It is not a rumor, it is only a report on what SA Dorwin Schreuder told me.
Now, what exactly did Dorwin mean when he told me about finding a part of a cloth briefcase? Was is a false memory? He did say that his memory might be off because of his age, but he never displayed any faulty thinking in the rest of our interview or in later conversations.
Was his comment about his memory and age just a clever way to "walk back" a truth that no one is supposed to know about publicly? Maybe.
Or was it a true "senior moment?" Maybe.
Was Dorwin absolutely truthful with Georger a few years ago when G quizzed D on the briefcase and other matters pertaining to T-Bar and D said that there was no briefcase? Maybe.
But consider this: Dorwin is a super nice guy. He's the only FBI agent to invite me to his house. He spoke at length on multiple occasions about T-Bar and our conversations are what I would consider "normal." Most of my discussions/interviews with other FBI agents are stilted, scripted, or done in a guarded manner.
Also, Dorwin's grandson has written a story about Dorwin's career as an FBI agent. It's over 400 pages and only one page deals with T-Bar and Cooper. Further, the grandson writes that Dorwin left the FBI shortly after his stint in the Portland office, and he attributed D's departure as a response to the friction Dorwin had to deal with in the Portland office, most of which was triggered by Dorwin being the T-Bar PIO and then later taking over the Portland Norjak op from Himmelsbach when Ralph retired in 1980. The grandson also intimates that Dorwin had grown disenchanted with the Bureau, so retirement appeared very attractive.
So, read the tea leaves and make your own judgment. And as always - Georger, kiss my ass...
