Elijah McClain, 23, a black man had his cause of death determined differently in an updated autopsy report released on Friday.
An updated autopsy report made public on Friday claims that he was given a heavy sedative injection after being held violently.
Despite the discovery, the cause of 23-year-old massage therapist Elijah McClain's death was remained reported as unknown.
McClain was stopped by Aurora police for "being suspicious" and then placed in a neck hold and given ketamine injections.
In 2020, nationwide demonstrations against police brutality rekindled interest in McClain's killing.
The five suspects have not yet officially admitted guilt, and neither have their attorneys.
The city of Aurora consented to pay $15 million last year to resolve a lawsuit McClain's parents had filed.
