Illinois Homicide & Attempted Murder Charges We Defend
- First-Degree Murder (720 ILCS 5/9-1): Allegations involving intentional killing, knowing conduct creating a strong probability of death or great bodily harm, or deaths occurring during the commission of a forcible felony (Felony Murder).
- Attempted First-Degree Murder (720 ILCS 5/8-4 & 5/9-1): Cases where prosecutors allege specific intent to kill, often carrying Class X felony penalties plus mandatory 15-, 20-, or 25-years-to-life firearm enhancements.
- Second-Degree Murder & Involuntary Manslaughter (720 ILCS 5/9-2 & 5/9-3): Mitigating first-degree allegations through imperfect self-defense or sudden and intense passion, or challenging reckless conduct claims.
Defense Strategy at 26th & California
Homicide prosecutions in Chicago frequently rely on flawed eyewitness identifications, coerced or inconsistent stationhouse statements, cell-site location information (CSLI), and contested forensic ballistics. Our defense strategy focuses on dismantling the State's case before it ever reaches a jury:
- Pretrial Detention Hearings (SAFE-T Act): Challenging the State’s petition to detain at initial appearance hearings and building an evidentiary record early.
- Motions to Suppress Statements & Evidence: Attacking Fifth Amendment Miranda violations, prolonged custodial interrogations, and Fourth Amendment warrant defects.
- Affirmative Defenses & Forensic Challenges: Investigating self-defense (720 ILCS 5/7-1), challenging DNA transfer and gunshot residue (GSR) assumptions, and cross-examining gang-motive theories.
Frequently Asked Questions
What is the sentencing range for First-Degree Murder in Illinois?
First-Degree Murder carries a base sentencing range of 20 to 60 years in the Illinois Department of Corrections, served at 100% under Illinois Truth-in-Sentencing laws. If a firearm is discharged and causes great bodily harm or death, Illinois law mandates an additional 25 years to natural life on top of the base sentence.
Can a First-Degree Murder charge be reduced to Second-Degree Murder?
Yes. Under 720 ILCS 5/9-2, if the defense establishes by a preponderance of the evidence that the defendant acted under a sudden and intense passion resulting from serious provocation, or held an unreasonable belief that deadly force was necessary in self-defense, the offense may be reduced to Second-Degree Murder—a Class 1 felony carrying 4 to 20 years (or probation in certain circumstances).
How does the Illinois Felony Murder rule work?
Under Illinois's amended Felony Murder statute (720 ILCS 5/9-1(a)(3)), a person can only be convicted of Felony Murder if they—or another participant acting with them—personally caused the death of a person during the commission or attempt of a forcible felony. Prosecutors can no longer charge a defendant with murder solely because a third party (such as police or a bystander) fired the fatal shot.
