Garza

 is a 30-year old engineer and friend of Madison Li working in the lab in Rivet City. He is found early on in the Rivet City Science Lab. Due to a weak heart, Garza is prone to exhaustion while walking extended periods of time. During the quest, The Waters of Life, his heart is close to giving out. The Lone Wanderer is given the choice to give him 5 stimpacks, give him 3 Buffout, leave him behind, or just kill him. Whichever is chosen, Garza is not important to the story.

It should be noted, however, that if the Player gives up the Stimpaks, Garza will be able to pick up weapons and fight. The Buffout will cause him to say that he won't be of any use, while leaving him behind will make him wander about the room where the decision is made for the rest of the game.

Bugs

Although he usually appears to be neutral to the Super Mutants, one author found Garza being attacked by the Mutants and obviously killed (360). In another experience, Garza picked up a minigun at the camp and kept it for the rest of the game. (360 and PC) . He can also be a Super Mutant Captive that can be freed like a normal Captive.
 * During the escape from the Jefferson Memorial, Garza simply may not appear as part of your group. Check the Super Mutant camp for his body to see if he had died, previously, before The Waters of Life quest.
 * During the Escape from the Jefferson Memorial if you kill him even by accident Doctor Li may glitch and not follow you unless you carry his body, meaning you cannot complete the quest (PS3)
 * During the escape, Garza begins fleeing after the first set of ghouls, and continues to do so until killed (360).
