Palmer Son 1 (Webisodes)

The Palmer Children were the kids of Mike and Maggie Palmer who lived together in Andrew's neighborhood.

Pre-Apocalypse
Not much is known about the Palmer kids before the apocalypse, but we can assume their father, Mike, did the best he could to protect them. The family and children were having a surprise party for their father when the apocalypse began.

Post-Apocalypse
Walkers attack the party, presumably killing the guests and the children were bitten and infected. Palmer was forced to flee where he locked them outside or locked himself in the cellar to prevent them from biting anyone or himself. During the struggle, it seems that Mike is injured in the leg. Later, in the basement, Palmer shows Andrew his wound and tells him to kill him.

A while later when Andrew, Hannah, Jamie, and Billy are going to try and escape with Palmer's truck, not knowing how to hot-wire a truck, Andrew goes into the basement of Palmer's house looking for the keys. Andrew is killed and eaten by the children.

This is the last we see of them, but they are probably still roaming around the town, looking for a fresh kill.

Killed By
Mike Palmer's children were possibly bitten sometime during Hannah's car crash and later turned. Mike never shot them, instead he killed himself in the basement.
 * Unknown, possibly bitten.
