I've always been fascinated by mysteries, particularly unsolved crime cases. Your comment about Casey's possible revelation was quite interesting. I've always wondered why, when someone KNOWINGLY commits murder, they try so hard to cover it up? On the surface that may seem like a simple question, but I've actually spent time thinking about it, pondering the various possibilities. I think there are two main reasons:
2) SHAME. People are ashamed of what they've done and will do or say anything to have people believe them.
1) FEAR OF GOING TO PRISON FOR LIFE. This is #1 and people will do anything, say anything, throw anyone under the bus in order to beat the charges. I believe many perps lie in bed at night, making deals with God, e.g. "If You get me out of this, I'll follow You and never do anything wrong again!"
The most interesting thing (to me) about a murderer who walks free is the gnawing guilt (and fear) that grows in their gut as they approach the end of their life. When the flames of Hell are licking at their deathbed, I wonder if they feel it was worth it.
NOTE---I must state I firmly believe murderers can be forgiven and thus, accepted into Heaven. But I also believe God wants them to PUBLICLY admit what they've done. That may be a deal breaker for many, who take their secret to the grave.
I remember the look on OJ’s face when the guilty verdict was read at the trial in NV. Stunned disbelief as he realized he didn’t get away with it this time.
I think Casey has always escaped responsibility for her bad behavior due to her parents covering for her. This time its too big and her parents have not been able to save her.
If found guilty it will be interesting to watch her and see her interact with her parents. I think she will blame them.
