Whether the warrantless search of the trunk of Dombrowski's disabled, towed, and unguarded Thunderbird was unreasonable under the Fourth and Fourteenth Amendments.
Holding
No. The trunk search was a reasonable community-caretaking search to locate a revolver that officers reasonably believed might endanger the public.
Reasoning
The Fourth Amendment's ultimate standard is reasonableness. Although warrantless searches of private property generally are unreasonable unless an established exception applies, automobiles are constitutionally different from homes. Their mobility and the extensive, routine, noncriminal contact between police and vehicles make some warrantless vehicle searches reasonable in circumstances where a comparable home search would not be.
The officers had lawfully exercised control over the Thunderbird after the accident. Dombrowski was intoxicated and then hospitalized, so he could not arrange for the disabled vehicle. The police had it towed from the highway to a private garage, where it remained outside and unguarded rather than in secure police custody.
State courts and the federal district court found that Officer Weiss searched for the revolver pursuant to standard departmental practice, not as a pretext to investigate crime. The Seventh Circuit could independently decide the constitutional question, but it could not disregard those supported factual findings. At the time of the search, Weiss did not know that a murder or any other serious crime had occurred.
Preston did not control because Preston held only that a remote automobile search could not be justified as incident to an arrest. The State did not rely on an arrest-incident rationale here. Harris and Cooper instead demonstrated that lawful police control over a vehicle can justify limited warrantless intrusions connected to caretaking and custody.
The officers reasonably feared that a gun in the car's locked trunk could be taken by vandals or other unauthorized persons from the unguarded lot. That public-safety concern was immediate and constitutionally reasonable. The possibility that police might have used a less intrusive measure, such as posting a guard, did not itself make the search unreasonable, particularly in the rural setting involved.
