What is the first name of the person who commits suicide? Answer the above question based on the context below: A gunfighter and gambler, John Oakhurst ends up caring for a baby girl whose mother dies in childbirth. He decides to call her "Luck" and looks to new schoolmarm Helen Colby and the Rev. Sam Woods to set a good example for the girl. Luck grows up and Poker Flat grows into a boom town. One day while John and the reverend are quarreling about the bad element John and his partner The Duchess permit in their gambling house, Luck ends up playing cards with Sonoma, a vicious outlaw. A furious John explodes at Helen, feeling she was supposed to be keeping an eye on Luck at the time. Helen decides to leave town, but Luck convinces her that John loves her. Determined to change into a better man, John refuses to be goaded into a showdown by Sonoma, at least until The Duchess taunts him, whereupon he shoots dead Sonoma and another man. A vigilante group orders John and The Duchess out of town and Helen goes along. Their horses are stolen and, in the mountains in winter, The Duchess freezes to death. Helen nearly dies, but just as Luck rides up to rescue her, they find that John, feeling guilt for what he's done, has taken his own life.
