Redmond's killing turns the visitors' demand for a sacrifice back upon the people making it. The dead man is identified as Jeff O’Bannon, Andrew's former attacker; the revelation makes the cabin's violence part of a history that predates the siege. Sabrina's later account places her, Andrew, and Eric in the killing, but she remembers it only in fragments and cannot say who delivered the fatal blow.

Identity and Circumstances

At first, the dead man is known to the family as Redmond. Andrew recognizes him only after Sabrina confirms that the visitors are using their real names. He then insists that Redmond is Jeff O’Bannon, the man who attacked him at a bar in Boston. O’Bannon's changed appearance—his shaved head, heavier build, and swollen-looking face—had kept Andrew from recognizing him immediately. The name brings the earlier assault into the cabin: Redmond is not merely one of the armed strangers, but the person who had already made Andrew a target.

Andrew's recognition is emphatic, though Eric is less certain that he remembers O’Bannon or can match the name to Redmond. Andrew's lingering questions about why O’Bannon chose him give the identification a painful personal charge. The killing therefore has two meanings at once: it is an act of violence within the siege, and the death of the man responsible for an earlier attack whose motives Andrew never fully understood.

Violence and Its Aftermath

The killing precedes the renewed demand that Andrew and Eric choose one of themselves to die. Leonard argues that the past cannot change the choice before them and that they were selected to pass a test. Andrew counters with the immediate facts of their captivity: he and Eric are tied to chairs, and the visitors have killed the man whose body lies on the deck. His appeal treats the killing as evidence against the visitors' claim to moral authority, rather than as a deed that can be set aside in service of their supposed mission.

The violence also leaves practical traces in the cabin. Adriane stacks three homemade weapons by the woodburning stove and spends more than an hour washing them with warm water and dish detergent, then drying them with hand towels. The next day, Leonard and Sabrina take up the same weaponized wooden staffs they had wielded before, holding them with the assurance of people who have already used them successfully. Adriane's cleaned weapon, by contrast, is propped against the stove and left unused. The implements move between violence, cleaning, and renewed threat; their orderly handling does not undo what has happened.

Sabrina's Recollection

Sabrina later tells Andrew and Eric that the three of them killed Redmond. She describes her state at the time as trance-like, while acknowledging that she has no prior experience by which to judge what a trance is. She believes that part of her was absent, as if lost in the vision of an endless destruction in a valley, while enough remained for her to perceive Redmond's masked face and feel the wooden handle vibrate in her hands as she struck him.

Her account is deliberately incomplete. Sabrina cannot recall how many times she swung, cannot reconstruct the struggle in detail, and cannot identify which of the three dealt the final blow. She says that even her memory of the fight at Andrew's SUV has already faded to only its broadest traces. The killing is thus both a confirmed event and a broken recollection: Sabrina accepts her participation but cannot offer a stable, complete sequence of actions. Her testimony establishes collective responsibility without assigning the decisive act to a single person.

Significance in the Siege

Redmond's death exposes a contradiction at the heart of the visitors' ultimatum. They demand that the family sacrifice one of its own, while the group itself has already killed a member; Leonard nevertheless insists that the past is irrelevant to the test and urges Andrew and Eric to comply. Andrew refuses that separation between doctrine and conduct, pointing to the bound men and the body on the deck as evidence of what the supposed test has already made ordinary.

The later account also complicates the killing without excusing it. Sabrina's sense of absence and the gaps in her memory distinguish the act from a clear, fully remembered decision, but her own statement still names the three participants. The identity revealed by Andrew gives the death an additional personal consequence, while the uncertainty over the final blow prevents the event from resolving into a simple act of revenge. In the siege's moral conflict, the killing is both a breach of the visitors' claimed authority and a further instance of the violence through which that authority is enforced.
