This is my first post, as I'm new here. I have read this entire thread and have been following this case closely.
Although it's entirely possible that JC has murdered before, I am not so quick to believe that. In my option he is an absolute train wreck in all aspects of his life. Being a SK requires some level of planning, execution and attention to detail. I don't see any of these qualities in JC. He is an unemployed (aside from day labor) drifter, alcoholic, ex-con loser.
I believe that (for the moment) IL was his first victim. I think he groomed her via online/texting, etc. I think it's possible that they did in fact meet up once (maybe twice) for coffee or something in the past. I say this because I believe she did in fact trust him to some degree. Personally, I would never go on a first time date to a three hour + baseball game - the whole event with parking/travel could go over six hours. This makes me believe she did like him enough to spend a significant amount of time with him.
I think they did in fact go to the game, as well as the bar downtown. I think JC was tipsy/slightly drunk, but nothing he wasn't already accustomed to. I think it's possible that IR brought him back to her place to continue the date, or maybe even to let him sober up, as a previous poster had mentioned. At this point, she began to pick up on his creepy vibes, and may have even started to panic (thus him saying she was "acting weird"). JC may have made sexual advances or was simply making her so uncomfortable that things began to escalate. I don't think JC wanted to leave her home - I think he actually thought it possible that he could develop a relationship with IR. His ego was shattered, and he became enraged. He choked her or suffocated her, causing her death. He then panicked, and thought of the best way to hide her body while he figured out what to do. In theory, the dismemberment and disposal of her body could have been very effective - IF he hadn't placed her remains in an empty recycling bin. Had he placed the remains in a GARBAGE (not recycling) bin that already contained trash (and hadn't already been emptied by waste management), he could have been some what successful.
This case is just horrifying. I just can't believe this poor woman's remains continued to sit in another garbage/recycling bin for an additional week.
