Theres no doubt in my mind that Casey is guilty.
The circumstantial evidence alone should have been enough.. Who goes out partying shortly after their four year-old disappears? If it were one of mine I would have either been bedridden or out searching for her.
Seems to me that he had hoped the baby wouldnt make it through the night, and when he realized that she did, he felt like the had to do something else. This is horrible. The killing of something so precious and innocent is something I just cant comprehend.
