@Lana_Patrick:
I don't think they are dead. They might not make it to the cover stories, but back on that time, Oda didn't kill many characters. Hey Pell, wassup?
Weeelll, he killed Mr.11…. I guess.

@Urouge:
Bounty hunters don't go to prison. And after Whiskey Peak ended, they were enemies of BW. Staying there seems like a bad decision on the chance that BW came back.
They didn't have anywhere in particular to go (and they might have, we really don't know), but any random place seems like a better choice to me. Not to mention the fact that… well... Whiskey Peak sucks. It didn't even have much food.
BW's bounty hunters go to prison, if not i don't understand why Smoker arrested mr.11, but since, as you said, mr.9 and ms.monday aren't anymore part of BW, you're right.
I doubt they could scape from there without any ship or log pose, but that's irrelevant, the important is.. why so hate towards whisky peak, it has a cementery shaped like a cactus, and a poorly built and seemingly destroyed town, and a river through the island (or not, i even can't remenber this) and.. and.. nothig more, but… but... if mr.9 and ms.monday stayed there, sure now it's all rebuilt and is a good town for receive the pirates which have chosen that path , which doesn't seem a good idea at all, well...
