So, change of clothes.
- planning to be up all night and/or they were up for long periods of time wearing same clothing in days after the murder
- planning to get dirty and/or
- planning to need to change their appearance and/or don't need change of clothes for that, just layers. would need other accoutrements to change appearance
- planning to shift to some other millieu where different clothes will be needed Where could they be going that different clothes would be needed? We know they planned to steal the truck.
It's creepy and weird, but probably still not enough to say for sure that it's premeditation to harm IT. Thoughts?
