Unfortunately for Danko it was not his cell door, but the one across from his own cell, a new prisoner was being isolated. Outside the Guards having just finished throwing some poor fool into his own cell looked over to Danko's cell, knowing he was subject to termination. Being the charitable soldiers they were they walked over to the Cell's controls, specifically the Life-Support system for the individual cell.
The first guard tinkered with the heating controls while the other guard made sure that the ventilation ducts that led into the room were sealed, aside from the ones pumping heat into the room. As they turned it up higher and higher Danko eventually noticed that it was getting balmy within the room, after ten minutes it felt like he was in 40 degree Celcius weather...An hour later he was feeling lightheaded due to a lack of water Danko was forced to lay on his back, nolonger having the energy to lift himself up due to weakness of lack of sustenance.
Within three hours he barely had enough energy to remain conscious, eventually slipping into a coma, from there on the temperature got too hot for his body to handle and in essence started to cook, even unconcious his body twitched and low moans of pain could be heard as his body started cooking in the intense heat.
Not much later his body expired, charred and burned severely all over the body, barely recognized as human anymore, yet the heat kept cooking the body while rising. Soon his body would be nothing more than ashes and charred bones...
