They need to find whoever is doing this very fast too - the number of deaths in the short space of time is horrifying. In this day and age its ridiculous that women feel they have to pace the streets at night, in unsafe areas, just to be able to feed their children and themselves (which the majority of the time is why the do it).
Lets hope they find this sicko fast and I really hope the girls' families get justice (although, I doubt it, cushty "cell", TV, internet access, and they've probably got Nintendo Wii's in there for them to play aswell!)
