What Happened

Amber June Hyatt, 47, of Evergreen, Colorado, was sentenced to one year and one day in federal prison after pleading guilty to tampering with fentanyl vials at an oral surgery practice in Littleton where she worked as a surgical assistant.

Hyatt's roommate found fentanyl vials and vial safety caps in her purse and reported it, prompting the practice to alert the Jefferson County Sheriff's Office. An investigation found that boxes of fentanyl citrate stored in the practice's controlled-substance safe had been tampered with. Lab testing of a subset of vials found seven contained a replacement liquid in place of fentanyl, and one of those vials was also contaminated with bacteria.

Hyatt pleaded guilty to one count of tampering with a consumer product. On January 14, 2026, she was sentenced to one year and one day in federal prison, followed by two years of supervised release.

What Went Wrong

A surgical assistant was able to open sealed fentanyl vials, replace the contents, and return them to the practice's controlled-substance safe without detection until a private report from a roommate — not the practice's own controls — triggered law enforcement involvement. Key failures included:

  • Tampered vials were returned to usable stock in the controlled-substance safe without any check catching the altered contents before the report surfaced.
  • The diversion was uncovered through a personal disclosure to a third party rather than through the practice's own inventory reconciliation or physical inspection of vials.
  • At least one tampered vial was contaminated with bacteria, showing sterile-vial integrity was not being verified before use.
  • There was no indication of routine visual or physical inspection of vial seals and safety caps in the small-practice setting.

How It Could Have Been Prevented

  • Inspect vial seals, caps, and fill volumes at the point of use, not just at receipt, to catch tampering before a vial reaches a patient.
  • Reconcile controlled-substance stock in small practices on a frequent, documented schedule rather than relying on staff self-report.
  • Limit and log individual access to the controlled-substance safe, including after-hours or unsupervised access.
  • Train staff on the physical signs of vial tampering (replaced caps, altered seals, discoloration) as part of routine handling.
  • Establish a clear, known internal reporting channel so staff and outside parties who suspect diversion have an obvious way to escalate concerns.
