Blood Draw of Unconscious DUI Suspect at Hospital does not Automatically Excuse Warrant Requirement
People v. Castro (Cal. Ct. App., July 1, 2026, No. D085983) 2026 WL 1894067, at *1–3
Summary: The United States Supreme Court Mitchell v. Wisconsin (2019) 588 U.S. 840 (Mitchell), held that where a police officer at the scene of an automobile accident discovers that one of the drivers suspected of driving under the influence of alcohol (DUI) is unconscious,“the officers’ many responsibilities may be incompatible with the procedures that would be required to obtain a warrant.” Mitchell articulated a “general rule” that exigent circumstances will “almost always” permit a blood test without a warrant.
In People v. Alvarez (2023) 98 Cal.App.5th 531 (Alvarez), the police officer encountered the suspect-driver at the hospital sometime after the accident. Alvarez held that the record failed to support a finding of exigency sufficient to excuse the officer’s failure to obtain a blood draw warrant. Here, an unconscious suspect-driver was first contacted by police at the hospital several hours after the accident, and the Court held there was not exigent circumstances excusing a failure to obtain a warrant.
