On 29 January 2016 Vladimir Markin, official spokesman for the Investigative Committee, said that the investigation into the killing of Boris Nemtsov on 27 February 2015 had been completed. Vladimir Markin said five suspects from Chechnya were in detention and had been charged with carrying out the contract killing. As RFE/RL reports, Markin also said that the suspected mastermind of the killing, Ruslan Mukhudinov, who is a member of Chechen leader Ramzan Kadyrov’s security forces, is still at large. Earlier, on 21 January 2015, head of the Investigative Committee Aleksandr Bastrykin had announced that the murder had been 'fully solved.' However, RFE/RL reports, Boris Nemtsov's relatives, including his daughter Zhanna Nemtsova, and lawyers have 'expressed skepticism about the probe, insisting the killing must have been ordered by high-ranking Russian officials.'
