As I was typing this, I remembered something else. Upcoming speculation: Remember when that rumor went around that BF saw a naked man flee the house? What if BK undressed AFTER DM saw him? He could have gone to the house wearing nothing BUT coveralls, shoes, gloves and the mask. You could strip that off pretty quickly outside, jump into the car wearing underwear or nothing, and take off. I could totally see BK's attorneys claiming that meant there was someone else there, when it was really just a naked BK. MOOooo
If the perpetrator is very forensically aware, why wouldn't they have covered up and then strip down before entering their own vehicle? That wouldn't take long and certainly would explain sightings of any naked man. However, one would assume he'd do it outside of the house and also one would assume rather than looking like a naked person running somewhere, they'd look like a person quickly undressing then running and carrying a kit bag. He could have stashed himself a changing kit with a bag to seal the dirty clothes and shoes into, cleaning wipes, and a fresh outfit outside of the house but before his car. Or he could have simply peeled off some form of fairly water tight outfit.
