I don’t really know other than if he had another set of clothing underneath, he might’ve done so to look like a different person.
There’s not much discussion about how the vehicle LE believes he drove fits into the timeline. If he didn’t drive, how did he leave? Did he live within walking distance, but then why drive?
Another thing - According to the ISP Press Release the girls were murdered within minutes of Libby’s audio, but then why was the car apparently parked there until 5pm? By 5pm family members had already arrived and began searching iirc and the girls disappearance was reported at 5:30pm. Was he watching from a distance as their concern heightened? Absolutely disgusting to even contemplate...
My thinking after the presser is that there is a higher degree of likelihood he drove himself to the area than maybe was thought two years ago. I thought he was likely a transient without a car, but this latest presser has me rethinking.
