I call BS on this being an honest representation of a 95 pound, 9'1" rattler.
Firstly, notice that he is holding the snake several feet in front of him, in a photo taken with an extreme wide angle lens... making the snake look disproportionately large in comparison to the person.
Secondly, even if that snake was a large as this picture makes it seem, it still doesn't look to me like a 95 pounder... maybe a 50 pound snake, but I doubt even that.
Thirdly, if that snake was 95 pounds, and he was holding it up on the end of a 3 foot long pole, it would be quite cantilevered, and would seem like several times that weight. Judging by the looks of him... not particularly well built, and not struggling to hold it up... I doubt that snake was anywhere close to 95 pounds.
Lastly, we don't know the size of that man, but he might be a little feller, under five feet, chosen to make the snake look dramatically large by comparison, for all we know.
Anyway, I would let the snake live, if possible. I've encountered many hundreds of rattlers, and never had to kill one, yet. If it was dead, and I was going to skin it, I'd probably have to choose my Pepper Shaker for that task.
