I know she was disfigured in some odd way because KJ's partner's father said so. He said they could not view her. Also, local news radio mentioned that there was some sort of marking on her.
So..the FBI...there are only a few reasons they would be involved here.
-Local Police asked them to be involved (possible killer's DNA from Bowie's mouth?)
-Hate crime (could be but the community as a whole is pro LGBTQ and not at all unusual, lots of easier targets could have been chosen)
-Something very weird or bizarre about the crime..could have similarities to other weird crimes.
To me, could be #1, #2 maybe, what was the "marking", could be #3 or, 1&3.
Honestly, I think we can all feel something is weird.
The whole thing is just terrible. Killer has to be a super messed up person to do all of that and the dog, too.
