In The Search for Spock, Kirk's son David Marcus gives his life on the Planet Genesis, after Captain Kruge orders his men to execute one of the three prisoners (David, Saavik, and Spock).
Is there any information, perhaps in the Extended Universe, as to how and when Carol Marcus learns of the circumstances of David's death?
Presumably, she would have been told initially by Starfleet that David likely perished aboard the USS Grissom, the science vessel that he and Saavik had transferred to, which was destroyed in orbit of Genesis by Kruge.
Kirk may have been unable to contact Carol directly during his three-month exile on Vulcan, and so perhaps Sarek or Saavik contacted her in the first instance regarding the truth. But this is just speculation on my part.
Any information would be appreciated.
