Have WMD stockpiles been located... by Zarqawi?

We've all heard about the latest round of beheadings served up by the savages and a number of us probably know that they are demanding the release of "muslim women" from prison as their ransome. But who are the women (all TWO of them) they want released? Dr. Germ and Mrs. Antrax.

Why have they gone to such great lengths to get these 2 women released? Could it be that they have their hands on chemical or biological ingredients and they need some help to mix them? I don't want to be an alarmist, but something smells very fishy, to me.
