Tiger Tiger burning bright
In the forest of the night
what immortal hand or eye
could frame thy fearful symmetry
The Tiger is Red John.
And then... further on..
When the stars threw down their spears
And wat'rd heaven with their tears
Did he smile His work to see?
Did he who made the lamb make thee?
There's more to the poem of course... But... The last line is telling. The "lamb" is the cult, Visualize. It offers techniques against rage and aggression, and is against things like brainwashing, a fairly peaceful cult.
The poem basically is about god's creation of the fearsome, deadly heart of the tiger, and marvels at how god could have created such a wicked, evil creature, while also creating the gentle lamb. In this case, "god" is not an immortal being, but rather, the creator of Visualize, Bret Stiles.
So, who is the Tiger? A rogue member of visualize. Ray Haffner is a confirmed member of Visualize. Unless someone else has been a member of visualize, he is the only one that fits the riddle of this poem. .
Next, we have the line... "Red John Likes the Cold"
This is likely a riddle as well.
It may be hinting that Red John's name is the same as some place that's very cold. If that's so, then, there's a place in Canada called "Haffner Creek". It's an ice climbing site. I couldn't find anything similar for the other suspects.
Finally, Ray Haffner also fits much of Red John's profile, without being completely obvious.
