After you defeat Hoodoo, there will be a intermission sequence showing him dead standing up in a coffin. After the sequence, he will still be in west empire standing in the grave. You can take out your double-barrel shotgun and shoot him a few times in some areas. You can shoot off his head, arm, and both of his legs. leaving a corpse floating in an up-right coffin.
You can make more money on the bounty hunter side missions by capturing bounties alive. When you find a wanted poster that offers more money if you capture them alive and are having trouble doing so, use the following trick. Kill all gang members or bodyguards (if any). If the bounty is on a horse, kill the horse. Get close and melee attack. This will stun the fugitive and present an opportunity to grab them. Then, subdue the fugitive.
This awards you more money for each bounty. If you accidentally release him, you can try to melee him and grab him again. However, if you do this too many times or if he has been shot, you may kill him and get less money.
