Criminal Sexual Assault Definition in Chicago, Illinois
To understand what constitutes criminal sexual assault under Illinois law, it’s important to take a close look at the statute and understand the exact language that defines the offense. Under 720 ILCS 5/11-1.20, a person commits criminal sexual assault when they commit an act of sexual penetration and:
- They use force (or the threat of force)
- They know the victim is unable to understand the act or give consent
- They are a family member of the victim (and the victim is under 18 years old), OR
- They are 17 or older and are in a position of power or authority over the victim (like a teacher, coach, or supervisor) and the victim is between 13 and 17 years old
There are some important terms to understand from the statute itself: “sexual penetration,” the “force (or the threat of force),” and “lack of consent.” 720 ILCS 5/11-0.1 lays out the definitions for all three of these terms:
- Sexual penetration: Any slight contact or entry involving private parts, body parts, or objects, no matter how minimal.
- Force or the threat of force: Using violence, threats, or physical power (like intimidation, restraint, or size advantage) to make someone engage in sexual activity against their will.
- Lack of consent: A person cannot freely agree to sexual activity. Submission due to fear, force, or pressure does not equal consent.
If someone has committed a sexual offense with these combination of factors, they have committed criminal sexual assault under Illinois law.

Remain Silent After Your Arrest

Clearly request an attorney and refuse questioning until your lawyer is present to protect your rights.

Consenting can give prosecutors in Cook County additional evidence to support criminal sexual assault charges. Politely decline and wait for your attorney, who can advise you on whether compliance is legally required in your specific situation.
Avoid Contact with the Accuser
After being accused of rape or criminal sexual assault in Chicago, do not contact the alleged victim under any circumstances. Even messages intended to clarify misunderstandings can be used against you in Cook County court. Prosecutors may interpret communication as intimidation or admission of guilt. Let your attorney handle all interactions and avoid creating additional evidence that could strengthen the case against you.
Stay Off Social Media During Your Case

Prosecutors frequently review online activity for statements, photos, or messages that could be used as evidence. Even unrelated posts may be taken out of context.

Criminal Defense Strategies Against Sexual Assault Charges in Chicago, Illinois
Hiring a lawyer is the single most important thing you can do if you’re charged with criminal sexual assault in the Chicago area. They can build an effective defense to help mitigate the impact of your sexual assault charges on your life.
At Combs Waterkotte, we’ve handled hundreds of criminal sexual assault cases throughout Cook County. This experience has allowed us to build and use defense strategies to help clients achieve favorable outcomes in these cases. Here are the criminal defense strategies we have found to be most effective against Chicago sexual assault charges:
Consent as a Defense in Chicago Rape Cases
In many Chicago criminal sexual assault cases, the central issue is whether the encounter was consensual. A consent defense acknowledges that sexual activity occurred but disputes the claim that it was rape. In Cook County courts, this often involves analyzing prior communications, behavior before and after the encounter, and whether actions reasonably indicated mutual agreement rather than force or lack of consent.
Challenging Credibility of the Accuser
A key defense strategy against rape charges in Chicago is challenging the credibility of the accuser. Cook County prosecutors often rely heavily on testimony, so inconsistencies in statements, prior accusations, or conflicting evidence can be critical. Your attorney may examine timelines, prior communications, and behavior to expose contradictions and create reasonable doubt about the criminal sexual assault allegations presented in court.
Using Text Messages and Digital Evidence
Text messages, social media, and other digital communications can play a major role in defending rape charges in Chicago. In many cases, messages before or after the alleged incident may suggest consent, contradict accusations, or undermine credibility. Preserving and analyzing this evidence early is crucial, as it can significantly impact how prosecutors and juries interpret the circumstances surrounding the alleged sexual assault.
Presenting an Alibi Defense
An alibi defense is particularly effective when the accusations against you are false. This defense asserts that you were not present when the alleged rape occurred. In Chicago criminal sexual assault cases, this may involve surveillance footage, phone location data, receipts, or witness testimony. Cook County courts will closely evaluate whether the timeline makes the accusation possible. A strong alibi can completely undermine the prosecution’s case by showing that the alleged incident could not have involved you.
Identifying Motives for False Allegations
In some Chicago criminal sexual assault cases, the defense may explore whether there is a motive behind the accusation. If your case goes to trial, a Cook County jury may consider whether personal, social, or financial factors influenced the claim. Establishing a reason for a false allegation can introduce reasonable doubt in a criminal sexual assault prosecution.
Leveraging Witness Testimony and Context
Witnesses who observed interactions before or after the alleged incident can be valuable in Chicago criminal sexual assault cases. In Cook County, testimony from individuals present at a party, bar, or gathering may help establish context, including behavior that suggests consent. These accounts can challenge the prosecution’s narrative and provide alternative explanations for what occurred during the events in question.
