(CNN) A Texas jury sentenced a former police officer to 15 years in prison Wednesday night for the shooting death of an unarmed African-American teen in a Dallas suburb.
The jury deliberated for 12 hours before deciding the fate of former Balch Springs officer Roy Oliver. In addition to the prison term, it imposed a fine of $10,000.
Oliver was convicted of murder Tuesday by the same jury for the killing of high school freshman Jordan Edwards, 15. He fired into a car full of teens on April 29 last year, saying he believed it was moving aggressively toward his partner.
Dallas County District Attorney Faith Johnson described Oliver as a “killer in blue” who violated his oath to protect citizens. Prosecutors sought a sentence of at least 60 years while the defense argued for 20 years or less.
