So, got to kind of follow me here, okay. When I get the body, I don't alter it, you know, I don't wash it, I don't do anything to it if there is something of interest that I'm trying to see.
So in this particular situation when I look at some Michael Brown's hand there was kind of an area of discoloration in his thumb area on his right hand that I was concerned about that this could be some type of material discharged from a firearm.
To myself in looking at it, it is kind of like an experience thing, when I was looking at it, just the color of it, the nature of it, it didn't look like dirt to me. Specifically right near the wound, when I think about dirt, we have all been children or working on things that you have dirt, like dirt is all over your hands, it is not like in one little particular corner.
So essentially it was associated with that particular area and it just looked different to me. I did not think that this was dirt and that's why I decided to take the next step to look under the microscope to confirm what I was looking at through my eyes.
So that the next step was doing histology. So when I did this and I saw these little molecules here, the fact that they are very darkly pigmented, they are embedded in the tissue, it is hard for dirt to introduce itself into tissue. Dirt usually sits on top of things, it doesn't get into things.
So the fact that this is in the tissue, that let's me know that it had to be introduced into the tissue and that is going to be more consistent with products that are going to be discharged from a firearm that would be able to insert itself or get itself into those tissue. So that's why I feel this is not dirt, and this is particulate matter from the discharge from the firearm, if that makes sense.
