A Final Plan for Esteban

 is a quest in Fallout: New Vegas.

Quick walkthrough
Retrieve the corpse of NCR Private Christina Morales her husband, located to the east of REPCONN Headquarters. His corpse is used by Fiends to lure in NCR troops, so take them out first, then grab the corpse and drag it to the troops, they're just down the way to the north of the place you found him.

There is no quest associated with this task; when accepted a note is added under the Misc section of the Pipboy's Data menu.

Journal entries
"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."
