A couple of mentions, fwiw:
I thought the pix of smiley Casey on the left was taken for an I.D. badge when Yuri, et al, had her go to OCSD HQ for questioning before she was arrested. I recall remarks about the inappropriateness of her demeanor, not heeding the gravity of the situation, and acting like she was there on a guest visitor pass.
I had read the note in the article ref'd above about the executioner being paid, but it was always my understanding from other cases (states?) that there would be three such persons and not any one of them would know who pulled the lethal switch (chair), shot the weapon with a real bullet not blanks (firing squad), etc. Also, far more than one person is required to enact the execution routines by elecrocution and lethal injection.
