Marla Mapes

Marla Maples was a woman who chased to the roof of the office building she worked at by a horde of zombies. She was bitten by one of them in the process. UBCS members Carlos Olivera, Nicholai Ginovaef and Yuri Loginova came to her rescue, but Marla, knowing that she was infected from the bite and would soon turn into a zombie herself, jumped to her death from the skyscraper's roof.

Trivia
In a deleted scene included on the DVD, Marla is shown to be a co-worker of Angus Mackenzie, who joins her in running from the zombies but ultimately leaves her behind.
