PINELLAS COUNTY, Fla. — The prosecution rested its case Thursday afternoon after a day filled with expert witnesses, zoomed in and slow motion versions of that now infamous surveillance video and Michael Drejka's interrogation interview.

The video which shows Markeis McGlockton shoving Drejka to the ground before Drejka shot and killed him was played in full, slow motion, and zoomed in.

Prosecutors argued they wanted to give the jury a clear view of what went down in the parking lot from start to finish. However, the defense argues the video is altered and the quality isn't good.

The fatal shooting stemmed from an incident where Drejka confronted McGlockton's girlfriend, Britany Jacobs, for parking in a handicap spot outside the Circle A Food Store in Clearwater on July 19, 2018.

A self-defense and use-of-force expert was among those on the stand Thursday. While Roy Bedard couldn't comment specifically on the video and the actions of both men, he did give jurors a lesson in what he says justifies certain force.

Prosecution: “Based on your training and experience and expertise, what did you see when he took the firearm out? What kind of movement did you see?

Bedard: “I saw two movements previous to the shot breaking that were sort of waving or fanning to the left.

Each witness was challenged by the defense, including the state's toxicology expert when he commented on the MDMA found in McGlockton's system at the time of his death.

Dr. Bruce Goldberger: "Again, he looked completely normal."

Prosecution: "He wasn't freaking out, fighting with people, jumping over the counter stealing things?"

Goldberger: "No, and I wouldn't expect that in an individual consuming MDMA."

When questioned about the defense about the effects of the drug, Goldberg admitted the push shown in the video wasn't what one would expect for someone under the influence of MDMA.

Defense: "You watched the video and you saw when Mr.McGlockton came out and shoved Mr. Drejka."

Goldberger: "Yes it was almost like a school yard push."

Defense: "And it wasn't very lovey dovey or touchy feely as you just testified to this jury?"

Goldberger: "You're right, it was not."

THURSDAY MORNING COURTROOM UPDATES

"The person through the human eye might see it somewhat differently than what the video represents. Is that fair?" Defense Attorney John Trevena said.

Jurors watched a lot of videos Thursday, however, one part of the surveillance video they didn't see is McGlockton's 5-year-old son holding the door of the store open and then watch as his father was shot before rushing back into the store.

Prosecutors agreed not to show jurors that portion.

Another important piece of video they saw was Drejka's interrogation video just hours after the shooting.

"I shoot—I shoot to save my own a** and that's that," Drejka said in the video.

The interrogation video lasted about an hour and jurors heard Drejka explain his side of what happened.

Drejka: “If he's gonna hit me that hard to begin with from, from -- blindside from the get-go, what else should I expect?”

Detective: “Okay. All right. So you're on the ground. You, you said he was running at you but he only took, like, a step?”

Drejka: “He would have if he had cleared the, you know, cleared that and come around towards me again with that second foot, that would have been it."

Detective: “He only made one step?”

Drejka: “He barely made the second step before I pulled the trigger."

Detectives and deputies who responded the day of the shooting also testified Thursday morning.

Drejka faces up to 30 years in prison if he's convicted.
