Nemtsov was shot on Feb. 27, 2015 as he walked along a bridge near the Kremlin. The killing was a harsh blow to Russians opposed to President Vladimir Putin, depriving them of a charismatic and energetic leader.
Activist Nataliya Gryaznyevich said at Sunday’s march that “Nemtsov was a very colorful political figure.” She said his death “left an empty hole in politics.”
An officer in the security forces of Chechnya’s Kremlin-backed leader Ramzan Kadyrov was convicted of firing the shots that killed Nemtsov and received a 20-year prison term. Four other men convicted of being involved in Nemtsov’s slaying received 11 to 19 years.
