Agreed, I believe LE have a plethora of damning evidence that will be BK's undoing !
In no way (imo) would they arrest someone on a 'hunch', or anything close to that.
They have something BK cannot wiggle out of, or attempt to explain away :
- Bloody glove impression.
- Dropped hair from his curly, well-kept locks. (I think he thinks highly of his physical appearance !)
- Bloody sole impression from his shoes.(My .02 is that it was messy and he couldn't avoid tracking through their blood. )
- Dna under the victim's fingernails (best evidence imo as why would someone there feel the need to gouge his arm if he was just there at a 'party' ?).
- Phone pings or car gps showing he was at the home during the murders.
- Etc.
Unless there's an update or when the AA is released, I think it's possible he was
not one of the party goers invited to the house... and so his dna should not have been there ?
The surviving roommates will know if they recognize him and if he was ever there, as well.
Again my .02.
