United States v. Montgomery, No. 17-1969 (8th Cir. 2018)Annotate this Case
The Eighth Circuit affirmed the district court's revocation of supervised release after finding that defendant violated many conditions, including the use of controlled substances. The court held that the district court did not abuse its discretion when it admitted transcripts of an expert witness from two prior Northern Iowa cases where the expert testified in detail about the reliability and acceptance of sweat patch testing was harmless. The evidence was cumulative and unnecessary in light of the other evidence in the case.
