Background

A jury convicted Alexzandra Blanco of two conspiracies with her romantic partner, Tremain Monroe, to distribute fentanyl. The first arose from a March 2023 incident in which Monroe handed fentanyl pills to Blanco, Blanco crushed them, and Blanco gave Mathisen Boldt a rolled-up dollar bill to ingest the powder. Boldt overdosed, required emergency medical treatment, and later became a confidential informant.

Boldt subsequently completed three controlled fentanyl purchases involving Monroe and Blanco. During a search of the couple’s residence, officers found fentanyl pills, prescription bottles, naloxone, laxatives, cash, and approximately five pounds of methamphetamine. The district court sentenced Blanco to the statutory minimum of 240 months, below the advisory Guidelines range of 262 to 327 months.

The Court’s Holding

The Eighth Circuit affirmed. It held that the district court did not abuse its discretion by admitting evidence of unlabeled prescription bottles because the bottles were relevant to possible drug possession and to the overall condition of the room where evidence was seized, and their probative value was not substantially outweighed by unfair prejudice. The court also upheld Boldt’s testimony about Blanco receiving drug-related text messages, concluding that Boldt had sufficient personal knowledge and that the testimony reasonably concerned Blanco’s admissions or Monroe’s statements made in furtherance of the conspiracy.

The court further held that evidence of the nearby methamphetamine was admissible as res gestae evidence completing the story of the investigation and was not unfairly prejudicial. Alternatively, any evidentiary error was harmless given the government’s ample evidence. Finally, the evidence was sufficient for a reasonable jury to find that Blanco knowingly joined both conspiracies and that the March distribution caused Boldt’s serious bodily injury.

Key Takeaways

  • Unlabeled pill bottles found in a shared bedroom were relevant to fentanyl-possession and distribution charges and were not impermissibly inflammatory.
  • A witness’s longstanding relationship and direct dealings with alleged conspirators supplied adequate personal knowledge for testimony about their drug-trafficking routines and communications.
  • Blanco’s role in preparing fentanyl for Boldt, her presence and participation during controlled purchases, and drugs and cash found in the shared bedroom supported the conspiracy verdicts.

Why It Matters

The decision illustrates the Eighth Circuit’s willingness to admit contextual evidence found near the site of charged drug trafficking, including evidence involving a different controlled substance, when it completes the story of the investigation and does not create undue prejudice.

It also confirms that a conspiracy conviction may rest on circumstantial evidence of knowing participation, even when a codefendant physically transfers the drugs. Presence coupled with knowledge, participation in conversations, assistance with distribution, and evidence recovered from shared living space can permit a jury to reject an innocent-bystander defense.
