Partridge fits all of the clues that the blind woman left even the same voice, he faked his death we never saw him after that appearence and with the Tygers inside the cbi fbi it wouldnt be hard to fake it and I also think that he is Bret Stiles' son, thats the only way he could have such a power even in Mexico and we all know that Stiles has friends all over the world. Partridge also appeared on every season at least once if Im not wrong so everything fits, he with the help of the tygertygers and visualize.
For the guys with the tattoo I think they clearly ARE NOT Red John but they are part of the Tyger Tyger and thats like their insignia, im not sure they are disciples of RJ or just a bunch of cops helping each other to catch the biggest serial killer ever, anyway there is sth about Kirkland's twin broder I am sure he killed that suspect but if thats so maybe he just joined Visualize and turned a killer with Stiles leading him, Patrick never investigate or asked Stiles about the address he gave him and how the hell could he know? 
Another thing, in the promo for 6x07 we can see that after the shot in PJ house we can notice a flashlight, and Jane make the 3 suspects with the tattoo get on a white wall, maybe he took a picture of them with the tattoo and left it to lisbon for searching about those three because we also saw behind Rigsby the picture of Sheriff Thomas.

So many questions will be answered this month I can't wait! your thoughts?

PARTRIDGE OR MICHAEL KIRKLAND.
