delivered the opinion of the court:
The State appeals from an order of the Circuit Court of Du Page County suppressing a statement attributed to defendant, Jerry L. Davis. The statement was part of the State’s evidence in the prosecution of an information charging defendant with two counts each of theft and forgery. The court ruled that the evidence which provided the basis for defendant’s arrest was illegally obtained, as were the statements thereafter made while defendant was in custody.
At 11 a.m. on November 13, 1977, Detective John Poss of the Schaumburg Police Department received a telephone call from an informant relating that defendant was then in the process of manufacturing a silencer at the E-Z Grinding Company in Schaumburg. About a month previously, the informant had told Poss that defendant periodically made a silencer at the grinding company, and Poss had asked to be told if it happened again. After completing the November 13 telephone call, Poss and a second detective proceeded to the grinding company, arriving at about 12:20 p.m. A car was found parked behind the building, and a radio check disclosed it to be registered to defendant. The detectives had no warrant, but nevertheless entered through the main door of the building, which was closed but unlocked. It was a Sunday afternoon, and only defendant and an individual named Roy Black were present. Defendant worked part-time for the grinding company on a consignment basis. Defendant and Black were at a work bench across the room when the detectives entered. As he entered, Detective Poss observed defendant make a quick motion as if to drop something on the table, and Poss heard something strike it. Poss testified at the hearing on the motion to suppress that he found a closed but unlocked briefcase on the work bench. Defendant testified, on the other hand, that the briefcase was 15 feet from his place at the work bench and was examined by Poss without permission. The detectives then conducted a pat-down of Black and the defendant. Poss opened the case and found an automatic pistol and a silencer inside. Poss then placed defendant under arrest. Defendant testified that the briefcase belonged to Roy Black, although he admitted using it.
Defendant was taken to the Schaumburg police station, where at 4 o’clock he was questioned by agents of the Federal Bureau of Alcohol, Tobacco and Firearms concerning a possible weapons charge. Defendant testified that he was read Miranda rights prior to this questioning, although the details of that advisement were not made a matter of record. At the conclusion of this interview, defendant said he was questioned by Detective Thomas Fries of the Schaumburg police department concerning the forgery and theft charges. Fries, however, testified that he questioned defendant prior to the arrival of the Federal agents. In either event, Fries testified that he had advised defendant fully in compliance with Miranda prior to questioning, and that defendant had indicated that he understood his rights and desired to waive them. Defendant denied having been given Miranda warnings until after Fries had taken and typed a statement from him. Defendant agreed that at that latter point he was given the warnings, initialed a form containing a rights advisement, and executed a written waiver.
After hearing the above-summarized testimony, the trial court suppressed the statement made by the defendant to Officer Fries concerning the forgery and theft charges. 1 The court found that the defendant had a right to an expectation of privacy in the factory, that there was not probable cause for the police entry, that the subsequent arrest and search were illegal, and that the statement in question was the result of an illegal arrest. The court also found that there were no exigent circumstances shown to avoid the search warrant requirements.
Three issues are raised by this appeal: (1) whether defendant had standing to contest the police entry onto his employer’s premise, (2) whether the police acted illegally in entering the factory without a warrant, and (3) whether the defendant’s statements to the police should be considered “the fruit of the poisonous tree.”
I.
It has long been recognized that fourth amendment rights are personal and may not be asserted vicariously. Traditional concepts of standing were phrased in terms of requirements that the moving party have a proprietary or possessory interest in the premises searched (Brown v. United States (1973),
In the case at bar, the State points out that defendant was a part-time employee who worked at the grinding company on a consignment basis. Moreover, the door to the grinding company was unlocked at the time the police made their entry. The State contends that a person in such a situation could not have had a legitimate expectation of privacy in the premises and may therefore not challenge a police entry. However, Mancusi v. DeForte made clear that a person may have an expectation of privacy in an area where he works. Mancusi involved the search of an office, consisting of one large room, which the defendant shared with several other union officials. Although the defendant shared the premises with others and it was not claimed that the items seized were taken from an area reserved exclusively for his personal use, the court took the view that he nonetheless could have reasonably expected that only his coworkers and their guests would enter the office, and that only persons authorized by the union would go through the items contained therein. In the instant case, as was true in Mancusi, the business premises entered consisted of a large open area not reserved exclusively for any given employee. Rakas and Mancusi confer a right to raise a fourth amendment challenge where there was a reasonable expectation of privacy against governmental intrusion. Thus, the fact that defendant might have expected co-workers to enter the building does not deprive him of a basis to challenge a police entry. A different result might follow if entry into the premises had been so commonplace or inevitable that defendant must necessarily have expected to be observed by certain third persons or by members of the public in general. (See People v. Heflin (1976),
II.
Having concluded that the defendant had standing, we now turn to the merits of the issues raised by the defendant’s assertion that his fourth amendment rights were violated. The State first argues that under our holding in People v. Lerch (1966),
Having disposed of the State’s initial contentions, we conclude that to be lawful the detectives’ entry into the grinding company had to be based on probable cause and sufficient exigent circumstances to excuse their obtaining a warrant. (People v. Grant (1974),
The State asserts that the second prong of the Aguilar test was satisfied because the information provided was obtained from a citizen informant. Citing People v. Hoffman (1970),
Moreover, there were no exigent circumstances in this case which would justify the detectives’ entry into the grinding company without a warrant. In Vale v. Louisiana (1970),
III.
The final issue is whether in light of the illegality of the initial entry, the subsequent statements to the police were properly suppressed as the “fruit of the poisonous tree.” (Wong Sun v. United States (1963),
The most recent expression of our supreme court on this issue is People v. Gabbard (1979),
The most significant difference between the instant case and Gabbard involves the key factor of intervening circumstances. In Gabbard the court specifically found that the defendant’s statements were prompted by the intervening events of being shown a composite sketch of the suspect and being identified in a lineup. (
The final distinguishing factor between Gabbard and the instant case involves the standard of review. A suppression order will only be reversed if the trial court’s ruling was manifestly erroneous. (People v. Van Note (1978),
