That's a Tiny Mannequin!
"Police are looking for two women who stole a 'plastinated' 13-week old fetus from the Body Worlds 2 exhibit in Los Angeles. Surveillance tape showed the two thieves lingering at the exhibit, then taking the specimen from its case." LINK
One of our readers speculates: "They are women with hungry wombs who want to pretend they are pregnant like the women who have recently stolen other women's fetuses. Or they are abortion supporters who don't want people to see how well-formed a human being is at thirteen weeks."
Or maybe the women need it to model real little clothes. Or maybe they're filming a prequel to Weekend at Bernie's. Or, given that babies are as rare as gold, maybe the women hope to con someone into paying $100,000.00 for it.
