Sgt. Daniel Contreras

Sgt.  is a NCR supply merchant in Camp McCarran.

Background
Sgt. Contreras can be found in the Camp McCarran Supply Shack, the Supply Shack is accessible from a far end of Concourse area via a terminal tunnel. deals in shadier businesses, where it is implied he is making chems on the side for money among other things. Contreras will give you unmarked quests that are fairly easy to complete. Depending on your choices in the unmarked quest concerning inconsistencies in the the base's weapon ledgers, he may give you the unique rifle This Machine. After you have obtained This Machine by reporting him to (Lt.) Carrie Boyd, Contreras will no longer be present to sell supplies. However, he can be found for a time in a locked cell in the upstairs of the main building.

Appearances
appears in Fallout: New Vegas.

Bugs

 * Contreras stores the caps given to him in transactions in his personal inventory. Pickpocketing them does not seem possible even with a Stealthboy & 7 Luck, but I was able to sneak attack him after failing the pickpocket (but not being detected) and not lose Karma or anger NCR. Perhaps this was because I had already hacked his computer and found the evidence related to Dealing with Contreras? Regardless, I emptied his inventory of everything I care about, put one in his head, and then went to report his malfeasance to Boyd. I still received the quest credit and reward, and NCR dumped his corpse unceremoniously in the jail cell. (sneak attacking any member of any faction and successfully killing them in one hit will not grant you any loss of reputation.)


 * If you talk to Contreras during the NCR quest I Put a Spell on You, Contreras will not have the option that activate the unmarked quest to retrieve This Machine. (Confirmed)


 * Unmarked quest stops at the NCR ranger, Keller, with no secret stash access or This Machine, doesn't matter if you kill the ranger or work out a deal. (Confirmed by others, tested with old save and bug happening 4 out of 6 times. Don't know cause.)


 * Stops at Blake quest, Blake's dialogue is missing. (Confirmed)


 * If you want This Machine and are experiencing this bug you can still report Contreras to Carrie Boyd after the NCR ranger agrees to the deal. To do this just hacking his console on the 2nd floor of the supply shack and downloading the records. Then see Carrie Boyd, you will be given the This Machine as a reward and Contreras will disappear. (But beware: Contreras is the only supplier of Ultrajet in the game. Otherwise losing him is not a huge issue as he is so out of the way once you complete the Camp Quests.)


 * When asked to deliver the note to Isaac, Issac will not spawn outside of Gun Runners. If this happens, going in and out of his house will fix it.


 * When retrieving the medical supplies from Blake at the Crimson Caravan Company, be careful to acquire the medical supplies through dialogue with Blake rather than buying it from him through trading. If you should happen to buy the medical supplies in his trade inventory as well as acquire one through dialogue, you will not be able to give Contreras the medical supplies.  To correct this, consume all but one of the medical supplies (the medical supplies are consumable like doctor's bags, but are found in the Misc. section rather than the Aid section of your inventory), wait for a while, and then return to Contreras who should then be ready to take the supplies.


 * When buying supplies from Contreras he will sell a version of the Recon Armor worth 610 caps and in a very poor condition. After buying the Recon Armor, it will be in perfect condition in your inventory. To obtain more perfect copies of the Recon Armor, exit the buying screen and re-enter it to buy a maximum of 3 copies, after which, upon buying more Recon Armor, the armor will unbug and you will be left with only 1 version of the Recon Armor in its normal state. This has also occurred with the reinforced combat armor, mk. 2; buying any armor from him may be similarly bugged.


 * When wearing combat armor and you buy the same type, the transaction will deduct the price from your caps, but will not add the armor to your inventory. Simply take off your armor and give to Boone and then purchase.


 * If you sell Contreras any fiend armor he will wear it. Also true with Legion armor and Brotherhood Power Armor.


 * After shopping and browsing though Contreras' inventory, the dialogue will be exited with the frame frozen. He will also say goodbye, regardless of the frozen line of text, "Take your pick". Circle Button will not exit the interaction at this point, but the X button will.


 * Contreras will still function as a vendor after being imprisoned, but his inventory does not seem to update. On 360, it appears his inventory is emptied but he wil still buy things.
