I STRONGLY beleive that she used chlorophorm to make her daughter pass out so she could run inside to have a few sexy hours with her boyfriend who doesnt like kids. She came back out, saw her daughter had died, and didnt know what to do so she got rid of the body. But uh oh, she left human remains in the car and traces of chlorophorm. Not to mention you should NEVER use your own computer to look up something you dont want others to find out about because every single keystroke youve ever made is permanently on that computer so dumb idea.
But lets just get to the point that shes a terrible mother who deserves to rot in hell. Even if she didnt mean to kill that baby... SHE DID because she wanted to have fun with a boyfriend and didnt have anywhere to drop her kid off at. I wont even go into a gas station to pay for gas without taking my daughter inside with me... how can you be so ignorant?
