Wow...it's taken me a couple of hours to catch up after taking a break from this thread for the holiday! After reading lots of thoughts and opinions, I just want to re-iterate my personal beliefs about this case which I had shared many, many pages back
All IMO.
1) Being a local, I know he had plenty of ways to get out of town to more remote areas, based on the direction he was headed. He could've continued heading North, gone East or West, and gotten to either the interstate, or continued on to country roads which would've taken him to many secluded and rural areas. A lot of people are still speculating on how he got her into the apartment (and I know that's what we do on WS!), but I do
not believe he ever took her there. What other locals have said is 100% accurate. I consider CU to be a fairly populated, busy college town. But go a few miles in any direction and you hit country, farm land, trees, rivers, you name it.
2) I do not believe he has done this in the past. I agree with what another poster said about him being a very rare type of criminal. I think he lived out fantasy via the web, online gaming, and BDSM types of encounters from fellow members of FetLife. I think he had twisted, morbid thoughts that came to life via an extremely chance encounter. YZ was petite, of Asian decent, and appeared totally helpless in that moment. BC is obsessed with dominance and control. He went by her once, saw his opportunity, and came back to kidnap her, making his fantasy a reality.
3) He is a narcissist and a sociopath. He enjoyed this crime and felt he 100% got away with it,
even after authorities came to his apartment with a search warrant. He planned to go to the rally for YZ and enjoyed that as well. He kept 100% control over his companion during that time. I think that entire event had him very excited.
4) I think the FBI either has YZ's body already or has EXTREMELY reliable information that she is deceased. I agree with others that he may have taken photos or video, so they know she is deceased, but may not know where she is. They kept her family in the dark the entire time they were surveying him, maybe they've kept her family in the dark about this as well?
5) <modsnip> but something about Evan Bruno's comments have stood out to me. Wait until we hear the whole story, and there is way more to this than the public knows. I'm anxious to find out what this could be. <modsnip> A threesome fantasy gone wrong? Could another key player have just has much inside info and involvement as BC? I think more surprises are to come.
This is all IMHO and I'm not an expert on any of the above, just wanted to share
