The business chief of the Russian state news agency Itar-Tass has been stabbed to death in his central Moscow apartment.
Authorities say 55-year-old Anatoli Voronin died of multiple knife wounds. Reuters news agency quotes prosecutors as saying police are looking at several possible murder scenarios, including a theory the killing may be linked to a personal dispute rather that his work.
The death is the latest in a spate of high-profile killings in Moscow in the past month. Acclaimed journalist Anna Politkovskaya was shot and killed in an apparent contract murder October 7. There have been no arrests.
Deputy Central Bank governor and anti-corruption advocate Andrei Kozolov and his driver were shot dead in Moscow on September 13.
A Moscow court Monday approved the detention of three suspects in that killing, which is widely thought to be connected to his anti-crime efforts.
