However, considering all of the physics even in
general, the limited head of a flashlight with protrusions concentrating the
force and sorely limiting energy distribution could not possibly account for
the dislodged skull fragment in conjunction with extensive fracture lines in
severity and distance. For that much energy to be distributed over that much
area of a dome without lacerating the scalp, the object of contact could not
have had anything even remotely resembling a cutting edge. A heavy, flat
cutting board is a possibility. So is a heavy iron skillet. However, in
weighing all the variables, the highest probability, is that the head was
not struck with a moving object, rather a moving head struck a stationery
object of a flat, or nearly flat surface.
