Apparently, President Kaler has gotten tired of answering letters from Leigh Turner about the death of Dan Markingson. He has turned the job over to William Donohue, Mark Rotenberg's replacement as General Counsel. In fact, however, it doesn't really matter much who signs these letters. They all say the same thing. Which is some version of: "We won't discuss the case or argue with you about it; you'll just have to trust us when we say we've been exonerated."
And yet, once you've seen several dozen of these statements, you start to notice the small differences. For example, Donohue has dropped the claim that the IRB investigated Markingson's death. (Presumably this is because the IRB never investigated.) He has also dropped the claim that the Office of the Attorney General investigated the death and cleared the U. (Presumably this is because of the recent letter by the Office of the Attorney General stating that this claim is untrue.)
But there are small additions too. Like Aaron Friedman, Donohue claims that the case was reviewed by the Office of the General Counsel. I'm not exactly certain what "review" he is referring to; the Office of the General Counsel is responsible for defending the university in court, not conducting independent reviews of research misconduct. But if the Office of the General Counsel conducted an independent review, as the letter implies, what did that review conclude and why has it not been made public?
