I can definitively rule out the Mentalist Jane as “Red John” as he could not have poisoned somebody in a uniform and then 30 seconds returned from a distance and a staircase, in a suit, to tell then not to touch her. Physics rules. But, this still points to Minelli as the “uniform” that past by was a heavy armed individual that she looked up to slightly, not so much taller than herself, as is Minelli was only an inch or so taller than Lisbon, who seemed to be the same height as the “Red John” Secretary/Lover.
