We don't have much evidence to help us determine what occurred at the site formerly known as Columbus, Ohio - we've only recovered these CCTV stills so far and they were badly damaged by the radiation.

There are no first hand reports available and this may be the only evidence we find that will tell us exactly what happened prior to the total destruction of the city. The reports that we have received have been sketchy at best, including one rumor of the dead rising from the grave and feeding on the flesh of the living.

From the current evidence we can't rule out the possibility of some sort of madness taking hold of people and causing them to eat each other, but I'm not sure that we'll ever know the truth. We have a team at the site now looking for further evidence and we remain hopeful... but for now we can only wait, and hope that there is not a repeat incident.
