IN THE SUPREME COURT OF THE STATE OF ILLINOIS

(Docket No. 131340)

THE PEOPLE OF THE STATE OF ILLINOIS, Appellant, v. WILLIAM P. HEINTZ, Appellee.

Opinion filed January 28, 2026.

JUSTICE THEIS delivered the judgment of the court, with opinion.

Justices Overstreet, Holder White, and Rochford concurred in the judgment and opinion.

Justice O’Brien specially concurred, with opinion, joined by Chief Justice Neville and Justice Cunningham.

OPINION

¶1 At issue in this appeal is whether evidence of Brianne Szalaj’s alleged violent conduct that postdated the charged offenses against defendant, William Heintz, was admissible under Illinois Rule of Evidence 405(b)(2) (eff. Jan. 1, 2011). Additionally, we must consider whether the Kankakee County circuit court abused its discretion in barring evidence that defendant was acquitted of one of the four prior alleged acts of domestic violence against Szalaj, which was introduced by the State at trial. The appellate court vacated defendant’s convictions and remanded for a new trial. 2024 IL App (3d) 230161-U, ¶ 39. For the reasons that follow, we reverse the appellate court’s judgment and remand to the appellate court to consider defendant’s remaining claims.

¶2 BACKGROUND

¶3 Defendant was charged in connection with his conduct toward Szalaj on August 6, 2020, with attempted first degree murder (720 ILCS 5/8-4(a), 9-1(a) West 2020)), aggravated domestic battery (id. § 12-3.3(a-5)), unlawful restraint (id. § 10- 3(a)), and domestic battery (id. § 12-3.2(a)(1)).

¶4 Prior to trial, the State and defendant both sought leave to introduce evidence of other acts of violent conduct committed during defendant’s multiyear relationship with Szalaj.

¶5 The State filed a motion in limine, pursuant to section 115-7.4 of the Code of Criminal Procedure of 1963 (Code) (725 ILCS 5/115-7.4 (West 2020)). That statute applies in domestic violence cases and allows the admission of “evidence of the defendant’s commission of another offense or offenses of domestic violence,” which can be considered for any relevant purpose. See id. § 115-7.4(a). The State sought to admit testimony detailing defendant’s previous alleged acts of domestic battery. The trial court granted the State’s motion and allowed evidence of four separate incidents that all occurred prior to the charged offenses in this case. The first incident occurred in February 2019, the second in July 2019, the third in February 2020, and the fourth on July 3, 2020. In the fourth incident, defendant was charged with domestic battery and was later acquitted of the charge.

¶6 Defendant also filed a motion in limine to introduce home surveillance videos showing two separate incidents to illustrate the alleged violent character of Szalaj. One set of videos was taken on November 5, 2020, three months after the charged offenses in this case, and showed Szalaj throwing a beer can at defendant’s face. The second set of videos was taken on February 9, 2021, and showed Szalaj

-2- straddling defendant’s body, hitting him with her purse and punching him. The trial court denied defendant’s motion in limine because the conduct recorded in the videos postdated the charged offenses.

¶7 A jury trial commenced on December 12, 2022. During opening arguments, defense counsel stated, inter alia, that Szalaj had defendant arrested for misdemeanor domestic battery in relation to an incident on July 3, 2020, and that he was tried on the offense in Iroquois County. The court sustained the State’s objection.

¶8 The evidence established that Szalaj and defendant began a relationship after meeting at work around 2017. The two maintained separate residences. Defendant lived in Iroquois County, and Szalaj lived in Kankakee County. Over the course of their relationship, they began to fight, accusing each other of infidelity. The couple would repeatedly break up and then reconcile.

¶9 Szalaj testified that on August 5, 2020, she returned to her home after 10 p.m. to find defendant waiting for her in the kitchen. He demanded her cell phone, and when she refused, he grabbed her upper lip, causing it to bleed. She fled upstairs to the bathroom and locked the door. Defendant then kicked the door down, threw her into the bathtub, stepped on her neck and chest, and began to run water over her face. Defendant had her cell phone and repeatedly told her that, if she would give him the password, he would stop. Defendant became more forceful and stepped on her neck again. Szalaj could not breathe and blacked out.

¶ 10 Szalaj further testified that, when she regained consciousness, defendant was beating her and punching her in the face. He held her head under the running water and demanded her password. Defendant pulled out a knife and threatened to kill her. Szalaj raised her hand, and defendant cut her thumb. She testified that she was held in the bathroom for hours. Eventually, defendant let her out of the bathroom, and she went to sleep. She further testified that she had screamed for help out of her bedroom window. Defendant told her they would discuss it later and instructed her to go to bed. When she woke up in the morning, defendant was still there. Szalaj was able to log on to her work computer and send a message to a coworker to send the police. When the police arrived, defendant fled out the garage door.

-3- ¶ 11 Szalaj’s blood was found on defendant’s shirt, and her phone was in defendant’s car. Police took photographs of her injuries, including a black eye, a bleeding lip, marks on her chest, a cut on her thumb, and bruises all over her body. The police photographed the bathroom door and the blood in the bathtub. After the attack, Szalaj found the knife under her bed. DNA from both Szalaj and defendant was found on the knife.

¶ 12 Defendant advanced a claim of self-defense. He testified that the two were still in a relationship in August 2020 and were planning to meet at Szalaj’s home on the evening of August 5. When he arrived there after midnight, she was sleeping, and he woke her. He questioned Szalaj and asked to see her cell phone because her answers were evasive. Defendant testified that he grabbed her cell phone, saw that she had changed her password, and asked why. Szalaj then grabbed defendant’s cell phone, threw a beer in his face, and fled to the bathroom with his phone. Defendant chased her, he used his body to “hit [the door] with some force,” and the doorjamb “popped.” After he forced the door open, Szalaj began to punch him and tried to knee him in the groin. He grabbed her arms to protect himself, and she fell into the tub during the struggle. He testified that he pinned her in the tub with his boot. When he let her up, she began punching him again. The two fell back into the tub, and he put his boot on her chest to restrain her until she settled down. Defendant denied that he slapped, kneed, or kicked Szalaj or stepped on her neck. Eventually she stopped fighting, and they went to bed.

¶ 13 Defendant called Jeff Wedwick without objection by the State. He testified that he was a longtime friend of defendant’s father. Wedwick testified that he and his wife went on a trip to Mexico with defendant and Szalaj in February 2019. During the trip, he observed Szalaj approach defendant from behind at a bar and said she “cracked him in the back of the head.”

¶ 14 Consistent with the trial court’s ruling on the motion in limine, Szalaj and defendant both testified about four other occasions of domestic violence that all occurred prior to the charged offenses in this case. The first incident occurred in February 2019. Szalaj testified that she and defendant were at his home.
