Santiago

 is a character in the Grand Canyon in 2253.

Background
Apparently owes Francine a sizable number of caps (somewhere in the order of 388 or so).

Interactions with the player character

 * You can have sex with him for 25 caps.
 * He can be recruited to fill the role of a suave prostitute for the Garret Twins' prostitution ring at the Atomic Wrangler Casino for the second part of quest Wang Dang Atomic Tango.

Appearances
He is located inside Freeside. He can be killed without losing karma.

Bugs
The option to recruit for the Garret Twins' prostitution ring (Atomic Wrangler Casino) him is available upon meeting him, if the quest Wang Dang Atomic Tango has been accepted. This will inadvertently accept and accomplish the initial quests of Debt Collector up to the fine-paying, and all options to pay the fine, except out of pocket are gone. This also will screw up your interactions with Francine and possibly prevent the player from completing the quest.
