The Latest the trial of a former South Carolina police officer charged with murder in the shooting of an unarmed black motorist (all times local):

9:30 a.m.

Michael Slager is on the witness stand in his murder trial in South Carolina.

Slager is the white former North Charleston patrolman who repeatedly shot Walter Scott in the back last year as the unarmed black motorist tried to run from a traffic stop.

The shooting in April 2015 was captured by a bystander on cellphone video that stunned the nation. Jurors have watched the video repeatedly during the trial.

Slager took the stand after Judge Clifton Newman reminded him he has a constitutional right not to testify. Slager said he understands that right and wanted to speak anyway.

Slager faces 30 years to life in prison if convicted of murder. The jury is expected to begin deliberating later this week.

Former South Carolina patrolman Michael Slager is taking the stand to tell his version of what happened when a black motorist was gunned down while fleeing a traffic stop.

Slager, who faces 30 years to life if convicted of murder in the April 2015 shooting death of 50-year-old Walter Scott, is expected to testify in his own defense Tuesday in a Charleston courtroom.

Scott, who was black, was shot five times in the back while running from the white officer. The shooting was captured by a bystander on cellphone video. Slager was fired from the North Charleston Police Department and charged with murder when the video became public.

The defense contends Scott wrestled with the officer and got control of Slager's Taser before the shooting.
