Olmsted County medical examiner: fentanyl concentrations rising, autopsies and toxicology underpin local overdose data

Ross Reichert, Olmsted County medical examiner, briefed the board on forensic capacity and yearly mortality data, describing how thorough death investigation and toxicology work affect local overdose statistics and trends.

Reichert said the county’s medical‑examiner office and regional death investigators perform comprehensive autopsies and full toxicology on suspected drug deaths; those practices can yield higher documented counts because cases are actively investigated and tested. He told commissioners Olmsted County’s drug‑poisoning death rate is reported at about 20 per 100,000 people compared with a state median of about 23.6 per 100,000.

Reichert outlined caseload numbers for the year: roughly 1,895 deaths were reported to the medical‑examiner office, about 239 autopsies were performed and about 210 were complete autopsies. He said medical investigators and pathologists in the Southeast Minnesota region are experienced and that the office’s due diligence — including scene examination and toxicology — can reveal previously unrecognized drug‑related deaths. “We do a complete autopsy on every potential drug overdose of death, and our investigators are going to the scene and going very carefully through the scene, the prescription medications, everything that is there,” Reichert said.

On drug concentrations, Reichert said fentanyl levels in fatal cases have climbed compared with earlier years: where early fentanyl deaths sometimes showed single‑digit nanograms per milliliter, the office now regularly sees concentrations in the 20–30 ng/mL range in some fatalities. He said the higher concentrations contribute to lethality and also risk to first responders and others at scenes with highly concentrated fentanyl.

Reichert reviewed other mortality categories (natural causes such as heart disease and cancer remain the largest groups) and explained the medical‑examiner office’s role in classifying deaths for public health surveillance. He also noted an increase in alcohol‑related liver disease deaths compared with earlier years, reflecting broader public‑health concerns.

Board members asked about classification terms (poisoning vs. overdose); Reichert and staff explained public‑health reporting may use “poisoning/overdose” labels but that the fatality review team will examine autopsy and toxicology reports to clarify substances involved in fatal cases.

The presentation concluded with staff reiterating the value of robust forensic investigation to inform public‑health responses and program planning.
