Criminal Sentencing in Illinois: What to Expect at Your Hearing

A sentencing hearing is a separate court proceeding that takes place after a guilty verdict or a guilty plea. In Cook County, that hearing is typically scheduled at the Richard J. Daley Center or the George N. Leighton Criminal Court Building at 26th and California, depending on the nature of the case. The gap between conviction and sentencing can range from a few weeks to several months, and that window matters enormously for your defense.

During this period, the court may order a pre-sentence investigation — a formal process that gives the judge a fuller picture of who you are beyond the facts of the offense. Understanding each step in that window is the first key to navigating the process with confidence.

Illinois sentencing is governed primarily by the Illinois Unified Code of Corrections, found at 730 ILCS 5/, which sets out sentencing classes, ranges, and procedures. The law distinguishes between felonies (Class 4 through Class X and murder) and misdemeanors (Class A, B, and C). Each class carries a statutory sentencing range — a floor and a ceiling — that the judge must stay within unless specific enhancement provisions apply. Knowing your offense class is the foundation for understanding everything that follows.

The pre-sentence investigation report, commonly called the PSI, is one of the most important documents in the entire sentencing process. In felony cases, a PSI is generally required unless the defendant waives it or the court finds it unnecessary. In Cook County, PSI reports are prepared by the Cook County Adult Probation Department, whose officers are trained to gather comprehensive background information.

What goes into a PSI?

• Personal and family history, including childhood, education, and family relationships
• Employment and financial history
• Mental health and substance use history, including prior treatment
• Criminal history — arrests, convictions, prior sentences, and performance on any past supervision
• The circumstances of the current offense, often including the defendant's own account
• A summary of the victim's harm or loss
• Sometimes, a sentencing recommendation from the probation officer

The PSI officer will typically interview the defendant in person. That interview is not a casual conversation — what you say can appear verbatim in the report the judge reads. For this reason, it is critical to have spoken with your attorney before the PSI interview.

Once the report is complete, both the defense and the prosecution receive a copy and have the right to challenge factual inaccuracies. If you believe something in the PSI is wrong — a prior conviction that was expunged, a misquoted statement, or an error in your employment history — your attorney can bring that to the court's attention at the hearing. Judges rely heavily on accurate PSI information, so correcting errors is not a minor procedural point; it can directly affect your sentence.

Illinois law gives crime victims a protected right to be heard at sentencing. Under the Illinois Rights of Crime Victims and Witnesses Act (725 ILCS 120/), and reinforced by the Illinois Constitution's Crime Victims' Rights Amendment (Article I, Section 8.1), victims may submit written statements and, in many cases, address the court in person.

What a victim impact statement can include:

• A description of the physical, emotional, and financial harm caused by the offense
• The effect of the crime on the victim's family and daily life
• The victim's opinion about the appropriate sentence, including restitution requests

The Cook County State's Attorney's Office has a dedicated Victim Services unit that assists victims in preparing and presenting these statements. Judges take them seriously, and they can influence the sentence — particularly when the harm described is severe or lasting.

From the defense perspective, the hearing is not a one-sided proceeding. Your attorney has the right to respond to anything presented by the prosecution, and the defense may offer its own evidence and witnesses. That said, victim statements are not subject to cross-examination the way trial testimony is, so the defense response must be measured and respectful. Acknowledging the victim's harm — without necessarily conceding every characterization — is often a more effective approach than a combative one.

Restitution is a related issue that often surfaces at this stage. If the victim suffered quantifiable financial losses, the court may order restitution as part of the sentence. Under 730 ILCS 5/5-5-6, restitution is mandatory in certain cases, and the judge will consider evidence of the victim's actual losses.

Illinois law creates a layered framework of sentencing ranges. Understanding those layers helps you — and your family — form realistic expectations.

Statutory Sentencing Ranges by Felony Class (730 ILCS 5/5-4.5)

Note: Some offenses carry specific statutory ranges that differ from the general class range. Always verify the exact range that applies to your charge.

Mandatory minimums exist for certain offenses — particularly drug trafficking, firearms offenses, and crimes involving great bodily harm. When a mandatory minimum applies, the judge has no discretion to go below that floor, regardless of how sympathetic the mitigating circumstances may be.

Extended-term sentencing can increase the ceiling of the sentencing range when specific aggravating factors are present under 730 ILCS 5/5-8-2. Triggers include a prior conviction of the same or greater class within the past ten years, the victim being a person with a physical or intellectual disability, or the offense being accompanied by exceptionally brutal or heinous behavior. An extended-term sentence for a Class 1 felony, for example, can reach up to 30 years instead of the standard 15.

Truth-in-sentencing is another layer that affects how much of a prison sentence a person actually serves. Illinois eliminated parole for most offenses committed on or after June 19, 1998. Under 730 ILCS 5/3-6-3, many offenders must serve at least 85 percent of their sentence before release. For certain violent offenses — including murder, attempted murder, and aggravated criminal sexual assault — the law requires serving 100 percent of the sentence imposed. This is a critical distinction: a five-year sentence for a non-violent offense and a five-year sentence for a qualifying violent offense represent very different amounts of actual time in custody. The Illinois Department of Corrections (IDOC) administers these rules and publishes information about sentence credit policies on its official website.

Misdemeanor sentences work differently. A Class A misdemeanor carries up to 364 days in the Cook County Jail (not a state prison) and up to two years of probation. Class B and Class C misdemeanors carry shorter maximum jail terms.

One of the most important realities of Illinois sentencing is that — within the statutory range — the judge has significant discretion. That discretion is shaped by mitigating and aggravating factors listed in 730 ILCS 5/5-5-3.1 and 730 ILCS 5/5-5-3.2. Your defense attorney's job at the sentencing hearing is to build a compelling, evidence-based argument around the mitigating factors and, where possible, address or minimize the aggravating ones.

Common statutory mitigating factors include:

• No prior criminal history, or a minimal criminal record
• The offense was a result of circumstances unlikely to recur
• The defendant's conduct neither caused nor threatened serious physical harm
• Substantial grounds to excuse or justify the conduct (even if not a full legal defense)
• The defendant acted under strong provocation
• The defendant's youth at the time of the offense
• Genuine remorse or willingness to make restitution
• Addiction or mental health conditions that contributed to the conduct
• The defendant's role was minor compared to a co-defendant's

Common statutory aggravating factors include:

• The defendant caused or threatened serious harm
• Prior criminal history
• The defendant was on probation, parole, or supervision at the time of the offense
• The offense was motivated by the victim's race, religion, national origin, gender, or sexual orientation (a hate crime enhancement)
• The defendant held a position of trust or authority over the victim

In practice, Cook County sentencing hearings can involve witness testimony, letters of support from employers, family members, teachers, or clergy, documentary evidence such as educational records or proof of treatment completion, and expert testimony regarding mental health or substance use disorders. The defense may also call the defendant to make a statement — a right protected under Illinois law — though this decision requires careful strategic thought.

Presentence mitigation memos are another powerful tool. These are written documents prepared by the defense that summarize the defendant's background, highlight mitigating factors, and argue for a specific sentence or sentencing alternative. They are especially common in Cook County felony practice and can make a meaningful difference when a judge is deciding between prison and probation or weighing the length of a prison term.

The Cook County Public Defender's Office — one of the largest public defender offices in the country — has social workers and mitigation specialists on staff specifically to help build this type of record for clients who qualify. Regardless of who represents you, the quality of mitigation preparation at this stage is one of the most consequential variables in the entire case.

Prison is not the only possible outcome for a felony conviction in Illinois. For many offense classes and fact patterns, the judge may impose probation instead of — or in combination with — a period of incarceration. Understanding when probation is available, and how to pursue it effectively, is a central part of sentencing strategy.

Under 730 ILCS 5/5-6-1, a court may sentence an eligible defendant to a term of probation in lieu of imprisonment. For most Class 2, 3, and 4 felonies and for misdemeanors, probation is a genuine option. For Class 1 felonies, probation is available in many (though not all) cases. For Class X felonies and certain specific offenses, the legislature has made probation unavailable regardless of the circumstances.

Conditions of probation commonly imposed in Cook County include:

• Regular reporting to a Cook County Adult Probation officer
• Drug and alcohol testing
• Substance use or mental health treatment
• Community service hours
• Payment of fines, fees, and restitution
• No new arrests or criminal conduct
• Restrictions on travel or associations
• Electronic monitoring (GPS ankle bracelet) in some cases

Violating probation conditions can result in a revocation hearing and the imposition of the original prison sentence, so compliance is essential.

Other alternatives the court may consider:

• Conditional discharge — similar to probation but without a supervision officer, available under 730 ILCS 5/5-6-3.3 for eligible cases
• Drug court — Cook County operates specialized drug courts that focus on treatment and accountability rather than punishment; a successful completion can result in a reduced sentence or dismissal
• Mental health court — available for defendants whose offenses are linked to an untreated mental health condition
• Boot camp / impact incarceration — an intensive short-term program that can substitute for a longer prison term in qualifying cases

If you are weighing a guilty plea, understanding all available sentencing alternatives — and whether the proposed plea agreement forecloses any of them — is essential before agreeing to anything. The sentencing hearing is often the last meaningful opportunity to shape the outcome, and arriving prepared makes all the difference.
