State v. ClarkState v. Clark
Frank Clark appeals his conviction on one count of vehicular homicide,
Facts
On December 21, 1988, Frank Clark was charged by information with one count of vehicular homicide under
Within a half-hour of the accident, at 12:30 a.m. on February 15, a sample of Clark's blood was drawn as a part of the accident investigation. On February 16, Glen Case, a forensic toxicologist employed with the state toxicology lab, received two vacutainers 1 containing Clark's blood sample. Case performed two tests on one of the tubes on February 16, 1988, and analyzed the other tube on July 25, 1989; both tests were for the presence of ethyl alcohol concentration. The testing method used was gas chromatography.
Case testified that the vacutainers, as supplied by the manufacturer, contained two chemicals: sodium fluoride and potassium oxalate. Case stated that potassium oxalate is an anticoagulant, or a substance that maintains the sample as whole blood, thus preventing it from dividing into plasma and red blood cells. Sodium fluoride, Case testified, is both an anticoagulant and an antienzymatic compound that prevents enzyme activity on blood samples.
Case acknowledged that the state toxicology lab did not independently verify the chemicals contained in the vacu-tainers received from the manufacturer. When shown a letter from the manufacturer detailing the amount of sodium fluoride and potassium oxalate put in the vacu-tainers, Case stated that the amounts shown would be sufficient to prevent coagulation and preserve the alcohol in a sample that was drawn more than 30 days before testing. Case stated that, in his experience, a blood sample that contained neither an anticoagulant nor an enzymatic poison could be analyzed for up to 30 days without a change in alcohol concentration. When an anticoagulant and enzyme poison were contained in the sample, Case's studies indicated that a sample containing
Clark moved to suppress the blood test results on two grounds. First, Clark argued that under
The trial court denied Clark's motion to suppress, entering findings of fact and conclusions of law. Clark has assigned error to the following factual findings:
4. WAC describes the criteria to be any test which meets the standards that the state toxicologist sets for himself.
5. The toxicologist has accepted Gas Chromatography as [a] test.
6. The Toxicologist has detailed standards.
7. The Gas Chromatography test does meet all the standards set by the Toxicologist.
8. The methods refereed [sic] to by RCW include a description of the nature of the test and the expectation that the legislature would have for those tests. This has been complied with.
9. The intent of
10.
11. In this particular case a sufficient amount of anticoagulant and enzyme poison to comply with
12. The consistency of the two tests administered on the blood sample and the letters form [sic] [the manufacturer] satisfy the court that there were sufficient amounts of anticoagulant and enzyme poison in the vacutainer vial.
Approval of Testing Methods
Clark first argues that, although mandated to do so by
Under
Analysis of the person's blood or breath to be considered valid under the provisions of this section orRCW 46.61.502 or 46.61.504 shall have been performed according to methods approved by the state toxicologist and by an individual possessing a valid permit issued by the state toxicologist for this purpose. The state toxicologist is directed to approve satisfactory techniques or methods ....

Any quantitative blood alcohol analysis method which meets the following criteria is approved by the state toxicologist and may be used in the state of Washington. Analysis of urine for estimation of blood alcohol concentrations is not approved by the state toxicologist in the state of Washington.
The blood analysis procedure should have the following capabilities:
(1) Precision and accuracy.
(b)
Except for gas chromatography,
the method should be calibrated with water solutions of ethyl alcohol, the strength

The WAC does not contain regulations detailing approved testing methods, but rather, outlines the
criteria
any approved method must meet.
See
The regulations approve the tests only if they meet strict standards for precision, accuracy, and specificity.WAC 448-14-010. The regulations also specify the general manner in which tests must be conducted.WAC 448-14-010. WAC 448-14-020 sets forth analytical and reporting procedures for blood tests, and standards for sample containers and preservation.WAC 448-14-030 sets forth qualifications for blood alcohol analysts.
Schulze,
at 167. Stating that a "cookbook detailing" of every step of the authorized procedure was not necessary, the court held that regulations set out in
In this case, Clark contends that
The court in
Schulze
explicitly held that
The next question is whether substantial evidence supports the trial court's conclusion that the state toxicologist has approved of gas chromatography as a testing method. Glen Case testified that in his 17 years in the field of toxicology, he had tested nearly 20,000 blood samples for the presence of alcohol. He stated that the gas chromatography method was employed in "[b]asically all" of the tests. Case also testified that his office had a written protocol detailing the methods used for performing gas chromatography tests, and that it was "the method we use, . . .". Gas chromatography is the only testing method specifically mentioned in
Before blood alcohol test results can be admitted into evidence, the State must present prima facie proof that the test chemicals and the blood sample are free from any adulteration which could conceivably introduce error to the test results.
State v. Weston,
Blood samples for alcohol analysis shall be preserved with an anticoagulant and an enzyme poison sufficient in amount to prevent clotting and stabilize the alcohol concentration. Suitable preservatives and anticoagulants include the combination of sodium fluoride and potassium oxalate.
Clark has assigned error to the trial court's finding that, in this particular case, "a sufficient amount of anticoagulant and enzyme poison to comply with
We agree with the trial court's determination. The obvious purpose of
On the basis of similar evidence, this court in
State v. Barefield, supra,
held that a proper foundation had been established for admitting a vial of blood into evidence. The state toxicologist in
Barefield
testified that the sample was not adulterated and that the vial manufacturer always put an anticoagulant in vials of that type.
Barefield,
at 458. The court also relied on company literature and the labeling on the vial, both of which indicated the presence of an anticoagulant.
Barefield,
at 458.
See also State v. Steinbrunn,
The State in this case made a prima facie showing that Clark's blood sample was properly preserved. This being accomplished, it was for the trier of fact to determine the weight to attach to the evidence. Steinbrunn, at 513.
Coleman and Agid, JJ., concur.
Notes
A "vacutainer" is a glass tube sealed with a stopper so that it is "under vacuum", or capable of drawing fluid directly through a needle once the stopper is pierced with the needle.
Clark relies on cases from other jurisdictions which, on the basis of statutes similar to
Gas chromatography was the testing method used in
State v. Curran,
Regarding the use of preservatives in blood samples, Case's testimony is consistent with that given by state toxicologists in other cases.
See State v. Barefield, supra
at 458 (state toxicologist testified that presence or absence of an anticoagulant would not affect test results);
State v. Steinbrunn,
The consistency of blood test results is particularly significant. As Case testified, a constant level of alcohol concentration in a blood sample can only be maintained for 30 days where no preservatives are used. Although the two tests here were administered nearly 1 1/2 years apart, the results were the same. This gives rise to a strong inference that the vacutainers contained an anticoagulant and enzyme poison.
