Instructions
Play through and complete the first mission that you receive from Marshal Leigh Johnson, "Political Realities in Armadillo" to get the bounty hunter missions.
Look at the map for Wanted Poster icons, which look like skulls. There are eight wanted posters in Neuvo Paraiso, eight wanted posters in New Austin and four wanted posters in West Elizabeth. Head to one of the wanted posters to read them.
Find the wanted person on the map by looking for a skull in a red dot. When you get close to him, try to isolate him on the mini-map so that you can shoot and kill off his gang at a distance without having to take them on all at once. The wanted person's gang will show up as plain red dots on the map. Kill as many of the gang as you can.
Run or ride over to the fugitive. If he is on foot, shoot his legs to make him fall and slow him down, disarm him and use the lasso to catch and hog-tie him. Put him on the back of your horse. If your horse has run off on you, press "up" on the D-pad of your controller to whistle it to return to you. Ride back to town to turn in the wanted man to local law enforcement. You will be chased by the remnants of his gang, so be ready to fight them off while you make your way back to town.
