There is no question that, if this was a suicide, it was a rather strange one. Anyone familiar with True Crime knows that the way "murder staged to look like a hand gun suicide" is detected by comparing the position of the gun with the trajectory of the bullet. In this case, however, the First Responders moved the body and the hand gun before there were any photos so no one was exactly sure of the position of the body or the location of the gun. From what I can tell, it would be "unusual" for the gun and body to be positioned as the First Responed remembered it based on the know trajectory of the bullet; but not impossible. Thus the evidence could not "rule out" suicide even though there was definte cause for doubt.
