Charleston, SC (WLTX) - Thursday marked the first full day of defense testimony in the murder trial for Michael Slager.

Slager is the former North Charleston Police officer charged in the shooting death of 50-year-old Walter Scott.

In April 2015 Slager pulled Scott over for a broken taillight. Scott fled the scene. After chasing Scott down a struggle occurred and moments later Slager fired at Scott.

Scott died as a result.

Eli Driggers was the first witness to take the stand. Driggers works for the North Charleston Police Department and handles the department's uniforms and gear. He showed the jury the type of gear Slager was using the day of the shooting.

Grant Federicks was the next to testify. Fredericks was admitted as an expert in forensic video analysis.

He said that Bill Williams testimony, which was given on Wednesday, was flawed.

He said the timeline Williams created and the way his presentation was showed may have had an effect on the jury's perception of how far away Slager was to Scott when he fired at him.

"Yesterday, Mr. Williams referred to it as a 4:3 aspect ratio. That's incorrect." Fredericks said. "Mr. Williams followed practices that are not acceptable by the forensic video community because using the player, my peers know that's the inappropriate way to use the video. It's not intended to be used that way."

During cross-examination the prosecution said the effects of perception do not change the fact that Scott was still 17 feet away from Slager when Slager fired his weapon.

They continued to argue that Scott was no longer a threat and Slager committed murder with malice and forethought.

Prior to testimony, Judge Newman chose the foreman of the jury. He selected the one black juror to represent and speak on the jury's behalf. Six white men and five white women make up the rest of the primary panel of jurors.

The jury heard from the defense's first witness on Wednesday. That testimony given by audio enhancement expert, David Hallimore.

The court adjourned at 2 p.m. on Thursday and will pick back up Monday at 10:30 a.m. Wednesday's testimony is expected to adjourn at noon because of Thanksgiving.
