Schemy, a project of Radio Free Europe/Radio Liberty, has identified a Russian prison medic responsible for crimes against Ukrainian soldiers held at Penal Colony No. 10 in Mordovia. His cruelty was so extreme that Ukrainian prisoners nicknamed him “Dr. Evil.”

Journalists have gathered testimonies from more than 150 former captives who recognized “Dr. Evil” in photos and videos. He turned out to be 34-year-old Illia Sorokin, a father of two and employee at Medical Unit No. 13 of Russia’s Federal Penitentiary Service (FSVP). He had previously listed his workplace publicly on social media, visited occupied Crimea, and participated in 9 May parades wearing Soviet uniforms with a St. George ribbon.

Pavlo Afisov, a Ukrainian marine from the 36th Brigade, said that Sorokin used a stun gun, forced Ukrainian prisoners to crawl, jump, and sing Russian songs.

“He derived aesthetic pleasure from seeing you bent over in front of him, hands raised, with nothing on you, eyes closed. Yet he would kick you between the legs, hit you in the gut, strike your liver, beat you with a rubber baton and a stun gun. He even said that people like us deserve genocide,” the soldier recalled. 

Another soldier, Oleksandr Savov, confirmed the abuse and the denial of medical care. Sorokin was approached concerning the mental health of Ukrainian prisoner, Volodymyr Yukhymenko, who was brutally beaten and later died. A Ukrainian forensic examination found multiple fractures, hemorrhages, and pneumonia.

Despite Sorokin’s denials of responsibility, Tetiana Zhuravliova, a personnel officer at Medical Unit No. 13, confirmed his involvement. She said that Sorokin is currently serving in the Russian army, using the callsign “Doctor” and collecting supplies, equipment, medicine, and camouflage nets for his unit.
