A white former Texas policeman was jailed on Wednesday (Aug 29) for 15 years over the deadly shooting of an unarmed black teenager in a Dallas suburb last year that fuelled a national debate over possible racial bias in US policing.
The same jury that convicted Roy Oliver, 38, of murder on Tuesday in the death of Jordan Edwards, 15, deliberated for several hours before deciding his prison sentence.
Oliver's conviction was a rare instance in which an officer was found guilty of murdering an unarmed person.
In emotional testimony during the penalty phase of the trial on Wednesday, Oliver's mother asked the jury to sentence her son to the minimum five years, in large part because of the needs of his young son, who has autism.
"That's my prayer, because he could still have such an impact on that child's life," Mrs Linda Oliver told the jury.
Two police officers who worked with Oliver and a neighbour were among those testifying as character witnesses.
Prosecution witnesses on Tuesday included Edwards' father, Mr Odell Edwards, who said the last thing he told his son was that he loved him.
"It's just not the same without Jordan around," media quoted Mr Odell Edwards as saying.
Oliver, along with another officer, had responded to reports of underage drinking at a house party in the predominantly black and Hispanic city of Balch Springs, about 25km south-east of Dallas.
Oliver fired his rifle several times into a car with several teens inside, prosecutors said. Edwards, a standout high school student and athlete, was shot in the head and killed.
The jurors deliberated for about 12 hours over two days before reaching their verdict, after a trial begun in mid-August.
Oliver was a trigger-happy policeman who sent the teenager to an early grave, said Mr Michael Snipes, the first assistant district attorney.
The arrest warrant for Oliver said he and the other officer tried to stop a car at an intersection near the party. The other officer broke a passenger window with the butt of his gun.
Police body camera images displayed to jurors showed the car was moving away from Oliver when he fired at it.
Oliver's defence attorney, Mr Jim Lane, said the vehicle was a threat to Oliver's partner that night and he reacted to save his partner by firing into the car.
