In prosecution on unlawful possession of firearm charge, Dist. Ct. did not err in denying defendant’s motion to suppress warrantless seizure of firearm initially discovered by Cook County Dept. of Revenue agents, who had entered defendant’s convenience store to investigate recent purchase of cigarettes that failed to contain proper tax stamps. Record showed that agents found firearm in area of store where cigarettes were stored and in area near jar that contained likely narcotics that store sold for $5 per pill, and Ct. rejected defendant’s challenge to local cigarette ordinance that allowed agents to make instant administrative search. Also, Ct. found that instant warrantless search of defendant’s store was not unreasonable under Burger, 482 U.S. 691, since defendant did not possess reasonable expectation of privacy in view of ordinance that gave defendant notice of potential for instant search, as well as fact that sale of cigarettes was pervasively regulated business.
