It was Carlos Harvey (Los (Roc9) who was one the snitches on the DMV case.
He signed a full "Cooperation Agreement" with the Feds.
He gave them access directly to his Telegram in real time for individual conversations and access to any boards he was on.  So they were able to stay on the board during the whole investigation.
He went with NSN and No Dayz Off down to a show (black dog's first) in NC that Shy was hosting and was texting in real time with the Feds everywhere they stopped and every turn they made to take them to the spot.  The Feds weren't there, they just documented everything based off of his surveillance equipment. 
He was wearing a camera in his shirt and a microphone in his watch to document the area, people, and complete show.  He gave license plates of cars he thought they could use.
He also called different people on regular phone calls with his phone tapped and asking questions about dogs, shows, and any information he could use.  He was also willing to set up shows to get his co defendants arrested.

Laron West (Frog (Get Sick) signed a plea agreement but since then he has agreed to work with the Feds.  He is giving them information on the DMV case as well as any information on other investigations that are pending.

Also some dude named Travon Jamaal Williams from the Portsmouth, VA area. 
He was picked up on the TL credit card case but not for dogs.  The state was already looking at Travon for dogfighting and the Feds took it over and made him a Confidential Informant.
I don't know who he is or what he goes by.  investigation still ongoing!!!!
