The investigation into the murder of Russian investigative journalist Anna Politkovskaya will be prolonged until February 2011, a spokesman for Russia's investigative committee said on Wednesday
Investigators have established new suspects in the case, Vladimir Markin said.
Novaya Gazeta reporter Politkovskaya, who gained international recognition for her reporting of atrocities against civilians in the troubled North Caucasus republic of Chechnya, was gunned down in an elevator in her Moscow apartment building on October 7, 2006.
"Investigators are going to extend the probe until February 2011," Markin said.
In February, a Moscow court acquitted three men charged with involvement in the shooting of Politkovskaya, but the Supreme Court overturned the ruling and ordered a retrial.
Then President Vladimir Putin said that the killing, which took place on his birthday, had been carried out by forces seeking to "create a wave of anti-Russian sentiment in the world."
Russia is one of the most dangerous countries for reporters. The Committee to Protect Journalists said in a recent report there had been 17 killings since 2000, and just one has been solved.
