Responding to reports of a domestic disturbance, Wilson fatally shot a man who was stabbing his ex-girlfriend and wouldn’t stop. It was the first time in a dozen years on the job he had killed anyone.

The harrowing footage captured on the WOLFCOM body camera connected to his police radio showed 44-year-old Ronnie McNary shouting “Kill me! Kill me!” and refusing to stop the bloody assault before Wilson opened fire.

Thanks in large part to what the “body cam” caught on the night of Oct. 18, 2014, a Cuyahoga County grand jury found the shooting justified and Wilson is back on the job. He now has nothing but praise for the device that he believes may have saved his career.
