McClain was stopped while walking home from a convenience store on a summer night, listening to music and wearing a mask that covered most of his face. A 911 caller reported him as suspicious and the police stop quickly became physical with McClain, a 23-year-old massage therapist seemingly caught off guard, asking to be left alone. He had not been accused of committing any crime.

Prosecution witnesses testified that the sedative ketamine killed McClain. But prosecutors also offered medical testimony that the restraint of McClain by Aurora officers Randy Roedema and Jason Rosenblatt triggered a series of health problems that made it hard for McClain to breathe and more vulnerable to a fatal overdose.

Defense attorneys did not call any witnesses, instead using questions for prosecution witnesses to make their case that the officers did not cause McClain’s death.
