A professor of history and political science from the Moscow University for the Humanities stabbed himself to death at his home in the northeast of Moscow.
Police believe that the professor stabbed himself in the chest with a dagger that was given to him as a gift, a police spokesperson told RIA-Novosti on Wednesday.
His wife reported finding him Tuesday morning with two wounds in the area of his heart, Interfax reported, citing a source in law enforcement.
"The door to the apartment was locked from the inside, so it is likely that the professor stabbed himself twice in the chest with the dagger. It was discovered on the bedside table next to his body," the source said.
His wife told police her husband had been depressed lately and on the eve of the incident had returned home from the university very upset.
The professor, Vladimir Krivoruchenko, was 82 years old.
