In a decision that has reignited a nationwide debate over medical accountability in police custody, the Colorado Court of Appeals on Thursday reversed criminally negligent homicide convictions against two former Aurora paramedics involved in the 2019 death of Elijah McClain.

The appellate ruling, issued on June 4 2026, sends the case back to the district court for possible retrials. It follows a December 2023 jury verdict that found paramedics Peter Cichuniec and Jeremy Cooper guilty of negligent homicide. Cichuniec was also convicted of second‑degree assault for administering ketamine, a conviction that the court left intact.

McClain’s death occurred on August 24 2019 when three Aurora Police officers confronted him after a civilian reported a suspicious person wearing a ski mask. Officers restrained McClain, applied a chokehold, and paramedics on the scene injected him with a 500‑mg dose of ketamine. He went into cardiac arrest on the scene and died six days later in the hospital. The incident sparked national protests and a broader debate over police use of force and the use of ketamine in emergency medical settings.

The criminal case against the paramedics was the first of its kind in Colorado. In 2023, a jury found them guilty of negligent homicide, a felony punishable by up to three years in prison and a $100,000 fine. Cichuniec received a mandatory minimum sentence of five years in prison, while Cooper was sentenced to four years of probation. Both sentences were later reduced to probation in September 2024.

The appellate court’s decision hinged on the standard of care that should apply to emergency medical personnel. According to the court’s opinion, the jury was instructed to apply a “common and ordinary” standard of care, which the court said misled jurors. The court clarified that the proper standard is that of a person in the paramedics’ profession under the circumstances of the case.

Attorney General Phil Weiser announced that the state will seek review from the Colorado Supreme Court. The Supreme Court’s decision could delay any retrial proceedings. Weiser’s office stated that it will continue to pursue the case, arguing that the reversal undermines accountability for the paramedics’ actions.

McClain’s mother, Sheneen McClain, posted a statement on social media expressing outrage over the ruling. She said, “I am not surprised by the denial of true justice for American citizens in the hands of government branches who allow criminal behaviors in their police agencies. They are corrupt and cowardly.” The statement was not confirmed by any official source.

The case remains a focal point for discussions about police restraint protocols and the medical use of ketamine. Several states, including Colorado, have since restricted or banned paramedics’ use of ketamine in the field. The incident also prompted investigations into the Aurora Police Department’s practices and led to the resignation and dismissal of several officers.

At present, the case is pending a new trial in the district court. The Colorado Supreme Court’s review, if granted, could either uphold the appellate court’s decision or reverse it. The outcome will have implications for how emergency medical personnel are held accountable in cases involving police custody and the use of sedatives.

The reversal does not alter the fact that McClain died after being restrained and injected with ketamine. It does, however, highlight the legal complexities surrounding the standard of care for paramedics and the challenges of prosecuting medical professionals in incidents that intersect with law enforcement actions.

The next steps for the case include the potential filing of a petition to the Colorado Supreme Court by the Attorney General’s office, the scheduling of a new trial if the Supreme Court does not overturn the appellate decision, and ongoing public scrutiny of police and medical protocols in Colorado.

The case underscores the broader national conversation about accountability for law enforcement and emergency responders, and it may influence future legislation and policy regarding the use of sedatives in police custody.
