Must police disclose prior illegal entries when seeking search warrants? State v. Krukowski Explained

The Utah Supreme Court in State v. Krukowski addressed a critical question about police disclosure obligations when seeking search warrants following prior illegal entries. The case establishes important boundaries for warrant applications and the independent source doctrine.

Background and Facts

Detective McNaughton received information that Randy Krukowski was manufacturing methamphetamine in a storage unit. At the facility, McNaughton observed Krukowski’s truck and an ajar door. After a drug dog alerted, McNaughton requested entry but Krukowski refused. McNaughton and another officer nevertheless entered illegally and observed a methamphetamine lab. McNaughton then sought a search warrant, but his affidavit did not disclose the prior illegal entry. The magistrate issued the warrant based on the pre-entry observations and informant information.

Key Legal Issues

The central issue was whether police officers must disclose prior illegal entries to magistrates when seeking search warrants. Krukowski argued under Franks v. Delaware that the omission was material to the probable cause determination. The State countered that the subsequent warranted search was valid under the independent source doctrine from Murray v. United States.

Court’s Analysis and Holding

The Utah Supreme Court reversed, holding that officers need not disclose prior illegal entries when seeking warrants because such information is not material to probable cause. The Court distinguished between the “normal burden” of establishing probable cause before a magistrate and the “much more onerous burden” of proving the independent source doctrine in suppression proceedings. The Court noted that disclosure could actually prejudice the magistrate’s assessment by signaling that incriminating evidence had already been found.

Practice Implications

This decision clarifies that Murray‘s independent source analysis occurs at the suppression hearing, not during warrant applications. Prosecutors should focus on establishing that probable cause existed independently of any illegal entry. Defense counsel should examine whether officers actually relied on illegally obtained information when seeking warrants, even if not explicitly disclosed. The ruling also affects credibility assessments—failure to disclose prior entries cannot alone support adverse credibility findings.
