In People v. Henderson, 142 Ill. 2d 258, 299, 568 N.E.2d 1234, 154 Ill. Dec. 785 (1990), the supreme court affirmed the trial court's finding of consent where police entered an apartment, identified themselves and asked if the defendant was home. Defendant's mother answered the door, confirmed that defendant was inside and stepped back from the open door and pointed toward defendant's bedroom. As demonstrated by Henderson, consent can be given in the form of either gestures or conduct as well as by the spoken word. Henderson, 142 Ill. 2d at 298-99; See also: People v. Gross, 166 Ill.
