Predatory Criminal Sexual Assault Charges in Illinois: All You Need to Know!

Predatory criminal sexual assault charges in Illinois are an incredibly serious criminal offense and are charged as the most serious type of felony outside of first-degree murder. On top of significant criminal consequences, these offenses carry life-altering social, personal, and professional reputational consequences. Understanding these charges and their penalties is crucial if you or someone you know is being charged with predatory criminal sexual assault.

Legal Definition of Predatory Criminal Sexual Assault in Illinois

This offense in Illinois is called predatory sexual assault of a child. It occurs when someone who is 17 or older has any amount of sexual contact between a sex organ or anus of an individual and the body parts of another individual for sexual gratification, or commits sexual penetration, and the alleged victim of the offense is younger than 13 years old.

The offense is also charged if the victim is under 13 and the alleged offender does any of the following:

1. Commits the offense armed with a firearm
2. Discharges a firearm possession during the offense
3. Causes serious bodily injury to the victim that leads to permanent disability or is life-threatening
4. Delivers a controlled substance to the victim using threat or deception, or without the victim’s consent, and the controlled substance is not for medical purposes

Even minimal sexual contact can result in this offense being charged. It is a Class X felony.

Penalties of Predatory Criminal Sexual Assault of a Child

A Class X felony for this offense results in between six years and 60 years of imprisonment. A Class X felony is different from many other felony charges because it does not allow the offender to secure probation or conditional discharge in place of prison time. There are other penalties, including:

• Required registration as a sexual predator for the rest of the offender’s natural life
• A fine of between $75 and $25,000 for individual offenders
• While serving the imprisonment sentence, a maximum of 5 days of credit for every month of a sentence

Penalties can be more severe when the aggravating circumstances listed in the offense apply. These increased penalties apply when the offender was 18 years or older:

• An additional 15 years of imprisonment when the offense is committed armed with a firearm.
• An additional 20 years when a firearm was discharged.
• A term of 50 years to natural life imprisonment when the offense caused serious bodily injury.
• A term of 50 to 60 years of imprisonment when the offense was committed with a controlled substance.
• A term of natural life when the offense was committed against two or more persons, whether the offenses were related or unrelated.

When someone is convicted of a repeat offense under predatory criminal sexual assault, they are sentenced to a natural life term.

Potential Defenses to This Offense

The right defense for a case depends on the specifics of the prosecution’s case, the arrest, the accusations made, and many other factors. Some potential defenses to predatory criminal sexual assault of a child may include:

• A mistaken identity theft by the alleged victim or by unreliable eyewitnesses
• False accusations, which are more common when there are ongoing custody disputes or other serious family disagreements
• Insufficient evidence to meet the prosecution’s burden of proof
• Violations of constitutional rights like illegal search and seizures
• Issues with the interview of a child pornography, like leading questions or pressure from interviewers

Factors like an alibi, suppressing evidence due to rights violations, forensic tests, the timing of the offense disclosure, and other specifics about the offense can help build a defense to disprove the case brought by the prosecution. A skilled attorney is crucial to help you create a better defense against these very serious sexual assault charges.

FAQs

What Evidence Is Needed to Charge Someone with Sexual Assault in Illinois?

To charge someone with sexual assault in Illinois, evidence might include testimony of the alleged victim, witness testimony, forensic evidence, photos of injuries, and communication between parties.
