse in late August. In October, the Dodge County Sheriff’s Office was able to make contact with Oltmanns at his Illinois home. He initially denied the claims but later admitted to taking the pictures and to touching one of the boys inappropriately. In addition to prison, Oltmanns was placed on extended supervision for 15 years.
