Dateline also just reported that a classmate of BK at Pullman had someone break into her apartment and not take anything, but move things around. She didn't report it to LE because nothing was taken. But she did call BK and he offered to go over to her apartment and have a look. He recommended she install a video security system and he offered to install it. So she did, and he did install it. And he knew the password, since he installed it. Just an interesting fact they reported, since Dateline is looking at the possibility that the murders followed a progression of actions by BK.
Also, in Moscow, close to the King Road House, about a month or so before (IIRC) a student who lived in a sorority nearby reported that she had left a suitcase in her car overnight, and in the morning the suitcase was found outside of her car. And stuff she had in her car in the center console, etc. were now in the suitcase. And a piece of her underwear that had been in her suitcase was placed in a cubby area of her side door console. Creepy and weird, police came and took a report, agreed it was weird. No proof this was related to BK, but they wonder if BK was progressing toward the murders by taking steps of peeping, doing odd things.
Now they wonder if BK was involved in some of these reports around the time before the murders and in the area.
