|“||It's a prison bus, asshole. The windows don't open.||„|
|~ Marcus Crabtree to Jerry.|
He was a criminal. Two days into the apocalypse he was being transferred on a prison bus. While he was in there he had a heated argument with another prisoner, Jerry. The two fought so much that Crabtree began to strangle Jerry with his cuffs. He didn't even stop after a prison guard named Clyde pointed a shotgun at his face. He managed to strangle him to the point Jerry died. The guard however blasted Crabtree with the gun and he died instantly.
He is the responsible of the events in prison bus. After he kills Jerry, Clyde killed Crabtree. Later, zombies came to the prison bus and Jerry reanimated and attempted to kill Vince, Danny and Justin. Eventually, Vince shoots Danny/Justin to the save the rest of them.
