LOS ANGELES - An eccentric California salvage diver was Sunday preparing a mission to the north Arabian Sea to recover Osama bin Ladens body as proof the Al-Qaeda leader really is dead. Bill Warren, 59, has vowed to scour the seabed to find the corpse and deliver photographic evidence that the terror leader was killed, the New York Post reported. Warren, who has discovered more than 200 undersea wrecks, told the Post he was taking on the mission to expose the truth. Im doing it because I am a patriotic American who wants to know the truth. I do it for the world, he said. Warren said he expected to spend about $400,000 on a two-week jaunt next month. He planned to rent a ship in India for $10,000 a day, and spend another $1,000 a day for a remote-operated submarine.
