The trial of a white South Carolina police officer accused in the shooting death of an unarmed black motorist is entering its third week.

Michael Slager is the former North Charleston patrolman charged with murder in the April 2015 shooting death of 50-year-old Walter Scott. Cellphone video of the shooting showed Scott being shot in the back while fleeing a traffic stop.

The defense contends Scott was able to grab the officer's stun gun and was pointing it at the officer before the shooting.

The state continues its case Monday after already calling 27 witnesses.

Slager, who turns 35 Monday, could be sentenced to 30 years to life if convicted in Scott's death.
