Marla E. Finn was a Starfleet ensign (serial number: CU-461-095). She was promoted to her rank on stardate 38592.6. She was a specialist (grade 2) in warp field stabilization systems. She had an average efficiency/coind rating of 8.9.
She had graduated from Starfleet Academy in San Francisco on stardate 39591.5. She was assigned to the USS Silversides on stardate 40632.7. She was awarded the J-Lee Award in warp field engineering on stardate 40937.2.
In 2362, after serving aboard Silversides, she was serving at the Utopia Planitia Shipyards, Sol system, as a warp field containment engineer. She was a junior technician on the warp engine local control systems installation.
During this time, she became romantically involved with Walter Pierce, but also had an affair with William Hodges. All three went missing; the shipyard reported her missing on stardate 40987.2 and the Starfleet OSHC investigation terminated without result on stardate 40999.4. The case went cold.
It was not learned until late-2370 that she and her male friend had been killed by Pierce, who had caused a plasma explosion out of jealousy and then threw himself into the plasma stream. (TNG: "Eye of the Beholder")
