Williams, 467 U.S. 431, 448 (1984)). ¶ 62 Defendant argues that the inevitable discovery doctrine does not apply because the information the officers used to secure the warrant was obtained after their unlawful entry into

2025However, the trial court determined, pursuant to the inevitable discovery doctrine, that suppression of the evidence obtained from the cellphone was not warranted because the officers did not search the cellphone based on either the passcode or signed consent form, but rather based on a signed search warrant. ¶ 61 “The ‘inevitable discovery doctrine’ was developed as an exception to the exclusionary rule, which requires exclusion from use at a criminal trial illegally obtained evidence.” People v. Edwards, 144 Ill. 2d 108, 143 (1991).
