Experienced Felony Defense When the Stakes Are at Their Highest
A felony charge in Joliet is the most serious type of criminal accusation you can face in Illinois. Unlike misdemeanors, a felony conviction means state prison — not county jail — along with fines up to $25,000, years of mandatory supervised release after prison, and a permanent criminal record that will affect every aspect of your life. Your right to vote, own firearms, hold professional licenses, and find employment are all at stake.
At the Law Offices of Jack L. Zaremba, P.C., we defend clients facing felony charges of all classes throughout Joliet, Will County, and Grundy County. Attorney Jack Zaremba is a former Will County prosecutor and Illinois Assistant Attorney General who has handled thousands of felony cases on both sides of the courtroom. He knows how prosecutors prioritize cases, build their evidence, and make charging decisions — and he uses that knowledge to fight for every client.
Illinois Felony Classifications and Sentencing Ranges
Illinois classifies felonies into six categories under the Unified Code of Corrections (730 ILCS 5/5-4.5). Each class carries specific sentencing ranges for prison time, probation eligibility, mandatory supervised release (MSR), and fines. Understanding where your charge falls is essential to evaluating your risk and making informed decisions about your defense:
Class 4 felony — The least severe felony classification. Prison: 1 to 3 years (extended term: 3 to 6 years). Probation: up to 30 months. MSR: 1 year. Examples in Joliet courts: aggravated DUI, retail theft with prior conviction, possession of a controlled substance, driving on a revoked license (DUI-related).
Class 3 felony — Prison: 2 to 5 years (extended term: 5 to 10 years). Probation: up to 30 months. MSR: 1 year. Examples: aggravated battery, possession by a felon, retail theft over $300, theft between $500 and $10,000.
Class 2 felony — Prison: 3 to 7 years (extended term: 7 to 14 years). Probation: up to 4 years. MSR: 2 years. Examples: aggravated domestic battery, aggravated DUI (3rd offense), burglary, aggravated unlawful use of a weapon by a felon.
Class 1 felony — Prison: 4 to 15 years (extended term: 15 to 30 years). Probation: up to 4 years for some offenses. MSR: 2 years. Examples: criminal sexual assault, aggravated discharge of a firearm, residential burglary, second-offense aggravated domestic battery with strangulation.
Class X felony — The most serious classification below first-degree murder. Prison: 6 to 30 years (extended term: 30 to 60 years). No probation eligibility. MSR: 3 years. Examples: armed robbery, home invasion, aggravated battery with a firearm against a police officer, drug trafficking of large quantities, sixth or subsequent DUI.
First-degree murder — Prison: 20 to 60 years (extended term: 60 to 100 years, or natural life). MSR: 3 years if released. This is a separate classification above Class X.
The maximum fine for most felonies in Illinois is $25,000. Courts may also order restitution to victims for financial losses resulting from the crime.
Common Felony Offenses Prosecuted in Will County
Will County prosecutors handle a wide range of felony cases. Some of the most common felony charges we defend in Joliet include:
- Drug offenses — Possession of controlled substances, possession with intent to deliver, drug trafficking, and manufacturing
- Aggravated DUI — Third or subsequent DUI, DUI causing great bodily harm or death, DUI with a suspended license
- Weapons offenses — Unlawful possession by a felon, aggravated unlawful use of a weapon, aggravated discharge of a firearm
- Aggravated battery — Battery causing great bodily harm, battery against a protected individual, battery with a deadly weapon
- Felony domestic battery — Repeat domestic battery, aggravated domestic battery involving strangulation
- Felony theft — Retail theft over $300, theft with prior convictions, identity theft, financial crimes
- Burglary and home invasion — Unauthorized entry with intent to commit a felony, armed home invasion
- Sex offenses — Criminal sexual assault, aggravated criminal sexual abuse
Extended Term Sentencing in Illinois
Illinois law allows judges to impose extended-term sentences that significantly increase the maximum prison time for a felony conviction. Under 730 ILCS 5/5-5-3.2, extended terms may be imposed when aggravating factors are present, including:
- The defendant has a prior felony conviction
- The offense was committed against a person 60 years of age or older
- The offense was exceptionally brutal or heinous
- The defendant held a position of trust relative to the victim
- The offense involved a firearm
- The offense was committed in furtherance of gang activity
Extended terms effectively double the maximum prison time for each felony class. For example, a Class 2 felony that normally carries a maximum of 7 years can carry up to 14 years under extended-term sentencing. Joliet prosecutors frequently seek extended terms in violent crime and repeat offender cases, which makes experienced defense representation critical.
Defense Strategies for Felony Charges
Felony cases in Will County are handled in the felony division of the Will County Courthouse in Joliet. As a former prosecutor who worked in these same courtrooms, Attorney Zaremba applies proven defense strategies tailored to each client’s case:
- Suppression of evidence — If police obtained evidence through an illegal search, traffic stop, or interrogation, we file motions to suppress that evidence. Without the suppressed evidence, the prosecution may be unable to prove its case.
- Challenging witness credibility — Many felony cases rely heavily on witness testimony. We investigate witnesses for bias, inconsistencies, prior statements, and motives to fabricate or exaggerate.
- Negotiating charge reductions — In some cases, we can negotiate with Will County prosecutors to reduce a felony charge to a misdemeanor, or to reduce the felony class. A Class 3 felony reduced to a Class 4, for example, can mean the difference between prison and probation.
- Pursuing probation over prison — For probation-eligible felonies, we present mitigating evidence and argue for community-based supervision instead of incarceration. Illinois law specifically requires courts to consider probation for Class 3 and 4 felony defendants with no prior violent convictions.
- Challenging the elements of the offense — Every felony has specific elements that the prosecution must prove beyond a reasonable doubt. We examine whether the State can actually prove each element with admissible evidence.
- Trial defense — When the evidence does not support a conviction or the State’s case has significant weaknesses, we take the case to trial. Attorney Zaremba prepares every felony case for trial from day one, which strengthens both trial outcomes and negotiation positions.
Frequently Asked Questions About Felony Charges in Joliet
Can a felony be reduced to a misdemeanor in Illinois?
In some cases, yes. Through plea negotiations, successful pretrial motions, or presentation of mitigating evidence, it may be possible to have a felony charge reduced to a misdemeanor. The outcome depends on the specific facts, the strength of the evidence, your criminal history, and the skill of your defense attorney. This is one of the most valuable results an experienced Joliet felony attorney can achieve.
Will I go to prison for a first felony conviction in Will County?
Not necessarily. Class 3 and Class 4 felonies are eligible for probation, and Illinois law directs courts to consider probation for defendants with no prior violent convictions. Many first-time felony offenders in Will County receive probation with conditions rather than prison time. However, Class X felonies and certain enhanced offenses carry mandatory prison sentences regardless of criminal history.
Can a felony conviction be expunged in Illinois?
Most felony convictions cannot be expunged under Illinois law. However, certain non-violent felony convictions may be eligible for sealing, which limits public access to the record. Additionally, successful completion of specific programs like Second Chance Probation (for drug offenses) can result in the conviction being vacated. An experienced attorney can evaluate whether your conviction qualifies for any form of relief.
What is mandatory supervised release?
Mandatory supervised release (MSR) is the Illinois equivalent of parole. After serving a prison sentence, you are released under supervision for a period of 1 to 3 years depending on the felony class. During MSR, you must comply with conditions set by the Prisoner Review Board. Violating MSR can result in being returned to prison.
