A judge in several high-profile cases was gunned down Monday as he walked out of his apartment to go to work, officials said.
Eduard Chuvashov had worked as a judge with Moscow's City Court for two years.
He specialized in handling complicated criminal cases and felonies, said court spokeswoman Anna Usacheva.
"We knew him as a very professional, decent and responsive person," Usacheva said.
In December 2008, Chuvashov sentenced a group of Russian teenage skinheads for carrying out 20 racially-motivated killings.
Seven defendants were handed prison sentences ranging from six to 20 years for killing non-Slavic migrants in Russia between 2006 and 2007.
When arrested, the leader of the gang, Artur Ryno, was only 17. The gang posted videos of their attacks on the Internet, readily admitted to their crimes in court and didn't repent.
Most recently, Chuvashov convicted 12 skinheads from a group known as the The White Wolves.
Russia's Interfax news agency quoted an official as saying the judge had been getting constant threats, and ultra-nationalist groups had urged their followers on Web posts to lynch the judge.
