Dunno if you monitor this account, but the man on the far left is Decoy Octopus. He played as the DARPA Chief (Donald Anderson) when you first encounter him in his cell alive. Due to complications with the FOXDIE virus, he died under the disguise of the DARPA Chief.



When you succumb to the torture methods of Ocelot later in the game, you find yourself in a cell with the rotting corpse of the actual DARPA Chief (Donald Anderson). During the first cell sequence, the guy dying is Decoy Octopus, and this is meant to be implied. You never see him in his true form in the game, but you're supposed to know that he was a decoy when you find maggots on the actual DARPA Chief's body in the cell after the torture.
