2022 IL App (1st) 201151
Ill. App. Ct.2022Background
- Brian Walker, age 20 at the time of the offense, was convicted by a jury of first‑degree murder for shooting Dehombre Barnett; jury found he personally discharged the firearm.
- Walker gave a signed statement that he went to buy marijuana, accompanied co‑offender Matthew Moss, panicked when the victim displayed a gun, and fired two shots; the victim died from a shot above the left temple.
- Walker was initially sentenced to 35 years plus a mandatory 25‑year firearm enhancement (60 years); after appeals and remands the trial court ultimately imposed 28 years + 25‑year enhancement (53 years).
- Walker filed multiple postconviction and collateral petitions previously; in March 2020 he sought leave to file a successive postconviction petition arguing his 53‑year sentence, imposed for conduct at age 20, violates the Illinois Constitution’s proportionate penalties clause in light of evolving juvenile/young‑adult neuroscience and caselaw.
- The trial court denied leave to file; Walker appealed, arguing he showed cause and prejudice to pursue a successive petition based on recent legal and scientific developments. The appellate court affirmed, finding Walker failed to show cause.
Issues
| Issue | Plaintiff's Argument (People) | Defendant's Argument (Walker) | Held |
|---|---|---|---|
| Whether Walker made a prima facie showing of cause and prejudice to obtain leave to file a successive postconviction petition challenging his 53‑year sentence under the Illinois proportionate penalties clause | Dorsey and settled Illinois precedent show Miller and related developments do not create "cause" to bring a new state constitutional claim; differences between minors and adults were already recognized, so no new basis exists | Recent U.S. and Illinois decisions plus neuroscience research about young‑adult brain development supply a new basis to treat a 20‑year‑old’s sentence as an as‑applied challenge under the Illinois proportionate penalties clause | Leave denied: Walker failed to establish cause; court did not reach prejudice |
