The remarks from his friend that he is shocked because the alleged Perp didn't seem like "that kind of guy"; remarks that he didn't seem as if anything was wrong....
Well no kidding. Miscreants *don't care* about the people they kill. They don't care at all! They do not have the ability to be empathetic. Chelsea was just a thing to kill and discard. He apparently kept trophies to relive the killing, and derive enjoyment from.
There is no sentiment that I can express to adequately say what I want as punishment for this useless and evil human being. I know that the courts and the prisoners will exact the proper judgement.
I really, really hope that LE will continue to dig deep on this one. Perps who kill like this, keep trophies, etc. are not novices. I venture to guess this is *not* his first murder. I will not be surprised in the least if he is associated with other cases; IMO there is a very high likelihood he is.
And, as I stated earlier, I would look for other nefarious associates. I will be very surprised if he acted alone. Very.
