(Covers information from Anderson's universe)
During the widespread panic to escape the city, Marla attempted to escape from a horde of Undead that chased her into the stairway of the office building where she worked. In a panic, she forgot the code to the door that would let her out onto the roof. Unfortunately, she was bitten by one of the Undead on her arm and infected with the t-Virus the moment she remembered the correct code.
Umbrella Biohazard Countermeasure Service members Carlos Olivera, Nicholai Ginovaef and Yuri Loginova came to her rescue. But Marla, knowing that she was infected from the bite and would eventually turn into an Undead, decided to commit suicide and jumped to her death.
- Marla was a co-worker of Angus Mackenzie. In a deleted scene, she is seen fleeing with Angus, but is soon abandoned by him in the panic. This was cut from the film, but her scene was retained.
