I think this poor woman was suffering from Postpartum Depression with Psychosis, it is sad that someone in her life (perhaps her husband) did not identify this before she went this far. I can guarantee that there were symtoms that she was out of her mind before it went this far.
She really needs some help!
I also feel sorry for all the people she has hurt, her daughters father, and all the family including her current husband and 8 month old baby girl. All the people that volunteered their time and money and energy for the crimes she has committed.
I pray that she can get help and I am sure she will pay in someway for her crimes.
