The jury in the Michael Slager murder trial is taking a virtual tour of the crime scene.

An expert on laser scans of crime scenes, Eugene Liscio of Toronto, Canada, is testifying for the defense in the trial of Slager, the former South Carolina patrolman charged in the shooting death of a black motorist.

Liscio, using 3D laser scans of the scene in North Charleston, has been showing the jury the crime scene through a computer program. He's been taking screen shots from the program that the jury will be able to review during deliberations.

Slager faces 30 years to life if convicted in the death of the 50-year-old Scott who was shot five times in the back while fleeing a traffic stop in April, 2015. The shooting was captured on cellphone video that stunned the nation.

The defense in the trial of a former South Carolina police officer accused of murdering an unarmed black man is building its case that Michael Slager was a good officer who used force appropriately during his five years as a patrolman.

The defense continues its case Wednesday. Slager is charged in the April 2015 shooting death of Walter Scott as he ran from a traffic stop. Cellphone video of Scott being shot five times in the back by the white officer stunned the nation.

Late Tuesday, a defense expert testified that although Slager used a Taser 14 times as an officer, the use of force was appropriate.

Darren Porcher, a professor at Pace University and former policeman, said in some of the situations Slager faced, he might have used more force.
