DaytonDUI, Defending a Breath Test Case

January 26th, 2012
Big Bad Wolf

“I’ll Huff and I’ll Puff and Blow Your House Down”

Did you know that your breathing pattern can significantly alter the concentration of alcohol on your evidential breath test?  According to scientific research, “[t]he subject’s test manner of breathing just prior to providing breath for analysis can significantly alter the concentration of alcohol in the resulting exhalation.” (Jones, 1982, Schoknecht, 1989) as cited in Physiological Aspecs of Breath-Alcohol Measurement, Alcohol Drugs & Driving Vol. 6, No. 2, A.W. Jones.

Hyperventilation “…lowers the breath alcohol concentration by as much as 20% compared with a single moderate inhalation and forced exhalation used as control tests.” Id. (Jones, 1982).  Whereas, “holding breath for a short time (20 seconds) before exhalation increases the alcohol concentration in exhaled air by 15%. Id. (Jones, 1982).

With Ohio’s adoption of the Intoxilyzer 8000 breath test machine, attorneys should be on the look out for these types of breathing pattern defenses.  Tell your Ohio DUI lawyer if you were asked to hold your breath, blow in an unusual pattern or if the officer abruptly told you to stop blowing.  Your attorney needs to know how you blew because an operator may be looking to manipulate your breath pattern to force agreement of a first blow and  a second blow.

Charles M. Rowland II, DaytonDUI, is certified on the Intoxilyzer 8000 and has attended training on the machine wherein defenses like the breathing pattern defense and the long-blow breath test defense are explained in scientific detail.  He has been a city prosecutor and is Ohio’s only Forensic Sobriety Assessment certified attorney.  If you need to fight your DUI, contact attorney Charles M. Rowland II at 937-318-1DUI or 888-ROWLAND. “All I do is DUI Defense.”

Forensic Blood Tests: Whole Blood vs. Serum/Plasma

January 10th, 2012

English: Bags of blood collected during donati...Ohio Administrative Code 3701-53-03(A) sets forth the techniques and methods for determining the concentration of alcohol in blood, urine and other bodily substances.  Pursuant to that rule, Ohio allows for testing including gas chromatography and enzyme assays.  To challenge a blood test, it is important to know if the State has tested the blood as whole blood or as serum/plasma.  Operation with a concentration of alcohol is prohibited if the concentration in whole blood is equal to or exceeds .08%, R.C. 4511.19(A)(1)(b).  However, the prohibited concentration for whole blood is a concentration equal to or exceeding .096%, R.C.4511.19(A)(1)(c).  The high teir (super-OVI) standard for whole blood is greater than .17% and the prohibited level for blood serum or plasma is greater than .204%.  If your attorney does not understand the difference between a whole blood and a serum/plasma test, he or she may give incorrect advise based on an incorrect assumption.  Secondly, studies suggest that plasma and serum tests can be 16 to 21 percent higher than whole blood tests (Taylor, 2000; Fitzgerald, 1999).  If the report that you receive from the Crime Lab does not specify whether whole blood or serum was tested, consider making a request for independent testing of the sample.

The Ohio rules for collection of blood specimens are set forth at Ohio Administrative Code 3701-53-05.  In State v. Meyers, 146 Ohio App.3d 563, 2001-Ohio-2282 (3d Dist. Allen County 2001), the court allowed the state to use a blood tests that were taken for diagnostic and treatment purposes so long as the tests are in compliance with the OAC regulations.  In State v. Gordon, 2002-Ohio-2140 (Ohio Ct. App. 8th Dist Cuyahoga County 2002) the Eight District Court of Appeals upheld the suppression of a blood draw when the State’s toxicologist did not testify regarding the conversion of the serum alcohol content to a whole blood concentration, nor did the toxicologist testify as to any laboratory procedures for testing blood serum content and converting the results to that of whole blood. See Weiler & Weiler, Ohio Driving Under the Influence, pp. 195-201.

Blood Contamination & Candida Albicans

December 27th, 2011
Feeling Faint

If a blood sample is not properly preserved it can decompose.  One of the results of decomposition is the creation of alcohol.  According to Lawrence Taylor in his seminal Drunk Driving Defense, 6th Ed., pp. 561, “Ethyl alcohol is generated by fermentation of carbohydrates and proteins in the blood sample.  This occurs through the actions of various microorganisms.  The simplest and one of the most common processes is the breakdown of enzymes by one of various species of the yeast Candida, such as Candida albicans.”  The results of the fermentation in the blood vial is dramatic.  For example, a blood sample which contains no alcohol can decompose and cause a reading of .25 percent or even higher, depending on the stage of decay. (See Taylor, Id. at 561).

Proper handling of the blood sample requires the refrigeration of the blood sample.  The problem is that refrigeration can only slow down the decomposition process not end it completely.  Another protective measure is the addition of a preservative, such as sodium fluoride.  Scientific studies (as cited in Taylor, Id. at 563) suggest that sodium fluoride can be ineffective in preventing alcohol production by Candida albicans.  Counsel should also be aware of common human errors which can occur following collection of the blood sample.  It is not at all uncommon for the blood to be collected and the vial not inverted to allow the mixing of the preservative and the sample.  Make sure that your DUI defense attorney is aware of these problems which may prevent the introduction of your blood test, or provide you with a viable defense in your case.

Aggravated Vehicular Homicide, O.R.C. 2903.06

December 19th, 2011

Aggravated Vehicular Homicide, O.R.C. 2903.06,  is a crime that results from the death of another caused by the defendant’s operating a vehicle while impaired (a violation of R.C. 4511.19)  or while driving negligently or recklessly.  The statute  encompasses driving an automobile recklessly or negligently (called Vehicular homicide) whether or not alcohol played a part in the death.  Often, defendants are indicted for multiple counts, with additional counts for each victim of the accident.

Under the reckless section of the statute you will be found guilty of a third degree felony which rises to a second degree felony if the driver is under suspension at the time of the offense.  Aggravated vehicular homicide when impaired as defined in R.C. 4511.19 is a second degree felony which rises to a first degree felony if the driver was under suspension at the time of the offense. Penalties include mandatory prison terms with a penalty of up to 10 years in prison and a $20,000 fine for the 1st degree felony and prison up to 8 years and a fine up to $15,000 for the 2nd degree felony.

If drunk driving (now called OVI; operating a vehicle while impaired)  has been charged as the proximate cause of the death, the penalties become mandatory and are very difficult to get reduced or lowered.  Often, these cases are high-profile cases engendering much prejudice toward the defendant.  This  is the time to hire someone who has been successful in trying aggravated vehicular homicide cases.  Call Charles Rowland at 937-318-1DUI (318-1384).

If you’ve been arrested on charges of aggravated vehicular homicide, it’s essential to talk to an attorney about your case before talking to investigators. Charles Rowland has represented felony defendants in Dayton and throughout the Miami Valley.  To schedule a confidential consultation to discuss your case contact Charles Rowland at 937-318-1DUI (318-1384).  Charles Rowland, “All I Do is DUI defense.“

DUI Science and More Faulty Breath Machine Assumptions

December 8th, 2011

Evidential Breath Testing Measures The Amount of Alcohol In Your Breath Not in Your Brain!

A chimpanzee brain at the Science Museum London

One of the faulty assumptions underlying evidential breath testing is the assumption that the tests are measuring the ability of alcohol to impair your brain.  They do not.  The breath test does not care how, or even if, the alcohol is impairing your brain only that it is in your breath via your lungs via your blood.  The machines do not test venous blood but arterial blood utilizing the scientific principle of Henry’s Law.  As alcohol can be at different rates throughout your body, the machine is not measuring impairment.

During peak absorption arterial blood is higher than  venous blood.  Arterial blood travels to the lungs for normal bodily air exchange and comes into contact with the highest level of alcohol concentration thereby resulting in an overstated (disproportionately high) BAC level.  Venous blood  more accurately indicates BAC levels inside the tissues of the brain and is a better indicator of how much the alcohol is impairing your brain function.

When you start looking closely at the built-in assumptions underlying the tests, you begin to see that evidential breath testing is not the whole truth and nothing but the truth.  Like any other evidence offered in the courtroom it should be vigorously cross-examined just like any other witness against you.
