MOSCOW, January 26 (RAPSI) – An investigation into the murder of Russian opposition politician Boris Nemstov has been completed, Musa Khadisov, a lawyer for one of the suspects in the killing, told RAPSI on Tuesday.

After all the suspects get acquanted with case materials, they would be forwarded to the prosecutor's office for indictment, Khadisov said.

Nemtsov, 55, was murdered in central Moscow as he walked across a bridge near the Kremlin on February 28, 2015.

Five suspects were detained in the case, including the suspected trigger man Zaur Dadayev. He initially confessed to the killing but later said in court that he made the admission under pressure.

In December, police named the alleged mastermind behind the high-profile murder, Ruslan Mukhudinov, a former officer in Chechen Interior Ministry.

Mukhudinov was added to a federal wanted list and placed on an international wanted list. He fled Russia using a fake passport, according to investigators.

Vadim Prokhorov, a lawyer for the Nemtsov family, said that Mukhudinov was unable to have masterminded the murder.
