I'm probably about to piss some people off. But at this point in time, for many reason, I'm done caring about pissing someone off.
The other doll was a Barbie Doll left in a manner that could indicate the person that left it COULD have had some knowledge of how the girls were dumped.
This is a tough call. The person known to have left the dolls, has displayed some very odd behavior. My question is if the behavior is so odd, that some of us would have to feel he wouldn't be capable of carrying these killings out for an extended period of time.
Then again, perhaps he's ready to be caught, or has gone off his meds, or has a worsening mental illness. If that was the case, could he have stopped himself from killing since the bodies were found, and probably ended up slipping up and getting caught?
Is he compensating for knowing he can't kill because it's too hot and is doing this instead.
Whoever is doing these killings could just be so entirely different than anything we've seen in the past... it's hard to guess what his motives or capabilities are.
There are some pretty crafty people here on Webslueths. Much smarter than me. I can't make up my mind on this.
