A disorganized offender acts spontaneously, has a low IQ, poor work habits and lives close to where the crime was committed. I would like to know if Corrie and Scott were friends with any of Scott's acquaintances from his time in prison.
I would like to know the time line of the crime and also the autopsy results. If we had that information, we could understand a lot more about this crime.
Now that's an idea. It would be possible that someone from when Scott was in prison "stopped by" and Scott wasn't there and Corrie was in a vulnerable state. (On the other hand, we haven't heard that she was raped. I think it would be unusual for a stranger to kill someone without having first sexually assaulted them or robbed them.)
I just hope LE is making good progress.
