7th Circuit Court of Appeals
Case Name: United States of America v. Ronald Tingle
Case No.: 17-1604
Officials: BAUER, KANNE, and ROVNER, Circuit Judges.
Focus: Sufficiency of Evidence – Expert Testimony
Ronald Tingle was tried and convicted of possessing and distributing methamphetamine and of possessing a firearm in furtherance of a drug trafficking crime. On appeal, he argues that the district court erred when it allowed a government witness to give expert testimony without properly vetting the witness’s credentials and when it allowed the same witness to testify regarding the defendant’s mental state. Additionally, Tingle argues that he should have been granted access to grand jury materials and that his case should have been dismissed based on prosecutorial vindictiveness. For the reasons that follow, each of these claims fails, and the judgment of the district court is affirmed.
