Ok so I've been researching the Andrea Yates case a bit, still in progress.
This video is a bit hard to watch, but I am putting it here for reference. In it, it goes over how Andrea Yates calls her husband and tells him to come home, and he finds all of the kids dead. When she was asked why she did it, she said that she was a bad mom and was saving them from hell.
She was diagnosed with post-partum psychosis.
Here is the video:

What makes cases like these so complex and mysterious IMO is that the action appears to be inconsistent with other observed behaviors. In other words, I think we have all probably seen evidence that Debbie loved her children. Intentionally murdering Lisa is not consistent with that.
I don't know much about post-partum psychosis at all, but after seeing the Andrea video and hearing her motive, it struck me that she was possibly posessed, or in other terms, suffering from schizophrenia.
I then remembered the wine. It made me raise the question if the wine could have perhaps precipitated an episode of scizophrenia in Debbie and caused her state of mind to be so violently changed.
Here is what I found on that topic:

It would be interesting to me if there is any evidence in Debbie's past of schizophrenic behavior.
MOO! :twocents: :seeya:
