The investigation is still ongoing. From what I heard, the feds are supposedly involved. Kero also refuses to cooperate with officers and has been moving back and forth between New York and Pennsylvania.
The only significant developments so far is Snakething, CoreyTWC, Woof getting arrested. Corey was charged with animal abuse and obscenity and he is awaiting trial.
Woof was unfortunately let go. Cuba has no animal abuse laws but I'm surprised they didn't charge him with disturbing and creating pornography. Though, there's a group of animal rights vigilantes in Cuba fighting for justice and using his case to get the government to create laws against animal abuse.
Snakething was let go too, but only because law enforcement wanted to charge him with CP charges too. He was originally just charged for animal abuse.
