[My perspective]
If you look closely at the photo you will see blood smears on SSR's face(beard and mustache). How is that possible?
If he did die due to hanging there is no way for blood smears to appear on his face.
That too multiple places?
Looks like it was caused by a sharp object. A cloth/rope/fabric cannot cause such cuts. What tool was used for this? Where is it?
Try viewing the marks in a perpendicular angle and notice the line like variations.
How can a smooth linear fabric cause these variations in the ligature mark?
Maybe we're missing out on cruical points.
Maybe there's something no one has noticed yet.
Look closely and question everything you see.
There could be more clues.

Photos that require the entire face have not been attached for obvious reasons. You can find the photos on Google and cross check.
Photos attached in this thread have been enhanced to increase the exposure and color qualities.
Due to cropping, the photos maybe distorted.
