The investigation into the murder of former State Duma deputy Denis Voronenkov is almost over now, deputy prosecutor general of Ukraine Yevhen Yenin has said.

"It is actually solved, and as soon as the interests of the investigation allow it, the results will be open to the public. I can only say that the murder was put the lid on. The key things are already known to the investigation," Yenin told the Insider edition published on Monday.

As reported, former Russian State Duma parliamentarian Voronenkov was murdered in central Kyiv on March 23. Murderer Pavlo Parshov was injured by the ex-deputy's security guard and died later in hospital.

Voronenkov's murderer had an accomplice Yaroslav Levenets, who has been wanted for economic crimes since 2012. Tarasenko is suspected of committing a crime pursuant to the article of the Ukrainian Criminal Code dealing with premeditated murder. He was detained on June 16.
