Berly Valladares was convicted of first-degree murder and aggravated battery with a firearm in connection with a Halloween 2009 shooting that killed Francisco Valencia and wounded Daisy Camacho at a house party. As a gang member and the gang's 'gun holder,' Valladares admitted providing a loaded firearm to shooter Narcisco Gatica, knowing it would be used for retaliation. The trial court sentenced Valladares to 70 years in prison, with the judge specifically noting his 'prior conviction was for a weapons offense' when explaining why Valladares posed a danger to society.

The appellate court found that the sentencing court's reliance on Valladares's 2007 aggravated unlawful use of a weapon (AUUW) conviction violated due process because that conviction was void under People v. Aguilar, which held the underlying statute facially unconstitutional. Justice Hyman wrote that the sentencing court 'agreed with the State that he was a "danger" because he "obviously deals with guns and violence" and noted that "[h]is prior conviction was for a weapons offense."' The court emphasized that 'even when a sentencing court properly considers multiple factors, the State's introduction of a void prior conviction as an aggravating factor is substantial enough to warrant resentencing.'

The court delivered particularly strong language about the improper use of void convictions, stating that 'for several years, our courts sustained a maze of rules and procedures petitioners had to navigate to vindicate their rights.' Justice Hyman noted that the State had 'leaned on Valladares's void conviction to paint him as a criminal with a record of gun crime,' and that prosecutors argued the AUUW conviction showed Valladares was a 'murderer who doesn't care what happens with guns' who 'will pass out guns to whomever.'

The case arose when Valladares successfully vacated his 2007 AUUW conviction in September 2023 and then sought leave to file a successive postconviction petition challenging his sentence. The circuit court initially denied his request, finding that the void conviction played only an 'insignificant role' in sentencing. However, Valladares had faced procedural hurdles in raising his claim earlier because when he filed his initial postconviction petition in 2014, controlling caselaw prevented him from challenging the void conviction in a petition attacking his separate 2009 conviction.

The appellate court rejected the State's argument that Valladares could have raised the issue earlier, finding he established 'cause' for filing a successive petition because 'at the time he filed his initial postconviction petition in 2014, caselaw precluded him from seeking to vacate his 2007 conviction in a petition collaterally attacking his 2009 conviction.' Justice Hyman explained that until the Illinois Supreme Court's 2018 decision in In re N.G., defendants faced legal barriers to challenging void convictions used at sentencing, noting that 'for many years, after Aguilar, even our courts could not agree on how a petitioner should proceed with an Aguilar-based claim.'

Justice Gamrath wrote a special concurrence acknowledging the difficulty of the case, noting that Valladares received a 'midrange sentence of 70 years' within his sentencing range of 41 to 105 years, and that defense counsel had acknowledged a life sentence was unavoidable. Justice Gamrath emphasized that while the void AUUW conviction 'appears minor,' the court mentioned it at sentencing, making resentencing necessary. He wrote that 'it is more prudent to remand for a resentencing, where the trial court may impose the same sentence or a different one' than to guess at a conviction's impact.

The court reversed and remanded for a new sentencing hearing, though it emphasized that 'nothing in our decision diminishes the seriousness of the offense or the harm suffered by the victims and their family.' The ruling comes as Illinois courts continue to grapple with the aftermath of void weapon convictions under Aguilar, with defendants seeking to challenge sentences that relied on those invalidated convictions years after their initial appeals concluded.
