Background
A jury found Lamontreal Glinsey guilty of first-degree murder under an accountability theory for his role in a gang-related shooting that killed an innocent bystander. Glinsey committed the offense 11 days after turning 18. Although a codefendant fired the fatal shots, Glinsey admitted firing earlier shots toward the same area. The trial court sentenced him in 2000 to 45 years in prison, to be served at 100%.
In his third successive postconviction petition, Glinsey alleged that the sentence violated Illinois’s proportionate penalties clause as applied to him because he was developmentally more like a juvenile than an adult. His amended petition included a psychologist’s individualized mitigation report describing his exposure to poverty, violence, abuse, gangs, and trauma; research concerning young-adult brain development; and evidence of rehabilitation during incarceration. The circuit court dismissed the petition at the second stage, concluding that then-controlling precedent prevented Glinsey from establishing cause for failing to raise the claim earlier.
The Court’s Holding
The appellate court reversed and remanded for a third-stage evidentiary hearing. While the appeal was pending, Illinois amended the Post-Conviction Hearing Act to provide that a person convicted of a felony committed before age 21 need not establish cause when seeking leave to file a successive petition alleging that the sentence violates the Illinois Constitution’s proportionate penalties clause. Following People v. Sparkman, the majority held that the amendment applied retroactively because it removed only a procedural barrier.
The majority also held that Glinsey established prejudice and made a substantial showing of an as-applied constitutional violation. His supporting materials specifically connected his childhood circumstances and incomplete development to his susceptibility to gang influence and peer pressure, documented his rehabilitative capacity, and showed that this mitigation was not considered at sentencing. The discretionary nature of his 45-year sentence did not defeat the claim because Illinois law permits a proportionate-penalties challenge to a sentence of any length. Presiding Justice Ellis dissented, reasoning that the statutory amendment eliminated the cause requirement but did not excuse Glinsey’s failure to preserve the constitutional claim at sentencing.
Key Takeaways
- The 2026 amendment eliminating the cause requirement for qualifying youth-based successive postconviction claims applies retroactively as a procedural change.
- A young adult may challenge a discretionary sentence under the proportionate penalties clause; the sentence need not be mandatory life imprisonment.
- An individualized expert report, developmental research, previously unpresented mitigation, and rehabilitation evidence can support advancement to a third-stage evidentiary hearing.
Why It Matters
The decision permits defendants who committed felonies before age 21 to pursue successive postconviction challenges without showing cause, provided they can still establish prejudice and sufficiently plead an as-applied proportionate penalties violation. It also confirms that discretionary sentencing does not categorically foreclose claims grounded in young-adult developmental science.
The ruling does not vacate Glinsey’s sentence or grant resentencing. It requires an evidentiary hearing at which the circuit court can assess the evidence supporting his constitutional claim. The order was issued under Illinois Supreme Court Rule 23 and is nonprecedential except in the limited circumstances permitted by Rule 23(e)(1).
