Tom Joad kills Herb Turnbull

Tom Joad kills Herb Turnbull in a drunken fight at a dance, an act that sends him to McAlester State Penitentiary for four years and shapes his identity as a paroled killer when the novel opens. The killing is not a calculated crime but a reflexive, near-accidental blow struck with a shovel after Turnbull had already stabbed Tom, and it becomes the defining event of Tom's past—a past he refuses to regret and that the family treats with a mixture of shame, pride, and protective silence.

Circumstances of the Killing

The fight occurred at a dance when both men were drunk. Tom describes the sequence to Jim Casy under the willow tree: "I killed a guy in a fight. We was drunk at a dance. He got a knife in me, an' I killed him with a shovel that was layin' there. Knocked his head plumb to squash." The shovel was leaning against the schoolhouse, and Tom grabbed it only after Turnbull came at him a second time with the knife. Tom insists he had no prior grudge against Herb Turnbull, calling him "a nice fella" who had once courted his sister Rose of Sharon. The violence was situational and spontaneous, not premeditated.

Legal Consequences and Parole

Tom received a seven-year sentence for the killing, though he notes that the judge gave him a "light sentence 'cause it wasn't all your fault." He served four years at McAlester State Penitentiary before being paroled. The terms of his parole restrict him from leaving the state of Oklahoma, a condition that creates immediate tension when the Joad family decides to migrate to California. Tom tells the truck driver who gives him a lift that he was "sprung in four for keepin' my nose clean," and he carries his parole papers with him when he returns home. The family is acutely aware of this legal constraint: Pa worries about it, Al reports hearing that crossing the state line would send Tom back for three years, and Ma's anxiety about Tom's legal vulnerability shapes many of her decisions on the road.

Tom's Moral Stance and the Family's Response

Tom expresses no remorse for the killing. When Casy asks if he is ashamed, Tom replies, "No, I ain't. I got seven years, account of he had a knife in me. Got out in four—parole." He tells Muley Graves that if Herb Turnbull came at him with a knife again, he would "squash him down with a shovel" a second time. This unapologetic stance is rooted in Tom's sense that the killing was self-defense and that the legal system's punishment made no meaningful sense—a theme he explores with a fellow inmate who studied prison systems and concluded that the whole institution was irrational. The family's response is more complex: they do not condemn Tom, but they treat the killing as a dangerous fact that must be managed. Grampa boasts that he threatened the Turnbull family, and the community's talk of revenge is eventually talked down. Ma's deepest fear is not that Tom is bad but that the prison system has made him "mean-mad" like Pretty Boy Floyd—a fear Tom reassures her is unfounded.

Narrative Role and Significance

The killing of Herb Turnbull establishes Tom Joad as a man who has already crossed the line into lethal violence before the novel's main action begins. This backstory gives Tom a hardened edge and a practical knowledge of the criminal justice system that sets him apart from his family. It also creates the central legal jeopardy of the novel: Tom's parole violation when he crosses into California becomes the mechanism that forces him into hiding and ultimately into his final separation from the family. The killing is the first of two homicides Tom commits in the story—the second, the vigilante he clubs to death after Casy's murder, repeats the pattern of a spontaneous, morally justified blow struck in defense of another. Together, the two killings trace Tom's arc from a man who killed in a personal fight to one who kills in a collective struggle, a transformation that the novel presents as a form of moral growth rather than degeneration.
