A Final Plan for Esteban

A Final Plan for Esteban is an unmarked quest

Detailed walkthrough
Private Morales asks the Courier to retrieve the corpse of Esteban Morales, her deceased husband. Heading south from Camp McCarran toward the map marker is one approach. The body can be found just northeast of the REPCONN Headquarters, and the Courier may be approached by an NCR trooper who offers some advice for retrieving the corpse. There are several options at this point, as the location is commonly guarded by Fiends and various traps.

Carry it to the nearby NCR troopers camped just northwest of where his corpse is found.

After recovering the body and returning with the news of her husband's demise to Pvt. Morales, Doctor Kemp at Camp McCarran will offer discounts on both his medical supplies and services.

Bugs

 * A non-player character may accidentally detonate the mines around the corpse, blowing Private Morales to pieces and not allowing the quest's completion.
 * Colonel Hsu doesn't always thank you for bringing the body back, after speaking to Pvt. Morales again.
 * Mines fail to appear around the corpse, while the tripwire shotgun and bear traps are still in place.
 * Sometimes Pvt. Christina Morales disappears from the McCarran Concourse Hall after you have started it. If you go to the body, there are no NCR Troopers around to take it to.
 * Sometimes, if you mess about or leave the body at any point (or enter internal locations which require the game to go to a loading screen), it will disappear leaving no other option but to return to an earlier save point and return to the body's location to complete the quest.
 * Ranger Morales is in pieces before you get even close to the body. There are no mines by it. This means that you cannot complete the quest. He may also be stuck inside the pavement, in which case you cannot shoot him.
 * Esteban can be seen blinking even though he is dead.
 * Sometimes, you won't receive the mission after talking to Pvt. Christina Morales, but you will be able to complete it regardless, just not get any reward for it.
 * Sometimes, You will hear NCR troopers say "We still haven't got Morales' body back from the fiends. Sure doesn't inspire confidence in the guys you're serving with." even though you have already taken his corpse back and spoke to private Morales and gotten your reward.
 * The body of Morales' friend Ranger Jackson may not spawn between two of the buildings north of Morales' body, by a rigged shotgun & tripwire.
