Jada Marks was in Command of Talos I Flight Management as every shuttle was monitored by her as Captain of Talos I station. She was having a dilemma over whether to destroy Shuttle "Advent" as it departed 30 minutes from Talos I before the Typhon outbreak happened. However, the Typhon already got her before she could make her decision and she was killed by Mimics as heard in the TranScribe.
Her room on Crew Quarters stores the code on the vault that enables Morgan to obtain the Artemis Golden Pistol, the gun that was mentioned by one of her crew in order to use it against the Typhon.
Prey (2017) Edit
Morgan Yu finds Marks corpse in Captain's Loft. She carries lemon peel, TranScribe, keycard to her cabin and neuromod. A Silenced Pistol is laying near her corpse. Reading her emails opens up a side quest where Morgan Yu needs to decide whether to destroy Shuttle "Advent" with scuttle charges or let it land on the Seattle Facility, possibly bringing Mimics to Earth.
