On March 22, 2025, the case was presented to the St. Clair County State’s Attorney’s Office, leading to the issuance of several charges against Tiemann, including four counts of predatory criminal sexual assault involving a victim under the age of 13, classified as Class X felonies, and two counts of aggravated criminal sexual abuse where the offender is five years or more older than the victim, classified as Class 2 felonies.
