State v. Turner

Summary

The court affirmed the conviction, holding that the defendant was not entitled to review of his unpreserved challenge to cell-phone mapping evidence under the constitutional-review doctrine, plain-error doctrine, or supervisory authority. The trial court was not required to conduct a scientific-evidence hearing sua sponte, and the undeveloped record did not establish that the evidence was improperly admitted or materially affected the trial. The court also declined to adopt a plain-error standard measured by the law existing at the time of appellate review.
