Why would a drug dealer kill her? That possibility does not make much sense in my opinion. I am also convinced that her boyfriend (JW) had nothing to do with it, as he was not with her that night and he was the one who searched for her next day and notified her parents.
I think the key to the story is that "activity" in the alley where the keys were found. The fact that the police does not release the name of the person who was with her at that moment makes me think that they consider that person a real suspect, not just a POI. If that person was just a POI, why would n't the police disclose his/her name? The police may be building a case, but they may not have sufficient evidence to bring charges and make an arrest. Not having a body makes things difficult.
The reason I sad DD (drug dealer) was b/c I was referring to one of the POIs who has been rumored to be one. I was meaning him specifically. There was commentary earlier that perhaps she went to this DD's house after JR's and I'm saying that while there, MAYBE she was murdered.
I kinda feel like we've been at least minimally introduced to CR, JR, and JW, even lest to MB and DR, but yet not really at all to AB and ZO. Then even still, there are at least 3 other POIs unnamed. It's hard for me to peg CR, JR, JW and maybe even MB and DR as murderers. I find it also hard to believe a random abduction. That leaves AB and ZO, along with some about whom we have no clue. I could "but" a DD murder in the sense that she was opening her mouth to much at Sports and they got rid of her, or took advantage of her when she showed up at their place perhaps.....
