I guess the biggest question for me is figuring out where the murder took place. If somebody just lured her or forcibly took her off of the trail and committed the crime there, then that is confident, brash and risky. I would guess that that means this isn’t the first time the killer has done something like this.
And it seems like a random crime of opportunity, so even though she doesn’t fit the victim profile of the other stranglings in the Chicago area since 2001, I wouldn’t necessarily rule that angle out. The partially burned body is at least a potential link to some of those other cases too.
We know that even some of the most cruel serial killers have just seemed like normal guys or even family men to the people in their respective personal lives before they get caught. What if this seemingly normal guy was just out for a normal activity and saw an opportunity when she was alone and nobody was around and felt comfortable or confident in committing those horrible crimes because they had already done it multiple times without getting caught.
It also seems like a lot of serial killers escalate and end up taking more risks until they get caught. If this potential serial killer had become comfortable targeting the disadvantaged, then this would definitely be an escalation in my opinion. They could have acted out of character and committed an opportunistic crime outside of their MO, panicked when they saw the phone thinking she might have recorded something (not out of the question to think she was taking pictures or selfies while walking) and grabbed it, or maybe just stole it, and didn’t realize that it would ping towers until it was too late.
I would need to know for sure where she went missing and where her body was found and whether or not they have the cell phone. Also, aren’t cell phone pings kind of unreliable? At least sometimes? Like, even if it pinged from those apartments, it doesn’t necessarily mean that the phone was there? I don’t know.
Alright, that’s my rambling theory, but I understand people being skeptical of that potential link. Either way, I’m glad those cases were brought up, because I didn’t know about them and over 50 is quite a lot in around 20 years, even for an area with such a huge population.
