What Happened
A Massachusetts EMT paramedic tampered with fentanyl citrate vials stocked at the ambulance company where she worked part-time, replacing most of the drug with saline.
The paramedic worked part-time for an ambulance service company in Massachusetts from approximately March 2020 to early October 2020. On or about September 30, 2020, while working in Needham, she tampered with three fentanyl citrate vials by removing fentanyl citrate and replacing it with saline. Lab testing later found the liquid remaining in the three vials contained only approximately 4.4%, 6.8%, and 24.2% of the declared concentration of fentanyl citrate.
She was charged on June 24, 2022, and pleaded guilty on August 30, 2022, in federal court in Boston to one count of tampering with a consumer product. Sentencing was scheduled for December 7, 2022, with the charge carrying a maximum of 10 years in prison, three years of supervised release, and a $250,000 fine. The case was investigated by the FDA's Office of Criminal Investigations.
What Went Wrong
Diluted fentanyl vials remained in an ambulance's active narcotics stock without detection until lab testing was performed. Key failures included:
- Fentanyl vials carried on ambulances were not routinely inspected or potency-tested before or after each shift.
- A part-time EMT had access to controlled-substance stock without documented, reconciled chain-of-custody at each handoff.
- No process flagged the diluted vials until they were pulled for lab analysis, meaning any patient dosed from them in the interim would have received a substantially reduced dose without anyone knowing.
How It Could Have Been Prevented
- Require physical inspection of vial seals and visual fill-level checks for ambulance-stocked narcotics at every shift change.
- Maintain a reconciled chain-of-custody log for controlled substances handed off between EMS staff, including part-time and per-diem employees.
- Randomly sample and lab-test ambulance narcotics stock on a recurring schedule rather than only in response to a specific complaint.
- Train field staff to recognize and immediately report signs of vial tampering, such as inconsistent fluid volume or damaged seals.
