Ok well this is just weirderer now. Those DM's are from Jan 16 2013. The Alabama @LennayKay was created the same day according to this article.

So this means the DM's were sent that day, then they deleted the account and then someone (trolling) created it within a few minutes/hours of the story breaking.
So it was legit owned by the hoaxer, then he deleted it after confessing, then someone quickly jumped in to make it again.
