A 42-year-old Chicago man is facing attempted first-degree murder charges after allegedly stabbing another man multiple times following an argument outside a Jewel-Osco on the southwest suburb's Ridgeland Avenue, according to police. Michael Duplessis Jr. was ordered held awaiting trial at a detention hearing Monday and is due back in court Wednesday.
The confrontation began when Duplessis argued with another man near the Jewel-Osco at 8757 South Ridgeland Avenue, police said. According to the Chicago Sun-Times, Duplessis spat on the other man during the dispute, and the two then got into a physical fight. Police allege that Duplessis stabbed the man multiple times during the altercation.
The injured man was rushed to Christ Medical Center in critical condition and underwent emergency surgery, police said. Advocate Christ Medical Center in Oak Lawn operates the busiest Level I Trauma Center in Illinois, treating more than 4,000 trauma patients and over 100,000 emergency patients annually, according to Advocate Health, underscoring the hospital's role as a regional trauma hub for Chicago's South Side and southwestern suburbs.
A Recent Record of Violence
Court records show this isn't Duplessis's first brush with Illinois's violent crime statutes. He was charged in November 2025 with aggravated battery of a victim over 60 years old and was sentenced to one year in prison, receiving credit for 194 days served while the case was pending. He was released earlier in 2026, not long before the alleged stabbing near the Jewel-Osco.
Aggravated battery against a victim 60 or older is codified as a Class 2 felony under Illinois law, carrying a standard sentencing range of three to seven years in state prison, per the Chicago Criminal Defense Lawyer firm's breakdown of the statute. Under Illinois sentencing guidelines, individuals released after serving a Class 2 felony sentence remain subject to mandatory supervised release, according to the Illinois sentencing code as compiled by FindLaw.
What Attempted Murder Charges Mean in Illinois
Attempted first-degree murder is classified as a Class X felony in Illinois, carrying a mandatory prison sentence of 6 to 30 years upon conviction with no eligibility for probation, according to the Law Offices of James F. DiQuattro. To secure a conviction, prosecutors must prove beyond a reasonable doubt that Duplessis acted with specific intent to kill rather than merely intending serious harm, a standard reaffirmed by the Illinois Supreme Court in People v. Guy, as detailed by legal research platform CaseMine.
Duplessis's detention without bail stems from Illinois's Pretrial Fairness Act, the state law that eliminated cash bail in September 2023. Under the act, judges may order defendants held without bail before trial for non-probationable forcible felonies like attempted murder if prosecutors show the defendant poses a specific threat to public safety, according to legal materials compiled by the Office of the State Appellate Defender.
Case Heads to Bridgeview Courthouse
Criminal proceedings stemming from Oak Lawn police arrests fall under the Cook County Circuit Court's Fifth Municipal District, based at the Bridgeview Courthouse, according to the Circuit Court of Cook County.
Oak Lawn is a southwestern Cook County suburb bordering Chicago's South Side.
The current status of the man stabbed near the Jewel-Osco has not been disclosed beyond his critical condition following surgery. Duplessis remains in custody ahead of Wednesday's court date.
