IMO, @Chloegirl, you are onto something.
I think BK could have done all of the above, including:
Creepy crazy kind of stuff for an everyday sort of person to do, IMO, but not beyond the realm of possibility for someone like him.
- DNA testing to identify his own signature and potentially those of others and see which methods worked best at erasing DNA/leaving unidentifiable traces of DNA.
- Blood testing for same/similar reasons as DNA.
- Luminol testing to see to what degree blood might soak through things like Tyvek booties, etc. (in regards to things like the "latent" footprint outside DM's room that was only seen through use of luminol, IIRC).
IIRC (as documented in MSM, and linked in the Media Only thread):
MOO
- When he was arrested in PA in the middle of the night at his parents'/his home LE found color coded ziploc baggies he was sorting his personal trash into in the kitchen. What a bizarre thing for him to be doing if he wasn't practicing at studying and controlling "release" of his DNA into the trash. And he was observed by LE before his arrest disposing of trash in the middle of the night in their neighbor's trash cans.
- His neighbors in the apartment complex in Pullman said he was often up all night running appliances and showering and making noises that woke them up. IMO, he could have been practicing then and there as well, at controlling release of his DNA onto this that or the other surfaces.
Well that sure is interesting to hear because I thought I was losing it. Suppose if you are OCD and fascinated by crime scene investigation, maybe. It's just another level. JMOO
