"You could see by the blood trails, the shell casing, and pockmarks that the entire battle had originated from the infirmary,” Because of this, I know it was the infection.

At the end of the room we found a headless doctor, lying of the dirt floor next to a cot with soiled sheets and clothes and an old, left-footed , worn-out Nike high-top. The last tunnel we checked had collapsed from the use of a booby-trapped demolition charge. A hand was sticking out of the limestone, and was still moving.” The zombies escaped, and we know that they were not properly quarantined and will continue to infect other people.
