Chef []
The chef was killed by Khan Noonien Singh when Khan discovered that the Genesis Device and related data were gone.
According to Clark Terrell, Khan tortured the remaining crew, including the chef, but no one would reveal to Khan what he sought. As a result, Khan went wild, strung them up and slit their throats.
Following the arrival of the USS Enterprise to Regula, the chef, as well as the other crew were discovered when Leonard McCoy unexpectedly walked into the chef's dangling arms.
As the murdered crew were lowered to the deck, McCoy assisted Admiral Kirk in laying the chef's corpse on the floor, during which he observed that his body was not warm, but noted that rigor hadn't set in. (Star Trek II: The Wrath of Khan)
