(Respectfully snipped) After re-reading your list of facts above, I have to say that none of those things disprove premed. I don't see why you think they do. All of those actions and events described above (w/ the exception of #5, in which I think you meant to type June 15) occured AFTER the murder. All actions taken by a murderer after a killing are to ensure they don't get caught. What you have laid out above in 1-9 are just behaviors and actions KC took to prevent getting caught; they don't disprove premed. As for #5, the big blowout between her and CA........that doesn't disprove premed either. On the contrary, I think it made her so enraged, she then acted on that rage, a rage and resentment that had been brewing.
IMO, we can beat this nag and send her to the glue factory, but the duct tape is going to nail her.
