The defendant moved to suppress on grounds that an officer stopped him without reasonable suspicion. At a hearing on the suppression motion, the State stipulated that the officer knew, at the time of the stop, that the robbery suspects the officer was looking for were approximately 18 years old. The defendant was 51 years old. However, at the hearing, the officer gave testimony contradicting this stipulation and indicating that he did not learn of the suspects’ age until after he had arrested the defendant. The court concluded that the stipulation was binding on the State, even though the defendant made no objection when the officer testified.
