The original autopsy report listed the cause of McClain’s death as “undetermined.”
“Simply put, this dosage of ketamine was too much for this individual and it resulted in an overdose, even though the blood ketamine level was consistent with a ‘therapeutic’ concentration,” CIna wrote. “I believe that Mr. McClain would most likely be alive but for the administration of ketamine.”
Cina, who was assisted at the autopsy by Broncucia-Jordan, wrote that based on his training and experience, he still believes the manner of death is “Undetermined.”
“I acknowledge that other reasonable forensic pathologists who have trained in other places may have their philosophy regarding deaths in custody and that they may consider the manner of death in this type of case to be either HOMICIDE or ACCIDENT,” the pathologist added.
CIna could not determine whether the carotid hold contributed to McClain’s death, he added.
But “I have seen no evidence that injuries inflicted by the police contributed to death,” he wrote.
The amended autopsy report was signed in July 2021. It was released Friday after a Denver District Court judge approved the coroner’s emergency motion.
McClain’s death days after his interactions with police brought renewed scrutiny of the use of carotid holds and ketamine during law enforcement stops. His case gained renewed attention during Black Lives Matter protests in the wake of the police killings of George Floyd and Breonna Taylor.
Last year a grand jury indicted three police officers and two paramedics involved in the McClain case. They face charges of manslaughter, criminally negligent homicide and other charges.
