2023While the modus operandi exception recognizes that there will always be some differences between independent crimes (People v. Phillips, 127 Ill. 2d 499, 521 (1989)), it nevertheless requires a higher degree of similarity between the other crimes and the charged offense than any other generally recognized exception.

1992In People v. Phillips (1989), 127 Ill. 2d 499, 522 , 538 N.E.2d 500, 509 , the court affirmed the admission of the other crimes under the modus operandi exception based upon the trial court’s finding of 10 distinct areas of similarities between the crimes.
