That said, the bottom line is that she and only she committed those horrendous murders and I find it interesting that so many freepers want to blame the 'village'.
I agree ---but when you look at the early childhood of other psychopathic murderers, you often see there was abuse and neglect. A mother's ability to love her children is often based on the kind of mothering she herself learned as a very small child. That doesn't let Andrea off the hook ---but I'll bet there were some serious issues in her family.
