Sometime before the year 1899, Brown was a bounty hunter himself and was able to get away with several previous murders, according to Sheriff Farley. However, he later murdered several innocent people and thus a $40 bounty was put on his head by the Big Valley Sheriff's office in Strawberry.
Events of Red Dead Redemption 2
In Strawberry, the player can collect a bounty poster for Brown. Before the protagonist sets off to find him, Sheriff Farley warns them that Brown is not only dangerous, but already has a number of other bounty hunters on his trail.
The protagonist eventually comes across the abandoned mine known as Beryl's Dream and looks around for signs of human activity. Suddenly, Brown confronts them and says that the only way out of the situation is to defeat him, initiating a duel. Brown is promptly disarmed, before being hogtied and taken back to Strawberry.
Joshua Brown is then delivered to Strawberry jail, much to Farley's amazement. After Brown is locked in the cell downstairs, the protagonist collects the $40 reward money from Farley.
At first, the in game messages will tell the player that Joshua Brown is wanted dead or alive, however he must not be killed in the duel, as he is actually wanted alive. Should the player kill him, the mission will not progress and you will have to reload the save profile.
In order to win, the player must shoot only once at a non-fatal part of his body such as the leg or arm, which stuns him and causes him to drop his weapon. Alternatively, the player can disarm him directly by shooting his gun. To do this, the player is required to fully charge the draw meter and immediately shoot his hand when he reaches for his gun.
Moreover, since the player will not lose Honor from this duel, due to the opponent being a bounty target, the easiest way to beat Brown is by cheating. To do so, the player should immediately activate Dead Eye and manually aim instead.
