Background
On August 7, 2021, Jonathan Andrew Berretta drove his vehicle in the oncoming lane of Highway 55 near Tullahoma, causing a head-on collision with Katie Leigh Bauer, who died from her injuries. Berretta admitted to consuming 12–16 beers throughout the day before driving. Emergency responders detected a strong odor of alcohol and transported him to Vanderbilt University Medical Center (VUMC) by helicopter.
Before transport, a Tullahoma Police sergeant directed EMS to conduct a warrantless blood draw, citing exigent circumstances and probable cause based on the wrong-lane driving, fatal collision, and observed odor of alcohol. At VUMC, a second blood draw was obtained pursuant to a search warrant. Three VUMC samples tested positive for blood alcohol concentrations of 0.283, 0.296, and 0.214—all well above Tennessee’s per se limit.
The jury convicted Berretta of vehicular homicide by intoxication and vehicular homicide per se. He received a 12-year sentence, to run consecutively to a pending Davidson County sentence. Berretta appealed on thirteen grounds, challenging the admission of blood evidence, trial procedures, and sentencing.
The Court’s Holding
The Court of Criminal Appeals affirmed the conviction and sentence in full. On the suppression issues, the court held that exigent circumstances justified the initial warrantless blood draw: the officer reasonably believed obtaining a warrant—requiring travel to draft it, secure a judicial commissioner’s signature, and return to the hospital—would consume at least an hour and fifteen minutes before the defendant’s helicopter transport. The officer had probable cause based on the defendant’s wrong-lane driving, the fatal head-on collision, and the strong odor of alcohol reported by paramedics and EMTs.
Regarding the VUMC warrant, the court rejected the defendant’s argument that the affidavit contained false or recklessly made statements. The paramedics who worked directly on the defendant in the ambulance reported a strong odor of alcohol; the sergeant’s failure to personally smell alcohol did not contradict this, since he had no direct contact with the defendant. Even excluding the odor allegation entirely, probable cause existed based on the wrong-lane fatal collision and the officer’s expert opinion that intoxication likely caused the crash. The court applied a commonsense, nonhypertechnical reading of the affidavit consistent with Fourth Amendment precedent.
Key Takeaways
- Exigent circumstances can justify a warrantless blood draw when the officer reasonably believes the warrant process cannot be completed before the suspect is transported away.
- In DUI cases, probable cause does not require field sobriety tests, visible signs of impairment, or an admission to drinking; the totality of circumstances—including driving behavior, crash characteristics, and evidence of alcohol—may suffice.
- Wrong-lane driving resulting in a fatal head-on collision, combined with the odor of alcohol, provides substantial probable cause for a blood-draw warrant.
- When applying warrant affidavits, courts must use a commonsense, nonhypertechnical approach rather than parsing language with strict construction.
Why It Matters
This decision provides important guidance on the intersection of exigent circumstances and the warrant requirement in drunk-driving cases. Law enforcement can rely on the practical constraints of obtaining a warrant in high-speed transport scenarios (e.g., helicopter evacuation) to justify immediate blood draws without prior judicial approval. The court’s affirmation that wrong-lane fatal collisions combined with alcohol evidence establish probable cause reflects a practical recognition that certain driving behaviors are inherently probative of intoxication.
The court’s rejection of hypertechnical parsing also clarifies that courts reviewing warrant affidavits need not adopt unreasonable interpretations—here, the statement that paramedics reported an odor was read consistently with the facts that the paramedics communicated this information to the officer by phone the next day, not necessarily at the scene. This commonsense approach may influence similar evidentiary disputes in criminal cases across Tennessee.
