My opinion tells me that a maniac is hiding there...
There is no ND that unequivocally states that the target is a maniac (except for a survey specifically designed for this purpose).

Lizard, why Gur and Shaman with a slash?
At what point did they manage to establish a non-pair - I haven't seen that.
Gur is such a bulky figure that you can understand his side either through a survey or by looking at the remainder, finding all the others.
(or through an ND deduction, but such a deduction cannot be argued in the thread).
