Tijuana, Baja California
Nothing is known about Ramiro's life before the outbreak, except that he lived in Tijuana, Baja California and was the leader of his gang, consisting mostly of his cousins. He did not get along with the Los Hermanos, a rival gang in Tijuana.
Ramiro is at the supermarket discussing plans with Marco to attack and seize La Colonia, after establishing a new alliance between both of their gangs.
Ramiro and his gang join Marco and his thugs and break into La Colonia, quickly moving through "the wall" and through the bus into the settlement. They find it abandoned and begin shooting their guns in celebration. However, they investigate "the wall" once they hear the bus starting and witness the zombies moving towards the town. They attempt to shoot as many zombies as possible before retreating towards the market. The zombie horde proves too much as Ramiro and the rest of the gang are attacked and killed, with everyone reanimating.
