That could affect it. And what I should say to you, when we do autopsies in our line of work, we try to answer as many questions and issues that we can. We often, there are findings that we can't explain. So that even issues like the cause here, I can't really explain it. And that, that often happens in autopsies, you explain the major ones that answer the question, but not everything.
And there are other experts that is a gravel expert, they have gravel experts might have a better idea or somebody doing experiments on injuries to skin, which are very difficult to do now because it needs appropriate approval by boards that you can't do experiments on people that hurt people. However, they can do it on pigs and animals sometimes and there may be somebody around who is an expert on that, but it would be more able to answer the questions on that surface with the human skin. It is very similar to pig skin, would develop these injuries just from contact with the gravel falling with a certain force.
