The March 9 edition of the Russian "Kommersant" daily quoted Andrei Slutu as identifying the suspect as Igor Velchev, a Moldovan citizen, and saying that Velchev had managed to escape arrest a few days ago by fleeing to Romania.
Slutu told the Moldovan news agency Flux on March 9 that he never made "such statements" for "Kommersant."
Zimin, a 33-year-old investigative reporter who worked with the NTV television station, was found dead in his Moscow apartment on February 26. Russian prosecutors say they believe his death is not connected to his work.
