I left a message at Superintendant Tobacks's office and am waiting for a call back now.
Meanwhile, with regard to current custody of the '2-color' letter, Mitchell provided this:
So the question of why a 2-color letter was given out is out there, while the letter may be back where it belongs- in Superintendant Toback's office.I saw (redacted) walk over and talk to Toback, and at the Diner, (redacted) said she gave the letter to Toback. I did not see her hand it to him.
At the Diner, I asked (redacted) if she had the copy with the blue signature. I said there was one original. She said "I gave it to Dr. Toback."
Will post any updates that come in.
