The following is a list of Tarsus IV inhabitants.


R. Wiegand was a named inhabitant of Tarsus IV who was referenced in the final revised draft script of TOS: "The Conscience of the King", but not in the final version of the episode. He or she may still be among the unnamed murdered eyewitnesses.
A portion of Hoshi Sato's biographical data created for, but not used in, the Star Trek: Enterprise episode "In a Mirror, Darkly, Part II" stated that she and her family were among four thousand people who were killed by Kodos. This might include Takashi Kimura, established as her husband in the graphic.
A bio for Khan Noonien Singh's alias "John Harrison" prepared for Star Trek stated that he was one of nine survivors of the massacre in the alternate reality, both parents (Richard and Sara) having died.


Massacre survivors

These survivors were among the four thousand (half the population) not murdered by Kodos in 2246. Some of them were children at the time, and watched their parents die.

Of those survivors, there were nine witnesses who who would have been able to identify Kodos visually, of which four unidentified witnesses were murdered sometime before 2266 by Lenore Karidian to keep them from testifying. Before they could be listed by the USS Enterprise's computer, James T. Kirk interrupted it upon hearing Kevin Riley's name on said list. (TOS: "The Conscience of the King")

These people were only mentioned in dialogue.

Massacre victims

These victims were murdered by Kodos in 2246. They were chosen based on Kodos' own theories of eugenics. Though their deaths were physically painless, they were nonetheless traumatizing to those left behind. (TOS: "The Conscience of the King")

These people were only mentioned in dialogue. In the final revised draft of the script for "The Conscience of the King", these four thousand victims were referred to as including "men, women and children," who were "forced into an antimatter chamber" where they were exterminated all at once.
A deleted scene from the episode revealed that Thomas Leighton's parents and two brothers were among the dead, the deaths of which continued to give Leighton nightmares.

Kevin Riley's parents

The parents of Kevin Riley were inhabitants of Tarsus IV in 2246, when they were sentenced to death by the colony's governor, Kodos. Riley was haunted by the events, and decided to avenge his parents' deaths when Kodos (disguised as Anton Karidian) visited the USS Enterprise in 2266. (TOS: "The Conscience of the King")

These people were only mentioned in dialogue.
"Who's Who in Star Trek 2" gives their names as Joan and Thomas Riley.

Burned body

This burned dead body was found by responding Earth Forces in 2246 and believed to be that of Kodos himself, though no positive ID was made at the time. (TOS: "The Conscience of the King")
