Sentencing resumed Wednesday for a former Texas police officer convicted of murder.

A jury  found Roy Oliver guilty  Tuesday in the shooting death of an unarmed black teenager.  Oliver shot and killed 15-year-old Jordan Edwards back in late April 2017 when Oliver fired at a car the teen was riding in.

Oliver's lawyers claimed he fired into the vehicle to protect his partner.  He was fired  from the Balch Springs Police Department days after the shooting.  Oliver was found not guilty of two lesser charges — manslaughter and aggravated assault.  The murder conviction is a big deal, though.  Data compiled  by a Bowling Green State University associate professor show that between 2005 and mid-April 2017, 59 non-federal police officers were arrested and tried for on-duty fatal shootings.

Of the 28 officers who'd been convicted — only five were for murder.

And four had already been overturned on appeal.  Oliver faces five to 99 years in prison.  Additional reporting from  Newsy affiliate CNN .
