Kerri was one of the hundreds of spectators at the Fortune City Arena to watch the Terror Is Reality show. When the outbreak began, she tried to flee the stadium but was attacked by zombies and killed in the lobby. Her body is then feasted upon by the zombies.
There is a another woman sharing the same model as Kerri can also be found in the Arena, not too far from the first one.
In Dead Rising 2: Off the Record, there is a third "Kerri" that can be found in the Arena lobby. This additional Kerri replaces one of the employees in the lobby, making a total of 9 employee corpses stationed at the Arena (versus 10 in Dead Rising 2).
Her corpse is listed as "svr_kerri_corpse_attractor" in the game's files, which is where her name originates as it was never given in-game.
Kerri shares the same exact model as Tamara Stein, the only difference being the color of her outfit, which is blue instead of green.
