SAN DIEGO – Former San Diego County Sheriff’s Deputy Aaron Richard Russell was sentenced in federal court today to 12 years in prison for fatally shooting a 36-year-old unarmed man who was struck four times from behind as he tried to run away from authorities. Russell was convicted by a federal jury in March following a two-week trial and less than seven hours of deliberation. The jury found that the defendant violated the civil rights of the victim, Nicholas Bils, by fatally shooting him in the back as he ran away.
