It’s possible, but probably falling on the edge of a bathtub would have done that too. I’ve been to the Ritz Carlton and I doubt that somebody could have taken him up to the roof and pushed him off, dragged his body back, put it in his bed, and gotten away without anybody noticing. They have a very attentive staff.
Is there any reason anybody would want to kill this man in the first place?
Note to self: Never fail to tip room service and staff the proper amount.
There would be video of Saget (and anyone else) entering the roon in any case and it was no doubt thoroughly reviewed.
