Thank you! And as your quote shows, it leaves little to no marks. It was used back in the day to acquire cadavers to sell to med schools as there were no indications that the cadaver had in fact been murdered.
Another thing that makes me question the blood evidence...I have been hit with a small pebble, after it was flung out of a lawn mower, and it hit me hard enough to draw blood, but, it left a bruise and welp that were very noticeable. I feel if he had been struck with these items(rocks, telescope/stand) with any amount of force, there would be clear evidence pointing to what exactly he was hit with and the marks would be fresh, and easily recognizable.
