People v. Beamangreen2 sentences2026To establish a Brady violation, a defendant must show that “(1) the undisclosed - 25 - No. 1-23-1497 evidence is favorable to the accused because it is either exculpatory or impeaching; (2) the evidence was suppressed by the State either wilfully or inadvertently; and (3) the accused was prejudiced because the evidence is material to guilt or punishment.” People v.

People v. Colemangreen2 sentences2022While we take Hemphill’s affidavit as true at this stage, we cannot add to it information that simply is not there. ¶ 35 Defendant also relies on People v.

People v. Velezgreen2 sentences2022Id. ¶ 16 In this case, the State concedes that the defendant’s petition established cause and prejudice as to his Brady violation claim and that his petition should be remanded to the trial court for further postconviction proceedings on that basis. 2009“To establish a Brady violation, the defendant must show (1) that the evidence was favorable to him, (2) that the prosecutor failed to disclose the evidence in response to a specific request, and (3) that the evidence was material.” People v.

Harris, 206 Ill. 2d 293, 311 (2002), quoting Brady, 373 U.S. at 87 ). 2025Brady Claim ¶ 170 Next, defendant argues that the trial court erred in dismissing his Brady claim that the State concealed evidence that Schaefer had enemies and at least one of them had abused her, stalked her, and made multiple threats to kill her. ¶ 171 Under Brady, it is a violation of the right to due process for the State to fail to “disclose evidence that is favorable to the accused and ‘material either to guilt or to punishment.’ ” People v.

People v.

People v.

Arizona v. Youngbloodgreen2 sentences1995The majority, however, would require a defendant to show bad faith on the part of the State only when the lost or destroyed evidence was not "potentially useful” to the defense and the evidence was not a component of the State’s case in chief. (166 Ill. 2d at 315.)
