Winton Holmes was a refinery worker. At some point, Winton lost his job and became financially unstable, which resulted in him taking a loan from Leopold Strauss.
Events of Red Dead Redemption 2
Arthur confronts him, demanding he repay the loan. Winton claims he has no money, but instead suggests they hunt a rare White Cougar, implying they sell the hide for money. Arthur has no option but to agree.
Arthur and Winton travel to the mouth of a cave, where Winton suggests they split up and search different areas of the cavern. As Arthur is searching, he hears a yell and begins looking for Winton.
Winton's corpse is found by Arthur, bloody and covered in scratches and bite wounds. Not far from his body is the Cougar. Arthur opens fire and successfully kills the cat. Its skin is later sold to pay off Holmes' debt.
