Quote: "The suspect has been informed of the change in the previously served notice of suspicion. He is suspected of theft, embezzlement, and trafficking of ammunition, manslaughter due to negligence, and causing grievous bodily harm due to negligence... 

The statutory provisions provide for punishment in the form of imprisonment for up to 15 years."

Details: At the initial stage of the pre-trial investigation, Timchenko was served with a notice of suspicion of illegal ammunition trafficking. On that tragic day (6 November 2023), he presented Chastiakov hand grenades to celebrate his birthday. 

However, he did not warn his colleague that the grenades were live and did not make sure that he and others present in the office understood that he was giving Chastiakov live explosive devices as a gift, the SBI emphasised. 

As a result, when Chastiakov was unpacking the "gift" at home, one of the grenades exploded in his hands. The man believed they were souvenir shot glasses, the SBI noted. 

Chastiakov died from his injuries instantly, while his underage son suffered severe bodily harm. 

After the defence and the victims have been acquainted with the materials of the pre-trial investigation, the case will be referred to court.
