I will try my best. So start from the very beginning, upper left-hand corner you have Michael Brown and then upper right-hand corner you have our case number 2014-5143, exam case. And then it is headed as Supplemental Microscopic Examination Report.
Then the next line is, Microscopic Slide Examination.
And then the next paragraph, that's where I start to begin to describe some of the particular features that I'm seeing on the slides that were prepared of Mr. Mike Brown's gunshot wound to the hand.
So starting with skin and muscle I say, sections of the tissue from the right hand show multiple fragments of skin and single fragment of skeletal muscle.
What I was telling you before there is all of those little bits of tissue there, there is different fragments there and then one of those pieces was a piece of muscle, but it is not represented on what you just saw there. That was just one of the pictures and there is lots of things to look at, but that's in totality what I'm looking at.
So all of those fragments in that tissue block I looked at each individual one of them, every little corner under the microscope, so that is what that first sentence means.
Next, I say there is a darkly pigmented foreign particulate matter present on the superficial surface.
So that dark material that you guys saw, that is more in a deeper layer of the tissue, but on the top. Like if you think of the top of a cake, some of that similar type of material is sitting on the superficial, that means the top portion of some of those skin fragments.
And the stratum corneum, on your hand skin has different layers. On your palmer skin, you have a very thick layer called stratum corneum, it is kind of the more superficial layer of your skin. It is kind of like where your skin eventually sheds and it's kind of similar to what dandruff is. That is what the stratum corneum is.
So that particular layer there is pigmented material embedded within that superficial layer.
As I was telling you before, something has to introduce or cause those little particles to get pushed into that particular area, and that's what I'm talking about right here.
Also embedded within the stratum corneum of the skin fragments. A mixture of pigmented and non-pigmented foreign particulate matter is present focally within the dermis.
So when I was showing you that previous picture, there was pigmented material, that was the darker material and there was some, some things a little white in there, kind of shiny, that's the non-pigmented material. So there is a spectrum of items within the skin and that pink area that I was showing you, that's the dermis.
So when you have skin, you have the stratum corneum, you have a granular layer, beneath that you start to get into your connective tissue layer of your skin, which is the next layer beneath and that's where you will kind of see pinkish tissue, that's the dermis.
So in the dermis, deeper into the tissue below the skin, you still have those little foreign particulate matter introduced into the tissue.
So some of the skin tissue fragments within the skeletal muscle tissue fragment. So as I was telling you before, in all of those little pieces that I had there were different types of tissue, I had a piece of skeletal muscle. Skeletal muscle is even deeper than the skin, deeper than the dermis and the next layer will be muscle.
So deep in that tissue injury I took some muscle out too. The muscle that I looked at under the scope also had some of that foreign particulate matter. So this matter, this foreign material was getting embedded deep into the tissues.
Some of the non-pigmented particulate matter is polarizable. All that means is that when you polarize something, polarize means basically reflecting light. So there is some of the material that's in there is able to reflect light and some of the material doesn't. It is kind of a nonspecific thing, but it is important for me to describe everything that I'm seeing to let, you know, let people know that there is a mixture of things in here.
But some reflect light, some don't. The previously described particles of foreign particulate matter are consistent with the products that are discharged from a barrel of a firearm.
That last statement is simply meaning that the things that I'm seeing under the scope in my opinion are being introduced into the hand as foreign material coming from another source. And that other source, in my opinion, what I'm seeing is consistent with coming from the barrel of a firearm, not being dirt introduced from another place, but specifically coming from something else due to the nature of the particles, how they're distributed in the skin, where they are distributed in the skin, and how they got into those particular levels.
