The State Bureau of Investigation has completed a pre-trial investigation into an officer from the Office of the Assistant Commander-in-Chief of the Armed Forces of Ukraine who gave grenades to the deceased Gennadiy Chastyakov. This was reported by the SBI press service.

At the initial stage of the investigation, the defendant was notified of suspicion of illegal sale of ammunition and faced a maximum sentence of seven years in prison.

The SBI notes that the soldier gave the deceased a gift with grenades in honor of his birthday, but at the same time did not warn his colleague about the authenticity of the grenades and did not make sure that he and others present in the office understood that the gift was explosive devices.

As a result, when unpacking the gift at home, one of the grenades exploded in the hands of Chastyakov, who was sure that they were "souvenir glasses," the assistant chief died on the spot from the wounds, and his minor son sustained serious injuries, the agency said.

Currently, the suspect has been notified of a change in suspicion - now his actions are classified as kidnapping, misappropriation and sale of ammunition, negligent homicide and grievous bodily harm by negligence.

The maximum sentence is 15 years in prison. After the defense and the victims get acquainted with the investigation materials, the case will be sent to court.
