Sergio is wanted for assault and can be captured or killed depending on the player's choice.
Sergio can most often be found around Chuparosa, frequently loitering inside the cantina. He can also be encountered at the Tesoro Azul gang hideout in Multiplayer, and Fort Mercer in Singleplayer but he will be hostile unless the player is wearing the Bandito Outfit.
- Sergio's character model is available in the Outfitter under the name Alejandro Cruz.
- His name may be a reference to the famous Italian director Sergio Leone, the director of the Dollars Trilogy, as well as many other spaghetti westerns.
