analogous to F.S. Section 933.09, F.S.A. 1971, the statute now before this court. The only significant difference between the two statutes is that the former governs official entries for the purpose of effecting an arrest while the latter governs official entries for the purpose of executing a search warrant. Benefield v. State, supra, is, therefore, persuasive authority for the construction of F.S. Section 933.09, F.S.A. 1971.
In the present case, the evidence clearly revealed that the officers did not comply with the controlling statute in that before entry they did neither knock nor otherwise announce their presence to the Colliers within nor did they announce their purpose. As a result of the failure of the officers to comply with the statute, the evidence seized under the warrant was seized illegally, was not admissible in evidence, and was, therefore, subject to suppression. Benefield v. State, supra; McLendon v. State, Fla.App.1965, 176 So.2d 568, and Weiner v. Kelly, Fla.1955, 82 So.2d 155 (dictum).
The state contends that the statute need not be followed where persons within the residence are already aware of the authority and purpose of the officers or where compliance would afford an opportunity to those within the premises to destroy the incriminating items sought by the investigating officers. With regard to the first exception relied on by the state, we simply note that there was no evidence to indicate that the Colliers, the appellees here, were aware of the authority and purpose of the officers prior to their entry. With regard to the second exception relied on by the state, we agree that non-compliance with the statute may not necessarily result in the exclusion of the seized evidence where the officers involved have a reasonable ground to believe compliance with the statute would result in destruction of the evidence before the search and seizure could be effected. See Benefield v. State, supra. Where, however, non-compliance is shown and the state wishes to justify the same on the basis of such exception, it is incumbent upon the state to produce evidence to support same. See Earman v. State, Florida Supreme Court, 265 So.2d 695, opinion filed August 2, 1972.
In the present case the state did not present evidence to show that the investigating officers were in fact concerned or had reasonable grounds to be concerned about the destruction of evidence. The state did not even produce evidence at the suppression hearing as to the disposable nature of the items expected to be revealed by the search, even though Officer Hill has been in the premises prior to the time the search was conducted. Officer Hill did testify that when he was in the residence before the search occurred, he observed what he thought was a pot party in progress. This rather vague testimony does not provide a basis for an inference that the officers had a reasonable ground to fear the destruction of evidence. At least it was not such conclusive evidence on this issue that we can hold the trial judge in error for failing to find the existence of such exceptional circumstances that would justify non-compliance with the statute.
At oral argument the state contended that because Officer Hill was invited into the apartment as a social guest, he had the right, after leaving and without further formality, to re-enter the apartment with his fellow officers for purposes of executing the search warrant. This argument really begs the question because it assumes, without demonstrating, that the statute in question has an exception which covers such an entry. The statute does not have such exception and one cannot reasonably be found in the implication of the statute. It seems rather clear that Officer Hill’s first entry into the apartment was authorized by the Colliers, but that such authorization did not relieve Officer Hill from the burdens of the statute after he left and
