A woman who worked on the building of the Enterprise-D at Utopia Planitia and was murdered there by Walter Pierce, a crime uncovered only in 2370.
Marla Finn was a member of the team that built the USS Enterprise-D. She figures in the episode Eye of the Beholder, where she is seen in Deanna Troi's visions.
Finn was involved with a colleague, William Hodges. A third worker, Walter Pierce, was jealous. He found them together in a nacelle control room, killed them both and then destroyed himself in the plasma stream. Their remains were sealed inside a bulkhead and all three were recorded as missing.
Pierce was part Betazoid, and his last moments left an empathic mark on the room. Eight years later it drives Lieutenant Kwan to his death and nearly does the same to Troi. In her hallucination Troi keeps seeing a frightened woman's face, which is Finn's. Bone fragments found behind the wall confirm the story.
