I never heard of Dexter, Tom, but it is pretty cool. My training came on the physics side, with nuclear reactors and their neutron management and shielding design. But the principles and theory is identical; if you understand this shit, then you can design good radiation shielding.
This is the blood science behind it, briefly.

That has not been done with this case, and the medical examiner/forensics photographer apparently did not take the detailed photographs and measurements of exactitude. Just another brick in the wall, eh?
With this, if it was possible, we would have decent estimates of body position, body motion, and a better picture of what went down based on empirical evidence.
