.Whether they would later vote their conscience was another matter.FiftyIt was now time to bring in the big prop to drive Dr.Arslanian’s testimony home.“Doctor, did you draw any other conclusions from your analysis of the GSR evidence that supported the theory of transference you have outlined here?”“Yes, I did.”“And what was that?”“Can I use my mannequin to demonstrate?”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.”“Please explain it to the jury.”Dr.Arslanian extended her pointer and faced the jury.Her demonstration had been carefully planned and rehearsed, right down to my always referring to her as ‘doctor’ and her always referring to the state’s forensic man as ‘mister.’“Mr.Guilfoyle, the Sheriff’s Department forensic expert, took eight different samples from Mr.Elliot’s body and clothes.Each tab was coded so that the location it sampled would be known and charted.”She used the pointer on the mannequin as she discussed the locations of the samples.The mannequin stood with its arms down at its sides.“Tab A was the top of the right hand.Tab B was the top of the left hand.Tab C was the right sleeve of Mr.Elliot’s windbreaker and D was the left sleeve.Then we have tabs E and F being the right- and left-front panels of the jacket, and G and H being the chest and torso portions of the shirt Mr.Elliot wore beneath the open jacket.”“Are these the clothes he was wearing that day?”“No, they are not.These are exact duplicates of what he was wearing, right down to the size and manufacturer.”“Okay, what did you learn from your analysis of the eight tabs?”“I’ve prepared a chart for the jurors so they can follow along.”I presented the chart as a defense exhibit.Golantz had been given a copy of it that morning.He now stood and objected, saying his late receipt of the chart violated the rules of discovery.I told the judge the chart had only been composed the night before after my meetings with Dr.Arslanian on Saturday and Sunday.The judge agreed with the prosecutor, saying that the direction of my examination of the witness was obvious and well prepared and that I therefore should have drawn the chart sooner.The objection was sustained, and Dr.Arslanian now had to wing it on her own.It had been a gamble but I didn’t regret the move.I would rather have my witness talking to the jurors without a net than have had Golantz in possession of my strategy in advance of its implementation.“Okay, Doctor, you can still refer to your notes and the chart.The jurors just need to follow along.What did you learn from your analysis of the eight SEMS tabs?”“I learned that the levels of gunshot residue on the different tabs greatly differed.”“How so?”“Well, tabs A and B, which came from Mr.Elliot’s hands, were where the highest levels of GSR were found.From there we get a steep drop-off in the GSR levels: tabs C, D, E and F with much lower levels, and no GSR reading at all on tabs G and H.”Again she used the pointer to illustrate.“What did that tell you, Doctor?”“That the GSR on Mr.Elliot’s hands and clothes did not come from firing a weapon.”“Can you illustrate why?”“First, comparable readings coming from both hands indicate that the weapon was fired in a two-handed grip.”She went to the mannequin and raised its arms, forming a V by pulling the hands together out front.She bent the hands and fingers around the wooden gun.“But a two-handed grip would also have to result in higher levels of GSR on the sleeves of the jacket in particular and the rest of the clothes as well.”“But the tabs processed by the sheriff’s department don’t show that, am I right?”“You’re right.They show the opposite.While a drop-off from the readings on the hands is expected, it is not expected to be of this rate.”“So in your expert opinion, what does it mean?”“A compound-transfer exposure [ Pobierz całość w formacie PDF ]
