Appellant was indicted for and convicted of first degree homicide by vehicle (OCGA § 40-6-393); driving under the influence of alcohol (OCGA § 40-6-391); failure to render aid (OCGA § 40-6-271); and operating a vehicle without insurance (OCGA § 33-34-12). In this appeal, he questions the omission of two requested instructions from the trial court’s jury charge and the admissibility of certain expert testimony.
1. Appellant submitted a written request to the trial court that it charge the jury that “upon the trial of a criminal case the jury is the judge of both the law and the facts.” The trial court did not honor appellant’s request verbatim; instead, it chose to instruct the jury that “it is the duty and responsibility of the judge to ascertain the law applicable to a case and to instruct [the jury] of what the law consists. It is [the jury’s] duty and responsibility to ascertain the truth of the case from a factual standpoint from the evidence presented to [the jury]. Then it is [the jury’s] duty and responsibility to apply the law to the facts, and by this application of law to fact and of fact to law, arrive at a verdict in this case.” Appellant argues that reversible error was committed when his charge which was taken from OCGA § 17-9-2 was not given as requested.
“It is not reversible error to fail to charge in the exact language requested when the charge given adequately covers the correct legal principles. [Cits.]”
Mullins v. State,
2. The trial court also failed to give appellant’s requested instruction that “in a criminal case, there is no inference to be drawn from a failure to produce evidence by either side.” This requested charge was submitted to the trial court subsequent to and in response to the district attorney’s closing argument in which he pointed out to the jury the failure of the defense to produce several potential defense witnesses. Appellant asserts that the trial court’s refusal to give the requested instruction allowed the State to create an inference of guilt from appellant’s failure to produce the “missing” evidence.
The closing argument of the district attorney was not improper.
Wilson v. Zant,
3. Lastly, appellant contends that the testimony of a forensic chemist concerning blood alcohol content level (BAC) was improperly admitted because it was without foundation. Appellant argues that the testimony was in response to a hypothetical question which was based upon facts not in evidence.
The multi-vehicle collision which is the basis for the criminal charges brought against appellant occurred at approximately 9:40 p.m. Appellant was not located and his blood-alcohol content not tested until 12:08 a.m., at which time his BAC registered .09 grams of alcohol per 100 milligrams of blood. Using this information and various metabolic rates for men of appellant’s approximate weight, the *210 expert witness testified to a range of projected BAC’s which might have resulted had appellant been tested at 9:40 p.m. The range stretched from .115 to .14 grams of alcohol per 100 milligrams of blood.
Appellant complains that the expert’s testimony was inadmissible because there was no evidence of appellant’s metabolic rate and no evidence that appellant had not consumed any food or alcoholic beverages during the
2-Vz
-hour period between the accident and the blood-alcohol content test. “Although the question was phrased in part as a hypothetical question, in fact it asked the witness to give his opinion based on his observations [of appellant’s weight]. A hypothetical question is not required where a properly qualified expert testifies as to his opinion based on facts within his personal knowledge. [Cit.]”
Ware v. State,
Judgment affirmed.
