You know, I just joined this site, and while I don't believe that anyone survived for sure (I'd like to believe so), somehow I don't think there would have been a "happily ever after"...I know that if I were in their place, the "survivor" that is, I wouldn't be happy ever again knowing that my whole family got shot, stabbed, and beaten to death.
A survivor, maybe.
A happily-ever-after story? Never.
