In People v. DeGeer, 140 Mich App 46; 363 NW2d 37 (1985), the defendant made a telephone call from the booking desk of the county jail, and a sign located near the telephone stated that all conversations would be recorded. The trial court denied the defendant's motion to suppress incriminating statements made while using the telephone, ruling that defendant had only a limited expectation of privacy in the conversation. On appeal, the defendant argued that he had not seen the sign warning that his telephone call would be recorded. The Court held that the defendant was on reasonable notice that his telephone conversation might be monitored and affirmed the trial court's decision denying defendant's motion to suppress. Id. at 47-48.
