Injection Marks on Jackson's Neck

Michael Jackson had injection sites on his neck, according to law enforcement sources.

As we first reported, Jackson had "dozens" of injection sites and punctures all over his body the day he died. Law enforcement sources tell us some of these injection sites and punctures were old and some were fresh. They were found, we're told, on his upper arms, upper legs, ankles, inside around his knees and the neck.

Dr. Arnold Klein told Larry King, "

." Klein, who saw Jackson multiple times in the weeks before his death, did not explain why he didn't notice marks on the singer's neck and other places.
