Almost nothing is known about Julio's life before or as the outbreak began, except that he received mechanical skills at some point in his life.
Julio is quarantined in Cell Block A and witnesses a fellow survivor die. He stands next to Jeanette and is told by Hershel Greene to return to his cell as he deals with the dead man. Later, he watches in horror as Hershel is attacked by a woman who died from the flu and reanimated into a zombie. As the situation unfolds, he closes and locks his cell.
Julio runs out into the prison yard with the other survivors after the Governor destroyed one of the guard towers with his tank. As Rick negotiates with the Governor, Daryl hands Julio a sniper rifle to help defend the prison. When the gunfire begins, he flips a table for cover and shoots at the Governor's milita, killing at least one man. As the remaining residents evacuate from the prison, Julio turns to join them in the run for the bus. However, he was shot in the back and killed, just a few feet away from Maggie and Glenn, most likely saving their lives by being in the way and taking the bullet.
When Julio is shooting at the Governor's people during the prison battle, he attempts to escape with Maggie and Glenn, but ends up getting shot in the back by one of the Governor's militia. It is unknown if he reanimated or if he was put down.
This list shows the victims Julio has killed:
- The name Julio is not used in any dialogue or credits, but it was the name given to Santiago Cirilo for his role.
- During the Talking Dead "In Memoriam", Julio is mistakenly shown dying under "The Governor's Militia".
