Former Ukrainian marine Yaroslav Rumyantsev showed a photograph of himself when he was held in Russian captivity, Japan Times reported. " A young Ukrainian lieutenant talked back too much, prompting Russian jailers to beat him to a pulp. He was left with extensive injuries and bruising that festered on his buttocks and the backs of his thighs, according to Alexei, a medic in the Russian prison infirmary.

The young Ukrainian lieutenant was denied proper care. His body became gangrenous and he died in October 2022, Japan Times reported. Alexei said the young Ukrainian lieutenant's body was likely buried in an unmarked grave.

The former medic was never able to find out the name of the young Ukrainian lieutenant. Rumyantsev's photograph and Alexei's account surface as reports continue to emerge from Russian detention sites holding Ukrainian prisoners. Japan Times reported on the cases from Warsaw on May 12, 2026.

Alexei, who worked in the prison infirmary, provided the details of the lieutenant's treatment and death. The former medic's description adds to accounts from former prisoners detailing physical abuse and lack of medical attention. The young Ukrainian lieutenant's injuries went untreated after the beating.

Gangrene set in as a direct result of the festering bruising and denied care, leading to his death that October. Former prisoners have recounted similar patterns of abuse aimed at breaking detainees. Families of those still held have echoed descriptions of systematic mistreatment inside the jails.

Rumyantsev's decision to display the photograph brings a personal dimension to the broader pattern of captivity experiences. His image from captivity stands as one of the few direct visual references available from inside the facilities. Alexei's inability to learn even the lieutenant's name underscores the anonymity that often surrounded deaths in these prisons.

The former medic's account ends with the unmarked grave, closing one more case without formal record.
