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 a 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.
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.
Private Morales has asked me to find and retrieve the corpse of her dead husband. His body is apparently being used as a lure to draw in NCR troops and slaughter them. Better keep a look out for traps and snipers...
The body is just east of REPCONN HQ and I should carry it to the troopers camped out on the north side of the railroad tracks.
I managed to get Ranger Morales' corpse away from the Fiends. I should return to Pvt. Morales and let her know her husband's body is safe.
One of the troopers at the barricade will mention that they lost a man named Ranger Jackson, but there is no reward for returning Jackson's body. Jackson's body is near the rigged shotgun trap between two nearby buildings (sometimes Jackson's body may not spawn).
If one approaches the barricade with any significant amount of damage while carrying Morales's body, the stunned NCR troopers will comment on how they sacrificed so much for a stranger.
Inversely, managing to retrieve the body, starting at full health without taking any damage at all, will elicit a similar level of astonishment at how they managed to pull off what they considered to be a near-impossible feat.
Troopers at Camp McCarran can be seen complaining about the NCR not retrieving the body and how this is affecting Morales.
Mr. New Vegas makes a report about this heroic deed once the corpse has been brought back, and Christina Morales has been spoken to.
