I don't know what a "traditional" burial is for a Muslim. And while I have no sympathy for this nut case scumbag, it was smart not to desecrate his body. There is no sense in stirring up the "average" Muslim and creating more converts to his extremely small bunch of fellow extremist/nutcases. Much better to get rid of him with a modicum of respect, with no tomb or site to pilgramage to. Good riddance and hopefully, a very small notation in history books.
