Nothing is known about the guard's life prior to or as the outbreak began. He most likely lived near or in Richmond.
After the apocalypse started, he found Richmond and became a guard for The New Frontier.
The guard is patrolling the hallways near the armory when Gabe jumps him. The guard tackles Gabe until Javier comes. The guard is able to stab Javier before being knocked out by him. He is put in the locker by Javier and Gabe so no one sees him.
When Javier is on the rooftops, he hears walkers and looks down to see the guard unsuccessfully fending off a group of walkers and being devoured.
When Kate's armored truck exploded, a herd of walkers came pouring in, leading to this man being devoured.
It is unknown if there was anything left for him to reanimate.
- This guard was originally supposed to be a spanish-speaking engineer that Javi could use his (originally planned) bilingual skills to communicate with.
