In People v. Pasch, 152 Ill. 2d 133, 604 N.E.2d 294, 178 Ill. Dec. 38 (1992) the defendant was convicted of murdering a plain clothes police officer. The defendant shot his landlord in his yard, and then took a woman hostage inside an apartment. He then shot the officer (who arrived in an unmarked car and never announced his office) from inside the apartment. The evidence showed that the defendant turned his head in the direction from which police sirens were coming before he ran inside the apartment, and that at least one squad car pulled up near the building he was in. The defendant told a police officer that he had shot two people, one of whom was a cop. The court noted that "logic also dictates that defendant knew or should have known that the police were informed of" the first shooting and "that it would just be a matter of minutes" before their arrival. Pasch, 152 Ill. 2d at 215. The court held that the evidence showed beyond a reasonable doubt that the defendant knew or should have known the decedent was a police officer.
