Janesville Man Sentenced to 10 years in Prison for Child Pornography

According to a press release from the U.S. Attorneys Office - Western District of Wisconsin, 57 year old Janesville resident Mark Spengler was sentenced yesterday to 10 years in federal prison, followed by 15 years of supervised release for receipt of child pornography. Spengler must also pay $47 thousand in restitution. Spengler pleaded guilty to the charge on June 7, 2022.

On May 31, 2019, law enforcement officers executed a search warrant at Spengler’s residence. While examining Spengler’s computer equipment, a forensic analyst from the Federal Bureau of Investigation (FBI) found multiple videos showing prepubescent children engaged in sexually explicit conduct. Law enforcement officers also interviewed Spengler, who admitted that he used a file sharing program to search for and obtain child sexual assault material.

The charge against Spengler was the result of an investigation conducted by the FBI. Assistant U.S. Attorneys Elizabeth Altman and Julie Pfluger prosecuted this case.
