Not much is known about Clint except that he was a pipe-fitter from Augusta.
Clint was a Woodbury resident, and participated in the prison assault. Clint survives until the second assault on the prison, as they breach the gates and get inside the prison. After Lilly kills the Governor, walkers overrun the survivors and Clint is bitten by a walker that latches onto his neck, and is quickly devoured. As Clint falls, it opens the eyes of the other soldiers, causing them to be more aware of their surroundings.
Clint is bitten by a male walker when walkers overrun the survivors, the walker latches onto his neck and burrows into the haemorrhaging nerve bundle and then is devoured by more advancing walkers.
