Young v. StateAnnotate this Case
After a jury trial, Defendant was convicted of driving under the influence of alcohol. During the trial, the district court allowed the State to introduce expert testimony involving retrograde extrapolation to prove that Defendant’s blood alcohol level was above the legal limit of 0.08 percent while he was driving on the night in question. Defendant did not object to the admission of the testimony at trial. On appeal, Defendant challenged the admission of the retrograde extrapolation evidence. The Supreme Court affirmed, holding that Defendant failed to establish that he was prejudiced by admission of the challenged evidence.
