Both officers — who were tried together — had been charged with both crimes, as well as manslaughter. Mr. Roedema will be sentenced on Jan. 5.
First responders, including the police and paramedics, had placed Mr. McClain, 23, in a chokehold during a confrontation in Aurora, Colo., and injected him with a powerful sedative. He died in the hospital several days later. Three police officers and two paramedics were charged in his death, and are being tried in three separate trials. The joint trial of Mr. Roedema and Mr. Rosenblatt was the first.
The split verdict came as a shock among those who had been pushing for accountability since Mr. McClain’s death four years ago.
