In the realm of DWI defense, there’s a peculiar term that often surfaces during stops and subsequent arrests: the “unknown odor of an alcoholic beverage.” This phrase is frequently cited by officers in their reports, but what does it really mean, and how does it affect your DWI case?
First, it’s essential to understand that the “odor of alcohol” is somewhat of a misnomer. Pure alcohol has no smell. The familiar scent associated with alcoholic beverages comes from the flavoring substances that are added. Therefore, when an officer claims to detect an “unknown odor of an alcoholic beverage,” it’s a subjective observation that’s open to scrutiny.
The Subjectivity of Sensory Observations
An officer’s sensory observation is not an objective measure like a breathalyzer test. It’s influenced by numerous factors, including the officer’s experience, expectations, and even potential biases. In the context of a traffic stop, this subjective observation can be challenged on several grounds.Cross-Examination of Observations
At Zendeh Del & Associates, PLLC, we understand the nuances of these sensory claims and how to confront them effectively. During cross-examination, we question the officer’s basis for comparison. How can one identify an “unknown” odor? How many types of alcoholic beverages can the officer distinguish by smell alone? These are critical questions that often reveal the shaky foundation upon which these observations stand.Scientific Evidence and Expert Testimony
We also employ scientific evidence and expert testimony to counter the claims of an “unknown odor.” Experts can explain to the jury the complexities of olfactory perception and how unreliable it can be. The supposed detection of an alcoholic odor does not quantify impairment or consumption, which are the crux of a DWI charge.Common Misidentifications
Several everyday items and substances can produce odors mistaken for alcoholic beverages. For instance:- Mouthwash and Dental Hygiene Products: Many of these contain alcohol, which can leave a misleading scent.
- Certain Foods and Drinks: Foods cooked with or containing alcohol, like vanilla extract in desserts or sauces with wine, can emit a similar smell.
- Medications and Health Products: Cough syrups and herbal remedies often have high alcohol content and can be misconstrued as evidence of drinking.
- Industrial and Cleaning Products: Cleaners, disinfectants, and solvents sometimes contain forms of alcohol that can be mistaken for the beverage type.
- Diabetics: Individuals with diabetes can sometimes exhibit breath that smells fruity or similar to an alcoholic beverage, a phenomenon that can be misleading during a DWI investigation. This distinctive odor is due to the presence of ketones in the breath, particularly acetone, which is produced when the body starts burning fat for energy instead of glucose—a process that occurs when insulin levels are insufficient to metabolize blood sugar effectively. This condition, known as ketoacidosis, can be exacerbated by factors such as missed insulin treatments or not eating enough. The similarity between the smell of ketones and certain alcoholic beverages arises because some drinks also contain fruity or sweet compounds, leading to potential confusion. Understanding this medical reality is crucial in DWI defense, as it highlights the importance of not jumping to conclusions based solely on the smell of a person’s breath.
