A Madison County judge has ruled that a registered sex offender, Louis Arnold, is a Sexually Violent Person (SVP) and ordered him to be remanded to the custody of the Illinois Department of Human Services. Arnold was convicted in 2005 of criminal sexual assault and confessed to assaulting approximately 25 other victims, including a 12-year-old.

Why it matters

The Sexually Violent Persons Commitment Act allows the Illinois Attorney General's office to seek to commit offenders deemed a threat to public safety to the custody of the Department of Human Services, where they undergo regular reevaluations to determine if they continue to meet the criteria for commitment as a sexually violent person.

The details

According to Attorney General Raoul, Arnold was convicted in 2005 of luring and raping a woman in an alley while threatening her life with a knife. During his treatment, he confessed to assaulting approximately 25 other victims, with at least one victim as young as 12 years old. The judge's ruling means Arnold will be detained in the IDHS Treatment and Detention Facility.

  • In 2005, Arnold was convicted of criminal sexual assault and sentenced to eight years in prison.
  • On April 8, 2026, a Madison County judge found Arnold to be a Sexually Violent Person.
