yesterday was very interesting.

There was text found in tiny print within the note about the dog. It said:
IFYOUCANFINDHIMATALLSTROUDLIKESBIGBOOMS
and also had the entire "born of black and white" riddle. It is therefore possible that Billy/Billos is on the inside with black giving us these clues. Only billy knows the riddle and could put it in the message so we would notice it. Stroud is an unknown character so far, but could be the arsonist who blew up the library building. There was an accelerant involved in that fire.
DA set up a meeting with Kamenski in Vegas, but Kamenski was to meet Black and some accomplice, now thought to be Billy/billos, before he met DA and would not heed our warnings. DA was delayed when the plane landing gear was broken by running into a deer. He would be unable to get there until 2:45 Mountain time. Here is David's comments when he saw Kamenski's dead body:

I only have a min. Police taking me into custody for questioning. My attorney is en route.
I landed in LV @ 2:45 local and took a cab to Kamenski's place. 3:20p or so walked into his office. Still can't believe what I saw. He was already dead. His body was on a table in the middle of the room--in a kneeling position, like he was praying, hands tied behind him. Head back, mouth open. Totally unnatural position. The word "SINNER" was painted on his chest in red.
Then I saw that his eyes were...gone. No blood. They just weren't there.
A note had been rolled up and put in his mouth. I opened it. It read:
"Nothing in his life
Became him like the leaving it.
See you on the flip side, baby."
Then the police arrived. I have to go. I am safe, but it looks like I was set up. Will talk soon. DA

This note is quoting Macbeth. The body was found in a way similar to the victims of both black and red, and since we saw the axe in House the characterizations of White are showing up in the persona of Black. He now acts like all of them. The last thing that is important is that a J. of Southern could be a character or just someone trying to impersonate a NPC. For example, one person was found out to be a fake last night.

Today DA's post is interesting too. Here it is again:

Thanks for everyone's concern for me. After a couple hours of questioning, LVPD released me. I am not being charged in the Kamenski case. My thanks to the Overseer and the legal counsel he sent to my aid. The Circle is everywhere...even in Sin City, believe it or not.
I spoke with both the Overseer and Kara late last night. We are obviously not alone in our search for the Book. Now it is an all out sprint between us and Black. One thing I know for certain: he is not working alone. But, I can't be certain who his accomplice is or what threat he/she might pose to us.
We have to move quickly, but safely. As you may already know, the Overseer thought it best to upgrade the security & monitoring software on the message boards as a precaution. You may have noticed a brief unavailability this morning.
I am en route to follow up on another lead; this time in VA. Hopefully, I'll have something to report soon.
Friends, we need many more eyes looking for the Book than we have right now. I desperately need your help. We MUST recruit more people for the Circle if we are going to succeed. We will overwhelm Black with sheer numbers, if that's what it takes. He can't be everywhere at once. But, we can with enough help.
You will be contacted soon with a mission to strengthen our ranks. There will be a reward involved, obviously. I'm asking for your help. I need your help. Once the Overseer contacts you, please respond in force. Much more may depend on this than we know.
Peace,
DA

This reveals much about the format of the game, which now seems to be going on and the timer is counting down to somthing else. So many people think the contest is not already started, and they will need a thing like this blog to keep up with what is going on.
Happy to help.
