Mark (The Beta)

Mark (The Beta) was the second person infected by the virus, making him second-in-command to Jack. Later on in the story, he grows to pity the humans, even going so far as to assist them.

Pre-Infection
Not much is known about Mark before the outbreak. He was attending a high school party the night the outbreak occurred, and it can be assumed that he attended high school somewhere in Oregon. He was also a junior in high school, and had an older sister named Heather.

Post-Infection
While washing his hands in the bathroom, Mark was tripped and infected by Jack. The two then began infecting random people, eventually claiming every person at the party.

Killed By
While the two of them were fighting, Jack managed to blind Mark, eviscerate him, and throw him off the roof of a building.
