Jeremy Cooper had faced up to three years in prison after being found guilty in a jury trial last year of criminally negligent homicide. He administered a dose of ketamine to McClain, 23, who had been forcibly restrained after police stopped him as the massage therapist was walking home in a Denver suburb in 2019.
The sentencing caps a series of trials that stretched over seven months and resulted in the convictions of a police officer and two paramedics. Criminal charges against paramedics and emergency medical technicians involved in police custody cases are rare.
