ORDER

¶1 Held: The appellate court affirmed defendant’s convictions for first degree murder, intentional homicide of an unborn child, and residential arson, where the trial court did not abuse its discretion in (1) allowing the jury to watch a four-hour video recording of defendant’s police interrogation, (2) prohibiting defense counsel from impeaching a police officer with his grand jury testimony, and (3) allowing defendant’s coworkers to testify. Additionally, because the court committed no error, there could be no cumulative error.

¶2 Defendant, Matthew T. Plote, was charged with first degree murder of Melissa Lamesch, the mother of his unborn child (720 ILCS 5/9-1(a)(1), (2) (West 2020)), intentional homicide of his unborn child (720 ILCS 5/9-1.2(a)(1), (2) (West 2020)), residential arson (720 ILCS 5/20-1(b) (West 2020)), aggravated domestic battery (720 ILCS 5/12-3.3(a-5) (West 2020)), and concealment of a homicidal death (720 ILCS 5/9-3.4(a) (West 2020)). Following a trial, the jury found defendant guilty of all charges. After determining that the aggravated domestic battery conviction merged with the first degree murder conviction and the concealment of a homicidal

death conviction merged with the residential arson conviction, the trial court sentenced defendant to concurrent prison terms of life for first degree murder, 60 years for intentional homicide of an unborn child, and 15 years for residential arson. Defendant appeals, arguing that (1) the court erred in allowing the State to play a four-hour video of his police interrogation, (2) the court improperly prohibited his counsel from impeaching a police officer with his grand jury testimony, (3) the testimony of his coworkers was more prejudicial than probative, and (4) “the cumulative effect of multiple errors deprived [him] of a fair trial.” For the reasons that follow, we affirm.

¶3 I. BACKGROUND

¶4 On November 25, 2020, Melissa was living with her father, Gustave Lamesch, at his home on South Hannah Avenue in Mount Morris, Illinois. Melissa was pregnant and scheduled to be induced two days later. At approximately 4:30 p.m., a neighbor noticed smoke coming from the Lamesches’ house and called 911. Firefighters found Melissa dead on the floor in the kitchen. That evening, police interviewed defendant. On August 28, 2021, police interviewed defendant again, this time for more than seven hours.

¶5 On March 8, 2022, the State presented evidence and testimony to the grand jury, seeking an indictment against defendant. Lieutenant Brian Ketter of the Ogle County Sheriff’s Office testified before the grand jury that he investigated Melissa’s death. As part of his investigation, he learned that Melissa’s sister, Cassandra Baal, called Melissa “around 10:00” a.m. on November 25, 2020, and talked to her for “two hours and 22 minutes.” Ketter testified: “Towards the end of the call, Melissa told Cassandra, ‘Matthew’s here. He needs to stop doing this.’ ” During the course of his investigation, Ketter learned that “Matthew” was defendant. The grand jury issued a 10-count indictment against defendant, charging him with 4 counts of first degree murder (counts I through IV), 3 counts of intentional homicide of an unborn child (counts

V through VII), and 1 count each of residential arson (count VIII), aggravated domestic battery (count IX), and concealment of a homicidal death (count X).

¶6 On November 17, 2023, defendant filed a motion in limine, requesting the trial court prohibit the State from “introducing any evidence of [his] silence” during the August 28, 2021, interrogation. The State filed a response to the motion, explaining that it did not intend to play portions of the interrogation during which defendant did “not actively participate” but asserting that the remainder of the interview, including defendant’s silence, was “relevant.” On March 7, 2024, the court entered an order denying defendant’s motion in limine. The court reasoned that defendant’s failure to explicitly and unambiguously invoke his right to remain silent during the interrogation constituted a waiver of that right.

¶7 Defendant’s jury trial took place over five days in March 2024. The evidence at trial revealed the following. In October 2020, Melissa moved in with her father. Troy Clayton, who lived directly across the street from the Lamesches, testified that “some time around 1:30” p.m. on November 25, 2020, he saw “a white male in his mid 20’s, early 30’s walking down the street” wearing a hat and a “blue Armorall [sic] backpack.” The man walked “right up the driveway and knocked on the front door” of the Lamesches’ house. Clayton “watched Melissa open the door and let him in.” Clayton had never seen the man before and denied seeing anyone else he did not recognize in the neighborhood that day. Clayton denied seeing any cars he was not familiar with parked on Hannah Street on November 25, 2020.

¶8 Another neighbor noticed smoke coming from the Lamesch home at approximately 4:30 p.m. and called 911. Firefighters from the Mount Morris Fire Protection District quickly responded to the fire. When they arrived, they saw a great deal of smoke coming from the roof of the home. All windows and doors to the Lamesch home were locked when firefighters arrived.

Firefighters forced open the front door and located Melissa on the floor in front of the refrigerator with debris on top of her.

¶9 Gustave testified that Melissa moved in with him in October 2020 to save money in preparation for the birth of her baby. Melissa did not tell him who the baby’s father was, and Gustave had neither met nor spoken to defendant. Gustave did not notice anything missing from his house after the fire.

¶ 10 Two forensic pathologists performed autopsies on Melissa: Dr. Mark Peters and Dr. Amanda Youmans. They both concluded that Melissa’s cause of death was “strangulation.” They both also identified many predeath bruises on Melissa’s legs and thighs, as well as contusions on her scalp caused by “impacts” or “blows” to her head. The pathologists also found contusions and abrasions in Melissa’s vagina, which Peters thought could be consistent with “vaginal sexual intercourse.” However, Youmans believed those injuries were “consistent with sexual assault,” rather than “consensual sex.”

¶ 11 Both Peters and Youmans determined that Melissa was not alive when the fire started because she had no soot in her lungs and a normal level of carbon monoxide in her blood. Both pathologists testified that Melissa was pregnant with a healthy, full-term male fetus at the time of her death. Youmans testified that the fetus died shortly after Melissa when blood stopped flowing to the umbilical cord.

¶ 12 A sexual assault kit was prepared, with swabs taken from Melissa’s vagina and anus. Fingernail scrapings were also taken from both of Melissa’s hands.
