I've been following this.
Yes, I do think her father knows. He did testify against her once already.
I don't know; of course she is crazy for doing this to that baby... But I don't think she's 'insane'. I think she knew what she was doing, and she just didn't want to bother being a mother. She liked to play, but not be responsible. Which is a huge problem with so many people now, but rarely to THIS extent.
She's lied the entire time. About where she worked, and other things. Taking the police to her 'place of employment' and then saying 'Oops... I got fired months ago.' She's never told the truth about anything! I'd love for the little girl to be alive... But that just doesn't seem realistic, so I actually can't wait for the evidence to get this woman and she can finally be outed for sure! She can't lie around forensics.
