Man pleads guilty to molesting boys in Lomira

July 18, 2018

JUNEAU — A 20-year-old Illinois man pleaded guilty Thursday to sexually assaulting two young boys and taking suggestive photos of them.

Seth D. Oltmanns, who is currently in Dodge County Jail, is from Mount Morris, about 20 miles southwest of Rockford. He appeared in the courtroom of Dodge County Circuit Court Judge Steven Bauer.

Oltmanns pleaded guilty to repeated sexual assault of the same child and six counts of possession of child pornography by a person under the age of 18. Bauer accepted Oltmanns’ plea and dismissed but read into the record an additional charge of possession of child pornography.

According to the criminal complaint, Oltmanns was staying at a relative’s house in the town of Lomira in July and August 2016. Oltmanns watched two small boys in the home, 8 and 10. The two mothers of the boys contacted police with separate phone calls Aug. 22, 2016, and each reported that Oltmanns had sexually assaulted the boys.

The 8-year-old boy attended a forensic interview three days later, when he told officers about the alleged abuse. The boy said that Oltmanns sexually assaulted him several times including insisting that the boys take a bath with him on one occasion. The 10-year-old boy underwent a forensic interview on the same day and told a detective a similar story.

According to the complaint, one of the boys told police that Oltmanns had taken several suggestive photos of the boys and saved them in a secret file on his phone.

Oltmanns allowed police access to his phone, but denied having the photos on the phone or anywhere else. According to the complaint, he eventually admitted to having the photos and said he attempted to delete them but was unable to do so.

He also admitted to having a secret file where he hid the photos. After the photos were found, he allegedly admitted to touching one of the boys inappropriately. On the phone, there were 37 images of young males in states of undress. In addition, police found that Oltmanns had done internet searches for boys in underwear and homosexual boys ages 10 to 14.

A sentencing hearing is scheduled for Nov. 8.
