Nothing is known about Eisenberg's life before or as the apocalypse began. It is possible that he lived in or near Woodbury, Georgia.
This list shows the victims Eisenberg has killed.
- Possibly numerous counts of zombies and unnamed people.
- A member of Rick Grimes' group.
Eisenberg was killed during the raid on Woodbury by Rick's group, where he was shot and killed, but it is unknown who actually killed him. However, of the six unnamed Woodbury survivors killed in the raid, only survivors 4 and 11 died in Woodbury, while the others were shot while standing on the wall, and fell off, outside Woodbury. Because of this, it is most likely that Eisenberg is either survivor 4 or 11, and Bob Adams is the other. If so, he was killed either by Rick Grimes or Daryl Dixon. There is also the possibility that "Eisenberg" is Warren's second name. If this is the case, he was killed by Maggie Greene.
