Sandy Hook - The Scene of "Adam Lanza's Suicide"

According to an appendix to Sedensky's summary, Adam lanza committed suicide in Room 10 of SHES by reaching over his shoulder and behind his back while holding a full-size handgun in a forward firing position. The gun's muzzle was supposedly pointed sharply upward and positioned 13-14 inches below the apex of his skull, facing almost directly forward. Aside from the seeming impossibility of this feat (if anyone has any information about Lanza having been a quadruple-jointed contortionist with extraordinarily long limbs, please provide it), it is also notable that Lanza supposedly faced directly toward what is termed the "east wall" of Room 10 when discharging the fatal round. This means that the blood and tissue spatter resulting from his having blown his brains out with a high-power handgun at point blank range would have to be distributed over a broad area to the east of his body. It also indicates that Lanza's body would have been facing east as it came to rest on the floor, and the gun he used to inflict his head wound would necessarily have recoiled backward, to the "west" of his body.

Yet, look at the scene shown in the video linked below. At 0:37 of this video the scene of Adam Lanza's supposed suicide is shown (reportedly derived from photo 161 of 760 in the final report's Walkley photos). Notice how there is no appreciable blood or tissue spatter visible to the "east" of what is apparently depicted as Lanza's body. Also note how Lanza's body seems to be curled and facing the "WEST" wall of the room, while the purported instrument of death is lying to the "east" of his body.

All of this is completely opposite of what the appendices provided to Sedensky's summary by scene investigators require. What accounts for these blatant, demonstrable contradictions and inconsistencies? Were the crime scene investigators horrendously incompetent and unreliable, with the same relative proficiency and task acumen as trained baboons? Or, was the crime scene staged? Alternatively, was there no real crime scene, and the images supposedly captured in the Walkley file faked? If the crime scene was staged, were they merely sloppy in their efforts, or did they intentionally make the scene patently incredible and unbelievable in order to hasten the coming of O'Brien's denouement?
