There are three layers which surround the brain. The outermost layer is referred to as the dura mater. After a severe head injury such as what JBR received, blood collects rapidly in under this layer from the broken blood vessels, resulting in a subdural hematoma. They are usually huge, especially in a head injury of this magnitude. JBR's hematoma was very small, only about 2 teaspoons of blood, which means that it consisted of only the residual blood which was in the surrounding capillaries at the time, which means that her heart was no longer beating at the time she was hit on the head. I have not read Dr. Lee's book yet and will need to pick that up. Given the fact that his stated opinion is that she was struck on the head first, how does he explain the fact that the SDH was so very small?
