I asked the judge for permission to allow the witness to use a mannequin for demonstration purposes and he granted it without objection from Golantz. I then stepped through the clerk’s corral to the hallway leading to the judge’s chambers. I had left Dr. Arslanian’s mannequin here until it had been ruled admissible. I wheeled it out to the center of the proving grounds in front of the jury — and the Court TV camera. I signaled to Dr. Arslanian to come down from the witness stand to make her demonstration.

The mannequin was a full-body model with fully manipulating limbs, hands and even fingers. It was made of white plastic and had several smudges of gray on its face and hands from experiments and demonstrations conducted over the years. It was dressed in blue jeans and a dark blue collared shirt beneath a windbreaker with a design on the back commemorating a University of Florida national football championship earlier in the year. The mannequin was suspended two inches off the ground on a metal brace and wheeled platform.

I realized I had forgotten something and went over to my rolling bag. I quickly pulled out the wooden dummy gun and collapsing pointer. I handed them both to Dr. Arslanian and then went back to the lectern.

“Okay, what do we have here, Doctor?”

“This is Manny, my demonstration mannequin. Manny, this is the jury.”

There was a bit of laughter and one juror, the lawyer, even nodded his hello to the dummy.

“Manny’s a Florida Gator fan?”

“Uh, he is today.”

Sometimes the messenger can obscure the message. With some witnesses you want that because their testimony isn’t all that helpful. But that was not the case with Dr. Arslanian. I knew I had been walking a tightrope with her: too cute and entertaining on one side; solid scientific evidence on the other. The proper balance would make her and her information leave the strongest impression on the jury. I knew it was now time to get back to serious testimony.

“Why do we need Manny here, Doctor?”

“Because an analysis of the SEMS tabs collected by the sheriff’s forensic expert can show us why the gunshot residue on Mr. Elliot did not come from his firing of a weapon.”

“I know the state’s expert explained these procedures to us last week but I would like you to refresh us. What is a SEMS tab?”

“The GSR test is conducted with round tabs or disks that have a peel-off sticky side. The tabs are patted on the area to be tested and they collect all the microscopic material on the surface. The tab then goes into a scanning electron microscope, or SEMS, as we call it. Through the microscope, we see or don’t see the three elements we have been talking about here. Barium, antimony and lead.”

“Okay, then, do you have a demonstration for us?”

“Yes, I do.”
