Colorado Appeals Court Overturns Homicide Convictions for Paramedics in Elijah McClain Ketamine Case

A Colorado appeals court has thrown out homicide convictions for two paramedics who injected ketamine into Elijah McClain, the 23-year-old Black massage therapist who died in 2019 after being pinned down by Aurora police. Associated Press reported the court ordered new trials for Jeremy Cooper and Peter Cichuniec on June 4, 2026, citing serious errors in how the jury was instructed on the legal standard of care.
The ruling is the latest twist in a years-long case that sparked national protests, cost Aurora $15 million in a civil settlement, and pushed Colorado to pass new laws restricting ketamine use by paramedics. Cichuniec's second-degree assault conviction — for unlawfully administering a drug — was upheld, but the homicide charges against both men were vacated.
On August 24, 2019, Aurora police stopped McClain after a 911 caller reported a suspicious person wearing a ski mask. Officers put him in a carotid hold, briefly cutting off blood to his brain. When paramedics Cooper and Cichuniec arrived, they diagnosed McClain with "excited delirium" — a contested condition used to justify chemical sedation — and injected him with 500mg of ketamine.
The dose was meant for a patient weighing over 200 pounds. McClain weighed roughly 140 pounds, according to Associated Press. He went into cardiac arrest in the ambulance and was declared brain dead six days later. His death became a rallying point for the Black Lives Matter movement and led Colorado Governor Jared Polis to appoint a special prosecutor to take over the case.
The appeals court found that the trial judge failed to give jurors clear enough guidance on how to apply the medical "standard of care" to the homicide charge. Legal analyst Scott Robinson noted the jurors had expressed confusion during deliberations, and the judge did not fix the problem. That gap, the court ruled, was enough to warrant entirely new trials for both paramedics.
The defense also argued an inconsistency in the original verdict: Cichuniec was convicted of assault for administering the drug, while Cooper — who actually gave the injection — was acquitted of the same charge. Critics of the ruling, including civil rights advocates, say the reversal sends the wrong message. "It's disturbing and mind-boggling," activist Candice Bailey said, arguing it undermines accountability for Black lives.
Even before the appeals court acted, the original sentences had been scaled back. Cichuniec was first sentenced to five years in prison in March 2024. But by September 2024, Judge Mark Warner had cut that to four years of probation, citing "unusual and extenuating circumstances." Cooper received just 14 months of work release and four years of probation — never serving prison time at all.
Elijah's mother, Sheneen McClain, has called the incident "murder" and "kidnapping" from the start. She has been sharply critical of every leniency shown to the men involved. Colorado Attorney General Phil Weiser said after the reversal, "Bringing these cases to trial was the right thing to do for justice," and pledged to pursue new trials.
The McClain case forced a hard look at how ketamine is used in the field. In 2021, Colorado passed HB21-1251, which sharply limits ketamine use in pre-hospital settings and bars police from pressuring paramedics into medical decisions. The law was a direct response to what happened to McClain — a man who was never suspected of a crime and begged officers to let him go.
The case divided the EMS community. Many paramedics feared the convictions meant honest clinical mistakes could land them in prison. National EMS associations reported a 13% drop in paramedic applications since 2019, partly tied to rising legal risks. Now, with new trials ordered, both Cooper and Cichuniec face an uncertain professional future — felony convictions would permanently strip their medical licenses.
