On Thursday a Russian court found lawyer Sergei Magnitsky guilty of tax evasion.
The verdict comes more than three years after Magnitsky died in jail, awaiting trial.
Magnitsky was jailed after accusing police and tax officials of multimillion-dollar tax fraud.
He himself was then charged with tax evasion and fraud.
Magnitsky's trial is the first time a dead man has been tried in Russia, in a case human rights groups say is politically motivated.
The Kremlin's own human rights council said evidence suggests Magnitsky was beaten to death, but Russian President Vladimir Putin has dismissed the allegations.
No one has been held criminally responsible for Magnitsky's death, underlining the dangers faced by Russians who challenge the authorities.
