The purpose of this new thread is to please discuss only the following theory. Any and all commentary, insights, suggestions for analysis or revisions, questions, or even just gut feelings are welcome - but only as long as they are please directly related to one of the 20 items below. Thank you in advance. 1. Maxie tried to lift the fully-extended scooter by the handle to take it downstair. 2. Foot section swiveled and bumped into the newel post (see photo with dent halfway up the post) 3. He's having trouble keeping the foot section from swiveling so he decides to put it over his right shoulder 4. The 7-pound foot section, at the end of the fully extended steerer tube, likely with his left hand on the handle and his right hand on the tube, then swivels and strikes him hard on the right shoulder and neck, explaining that completely and previously unexplainable plane of injuries. 5. Maxie reacts to the pain and uses both his hands to literraly swing the foot section away from him, exerting so much force on the steerer tube, alike swinging a baseball bat, that the foot section now swings violently in a counter-clockwise direction (when viewed from above). 6. The foot section strikes the flared/tapered edge of the newel post and banister. 7. All the damage on the hallway-facing edge of the newel post and banister match scooter components *exactly*, as you can no doubt also go confirm yourself. 8. The foot section bounces off the the banister as a result of that violent strike, moving the combined COG even higher - much higher as it is at the end of the fully extended steerer tube. 9. Not only is the combined COG much, much higher now after the foot section bounces off the banister, it is also hanging at the other end of the steerer tube - a very long lever. 10. The steerer tube, as Maxie continues to try to hold on to it as the scooter starts to succumb to gravity and starts moving downward, comes into contact with the corner/edge of the newel post facing towards the chandelier - that damage is clearly visible on the high-res photos, clearly the result of a metal object (in this case an aluminum pipe) hitting and then rubbing against it and leaving those dark rub marks you too can no doubt see. 11. The foot section of the scooter, still moving in a counter-clockwise direction (when viewed from above) after bouncing, exerted such a force on 40-pound Maxie at the other end of the steerer tube (lever) that he moved to what by then was his left and went down one step on the staircase. 12. The effect of the Combined-COG, by now incredibly higher than the Combined-COG graphed/reported by the experts, is now way above what would be required for Maxie to easily fall over that much lower part of the railing (one step down) 13. As if #12 wasn't already enough, the 7-pound foot section is exerting a huge force on Maxie, but I agree with you, only partially overcoming the effect of gravity. 14. As if #12 and #13 together were not already enough, the foot section is also still moving violently, and the momentum it generates at the other end of that lever/steerer tube, is more than enough to throw Maxie off balance 15. Maxie is literally catapulted over the banister. 16. The scooter violently strikes the chandelier, so hard in fact to snap one of the chain links, however, it takes a moment longer to actually rip that electrical cable, which slows down the descent of the scooter. 17. Maxie's 40-pound body literraly torpedoes straigh into the ground. Followed by the chandelier and the scooter. 18. Chandelier falls next to Maxie. They never come in contact with each other, thus no cuts. 19. Scooter lands on Maxie's back, creates those injuries in a "7 shape", strikes the back of his neck, and the relatively sharp edge of the foot section scrapes the skin off his back in two spots (the ones I earlier speculated looked more like carpet burns). Dina finds skin redisue in his shirt later. 20. This is the only scenario that explains both, the level of injuries Maxie suffered to his face, skull and neck, as well as those previously mysterious and extremely disconcerning shoulder injuries which occured in a completely different plane. RIP Maxie Shacknai.
