During the stop, he resisted officer contact and a struggle ensued, the report says. On one of the officers' body cameras, McClain is heard saying, "I'm an introvert, please respect the boundaries that I am speaking."
Bodycam video shows him telling officers that he was trying to stop his music to listen to them, then they begin to arrest him. One officer is heard telling another, "He just grabbed your gun, dude."
When paramedics arrived at the scene, they administered the drug ketamine to sedate McClain, the report said. According to a letter from the district attorney, McClain suffered a heart attack while in the ambulance and was declared brain dead three days later.
An autopsy did not determine a cause of death but listed intense physical exertion and a narrow left coronary artery as contributing factors, according to the police overview. The coroner found the amount of ketamine in his system to be a therapeutic amount.
In February this year, a police review board declared, "[t]he force applied during the altercation to include the carotid control hold and the force applied during the altercation was within policy and consistent with training."
