Two Denver-area paramedics were convicted Friday for giving a fatal overdose of the sedative ketamine to Elijah McClain in 2019 — a jury verdict that experts said could have a chilling effect on first responders around the country.

The case involving the 23-year-old Black man’s death was the first among several recent criminal prosecutions against medical first responders to reach trial, potentially setting the bar for prosecutors for future cases.

It also was the last of three trials against police and paramedics charged in the death of McClain, whom officers stopped following a suspicious person complaint. He was injected with the sedative after being forcibly restrained. The case received little attention until protests over the 2020 killing of George Floyd in Minneapolis.

An Aurora police officer was convicted of homicide and third degree assault earlier this year, while two other officers were acquitted. The jury on Friday found Aurora Fire Rescue paramedics Jeremy Cooper and Peter Cichuniec guilty of criminally negligent homicide following a weekslong trial in state district court. They could face years in prison at sentencing.

The jury also found Cichuniec guilty on one of two second-degree assault charges, which brings the possibility of an enhanced prison sentence and required that he be taken into immediate custody. Cooper was found not guilty on the assault charges and was not taken into custody.
