The Coyotes

 is a side quest in Fallout: New Vegas.

Quick walkthrough
It is given by Captain Parker at the Aerotech Office Park. He wants you to find the missing refugees and suggests you start in Westside.

Detailed walkthrough
1. Head to Westside (usually by way of its southern gate) and talk to Saint James as Dermot won't tell you a thing (Follow the compass).

2. Enter the Casa Madrid Apartments to locate the evidence. Dermot's room contains a ledger, and to complete the Saint James evidence, you can either break into his room via lockpicking, or talk to Sweetie who is upstairs to find out about Saint James if you pay her money (If you have the Lady Killer perk you can get the key for free). She also has a spare key. Barter checks reduce the cost. In Saint James room, to complete the objective, pick up the teddy bear from his bed and in Dermot's room pick up Dermot's ledger from his table.

3. (Optional) If you confront either Saint James or Dermot by talking to them, they will attack you. Saint James uses a power fist and Dermot has a 9mm SMG.

4. (Optional) If you choose to kill Dermot and Saint James, you may also choose to talk to Pretty Sarah and explain what the pair were exactly up to. She will reward you with 4 Med-X.

5. Head back to Captain Parker for your reward: 250 XP and 150 caps.

6. If you choose not to confront Saint James or Dermot, and go straight to the Captain, you can still complete the mission.

Bugs

 * After accepting this quest, the quest marker on the compass points towards a location that is impossible to reach, Also the person you are meant to talk to in Westside cannot be found, the quest is impossible to complete without this NPC.
 * In both Stage 4 and 5 in some games its impossible to "turn in" the quest to Parker. Sometimes finishing the conversation and starting a new one will trigger the correct response. If you find it impossible to turn in the quest on the PC selecting Captain Parker with the console open and typing  or  will enable the correct conversation choices.  On a console, if the conversation option doesn't turn up to finish the quest, simply change outfits to 'gang' related outfit, and then talk to him.  Usually changing people's opinions about you restarts conversation loops.  On the PC, the quest-concluding conversation option appears after entering and exiting conversation with Parker twice and then initiating conversation for a third time.
 * Saint James may not have a key to his room in his inventory and he may become stuck inside his room. The quest may not be able to be finished if this happens and you do not have 50 lockpick skill or if Pretty Sarah doesn't offer you a key.
