User blog comment:Monkey.D.Me/OPSI case 8 Who killed Queen Otohime/@comment-3986064-20110530142604

It could've been Hodi for his hate and rage and also his dislike of her ideals of peace between humans and fishmen, to make Arlong proud. But I go for Decken, being pretty desperate and in need for what his ancestor urged for, he decided it doesn't matter who he kills, even just to make himself an opportunity and make his plan a success. He is first on my suspect list
