Marla E. Finn was a Starfleet ensign (serial number: CU-461-095), a Human native of Mars, the daughter of Ellen and William R. Finn. Her birth was recorded as med file #EP-301-2, and she graduated Starfleet Academy in San Francisco on stardate 40591.5.
She had an average efficiency rating of 8.9, and was a specialist rating 2 in warp field stabilizers. She received the Jalhal Award for warp field studies on stardate 40632.7, when she was assigned to USS Silversides.
After serving aboard Silversides, Finn was assigned to Utopia Planitia Fleet Yards. There she assisted in the warp engine local control systems installation aboard the USS Enterprise-D, during its construction in 2362.
During this time, she became romantically involved with Walter Pierce, but also had an affair with William Hodges. All three went missing; Starfleet noted her disappearance from Utopia Planitia on stardate 40987.2, but the Starfleet OSHC investigation ended without result on stardate 40999.4, the year prior to the ship's launch.
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")
