Former Soviet spy Leonid Shebarshin, who was head of the KGB for one day on August 22, 1991, and then retired a month later, was found dead in his apartment Friday. There was a suicide note.
Here are some quotes from the comments below the article. I haven't checked any of this out, by the way:
He was the head of KGB for one day after the attempt of antidemocratic putsch in which he refused to participate while the head of KGB did and lost his position. Before the putch Shebarshin was a the head of the spy division, and became interim KGB chief after the events. But he did not stay in this position and very soon resigned from KGB because he did not agree with the policies of the new leadership. He comitted suicide because he was old, very sick and recently lost his vision 100% and he did not want to live as a helpless old man.
After he resigned from KGB, he founded a company that conducted private investigation of economic crimes and corruption.
