Sergeant Cadet Josef Bublík ("Bioscop" group), wounded by many fragments, ended his life with a bullet from his own pistol. Source: "Assassination" by Michal Burian et al. But I think the postmortem photo represents Jozef Gabčík.
Jozef Gabčík 8 April 1912 – 18 June was a Slovak soldier in the Czechoslovak army involved in Operation Anthropoid, the assassination of acting Reichsprotektor (Reich-Protector) of Bohemia and Moravia, SS-Obergruppenführer Reinhard Heydrich.
