Introduction: The Central Question of Season Three
The central mystery propelling the third season of 13 Reasons Why is a stark and provocative question: Who killed Bryce Walker? The direct answer is that Alex Standall delivered the fatal push that sent a grievously injured Bryce Walker into the river to drown.1
However, to reduce the event to this single action is to miss the season’s core argument.
Bryce’s death was not a singular act but the catastrophic culmination of a chain reaction of violence, trauma, and a collective moral failure among the students of Liberty High.
The season marks a significant narrative pivot for the series, shifting its focus from the aftermath of suicide to a complex whodunit that deliberately blurs the lines between victim and perpetrator, testing the moral boundaries of its protagonists.3
The final, fatal moments on the pier involved a sequence of actors, each contributing to the outcome.
Zach Dempsey’s initial assault left Bryce incapacitated; Jessica Davis stood as an eyewitness and accomplice; and ultimately, the core group of friends became co-conspirators in a criminal cover-up designed to protect one of their own.5
This report will provide a definitive analysis of Bryce Walker’s death, beginning with a meticulous chronological breakdown of the murder itself.
It will then explore the intricate web of suspects and motives that defined the season’s structure, deconstruct the architecture of the ensuing cover-up, and examine the profound thematic implications of this event, which irrevocably altered the moral landscape of the series.
Section 1: The Final Moments on the Pier – A Chronological Breakdown
The death of Bryce Walker was not a singular, impulsive event but a multi-stage process that unfolded on the night of the Liberty High Homecoming game.
Each act of violence directly precipitated the next, creating a causal chain that began with past grievances and ended in the dark waters of the river.
The Catalyst: The Homecoming Game and the Attack on Zach
The narrative establishes the Homecoming game between Liberty High and Bryce’s new school, Hillcrest, as the flashpoint for the night’s events.7
Before the game, Bryce approached Jessica Davis, one of his rape victims, and asked her to meet him at the pier afterward.
He intended to give her a cassette tape containing a confession and apology for his crimes.5
This action, ostensibly a step toward redemption, ironically set the stage for his demise by ensuring key figures would converge at the location of his death.
The situation escalated during a large brawl that erupted on the field following a protest organized by Jessica against sexual violence.
Bryce, having learned that his former friend Zach Dempsey had supported his ex-girlfriend Chlöe Rice through her abortion of Bryce’s child, used the chaos of the fight as cover for a targeted attack.
He deliberately dove into Zach’s knee, shattering it and effectively ending his promising football career.5
Act I: Zach Dempsey’s Retaliation
Enraged and devastated by his career-ending injury, Zach followed Bryce from the team drop-off point to the docks where Bryce was waiting for Jessica.5
There, Zach confronted his former friend and unleashed a brutal beating, breaking Bryce’s arm and one of his legs.6
Zach left Bryce helpless and exposed to the cold but critically, he left him alive.
For a significant portion of the subsequent investigation, Zach himself believed he might have been the killer, making him both a convincing red herring and a partial perpetrator whose actions were an essential precondition for the final outcome.9
Act II: The Arrival of Jessica and Alex
Minutes after Zach departed, Jessica arrived at the pier as planned.
She brought Alex Standall with her for protection, a decision that would prove fateful.6
Jessica’s boyfriend, Justin Foley, was notably absent; he had relapsed and was secretly at the waterfront buying drugs, a detail that underscores the persistent trauma and dysfunction plaguing the group.5
They found Bryce broken and bloodied on the pier.
Despite his condition, Bryce managed to give Jessica the confession tape he had made for her—a final, desperate gesture of apology.5
Act III: The Fatal Push
As Jessica and Alex prepared to leave, Bryce, unable to move, asked for help.
In a moment of pity, Alex began to help him to his feet.1
This moment of vulnerability became the turning point.
Any illusion of Bryce’s redemption was shattered when his unrepentant nature erupted.
He began shouting threats, vowing to “f— up [Zach’s] other knee and wreck his life,” before turning on Jessica and accusing her of setting him up.5
In that instant, Alex was overcome by the accumulated rage and trauma that Bryce had inflicted upon their entire circle of friends.
Realizing that Bryce was incapable of change and would only continue to harm the people he loved, Alex uttered, “You’ve hurt everyone I ever loved,” and shoved him off the pier.1
With his arm and leg broken, Bryce was unable to swim.
Alex and Jessica watched as he struggled briefly before sinking into the water and drowning.2
The cycle of violence that Bryce had perpetuated for years had finally, violently, turned back on him.
Each escalating act of aggression—from his past rapes to his maiming of Zach, to Zach’s beating, to his final verbal threats—created an unbroken chain of causality that culminated in his death.
Section 2: The Web of Suspicion – A Comprehensive Suspect Analysis
The third season’s whodunit structure, narrated primarily through new student Ani Achola’s police interrogation, systematically builds plausible motives for nearly every major character.
This narrative strategy turns the audience into detectives, forcing them to sift through lies and red herrings.
This structure is not merely a plot device; it serves a deeper thematic purpose by deliberately inverting the established victim dynamics of the series.
The protagonists, long positioned as the victims of trauma, are now presented as credible murder suspects, forcing a re-evaluation of their moral standing.
The Narrator and Prime Suspect: Clay Jensen
Clay Jensen, the series’ moral center, was positioned as the primary suspect.
His long-standing hatred for Bryce, rooted in his role in Hannah Baker’s suicide, was compounded by a new, intensely personal conflict over his and Bryce’s mutual affection for Ani.8
This led to a public confrontation where Clay threatened Bryce, later sending a text message that read, “I want you dead,” shortly before Bryce’s disappearance.12
As the police’s main person of interest, Clay serves as the classic “wrong man” protagonist, compelling him and Ani to uncover the truth to exonerate him.3
The Accomplice: Jessica Davis
As one of Bryce’s rape victims, Jessica possessed one of the strongest and most righteous motives for revenge.8
Her activism and leadership of the “Hands Off” protest group demonstrated her resolve to fight back against the toxic culture Bryce embodied.15
Her presence at the murder and her possession of the blood-splattered confession tape made her a key figure in the crime.5
Her role transforms her from a victim seeking justice into a direct accomplice to a killing, complicating her journey of recovery.
The First Attacker: Zach Dempsey
Zach’s motive was twofold: raw vengeance for the career-ending injury Bryce inflicted upon him and fury over Bryce’s treatment of Chlöe.5
He confessed to beating Bryce severely and leaving him for dead, making him a crucial red herring.5
The discovery of his involvement is a major mid-season twist, but the fact that he did not deliver the fatal blow underscores the season’s complex exploration of culpability.
The Framed Man: Montgomery de la Cruz
Montgomery “Monty” de la Cruz was given a powerful motive when Bryce threatened to expose him to the police for the brutal sexual assault of Tyler Down.8
As a known violent offender with no alibi he was willing to provide—as it would have revealed his closeted sexuality—he became the perfect scapegoat.8
His tragic character arc, that of an abused and deeply conflicted young man, is ultimately co-opted by the protagonists, making him a victim of their cover-up.18
The Traumatized Victim: Tyler Down
Tyler initially believed Bryce was ultimately responsible for ordering Monty’s horrific assault against him.8
With a known history of planning mass violence and access to weapons, he was a potent suspect.13
The investigation was further complicated when it was revealed that the river where Bryce’s body was found was the same location where the group had disposed of Tyler’s arsenal of guns after stopping his planned school shooting.20
Tyler’s journey of recovery is constantly juxtaposed with the suspicion that he could relapse into violence, making him a powerful but ultimately misleading suspect.4
The Unreliable Narrator: Ani Achola
As the new girl at Liberty High, Ani’s role was shrouded in mystery.
She had engaged in a secret sexual and emotional relationship with Bryce, which turned sour when he became violent with her.8
Her intimate knowledge of everyone’s secrets, her position as the narrator confessing to the police, and an early scene of her washing blood from her clothes made her deeply suspicious.13
Many viewers speculated she could be the killer, manipulating events to frame someone else.21
Ultimately, her primary motive becomes protecting Clay, and she serves as the architect of the season’s unreliable narrative, forcing the audience to constantly question the nature of truth.5
| Suspect | Primary Motive(s) | Key Actions/Alibi on Homecoming Night | Narrative Role |
| Clay Jensen | Revenge for Hannah Baker; jealousy/protection over Ani Achola. | Publicly threatened Bryce; sent incriminating texts. Alibi provided by Ani (falsely). | Primary Suspect / Red Herring |
| Alex Standall | Accumulated rage over the harm Bryce caused to his friends, particularly Jessica. | Was present at the murder; pushed Bryce into the river. | The Killer |
| Jessica Davis | Revenge for her rape; desire to protect other victims. | Was present at the murder; became an accomplice by silence. | Accomplice / Moral Barometer |
| Zach Dempsey | Revenge for a career-ending injury; anger over Bryce’s treatment of Chlöe. | Brutally beat Bryce at the pier, breaking his arm and leg, but left him alive. | The First Attacker / Red Herring |
| Montgomery de la Cruz | Fear of being exposed by Bryce for sexually assaulting Tyler Down. | Had an alibi (was with Winston Williams) but refused to use it to protect his secret. | The Scapegoat |
| Tyler Down | Believed Bryce was responsible for his sexual assault; history of planned violence. | Was not present at the murder; his disposed guns created a misleading link. | Red Herring / Symbol of Trauma |
| Ani Achola | Complicated relationship with Bryce; primary goal was protecting Clay. | Narrated a false version of events to the police to frame Monty. | Unreliable Narrator / Architect of the Cover-up |
Section 3: The Architecture of a Lie – Engineering the Cover-Up
The conspiracy to conceal the truth of Bryce’s murder is as thematically significant as the crime itself, marking a profound moral decay within the protagonist group.
Their actions evolve from the passive complicity and silence that defined their guilt in the first season to an active, criminal conspiracy in the third.
The Mastermind: Ani Achola’s False Narrative
Upon learning of Alex’s guilt and, separately, of Monty’s off-screen death in jail, Ani Achola devises a plan to frame Monty for the murder.16
She constructs an elaborate false narrative for Deputy Standall, weaving together truth and fiction.
She leverages the real-life fact that Bryce had threatened to expose Monty for assaulting Tyler, presenting this as a plausible motive for murder.5
To complete the deception, she provides a false alibi for the police’s primary suspect, Clay, claiming he was with her on the night of the murder.
This act not only saves Clay but also implicates him and the rest of the group, who agree to the plan, in the conspiracy.16
The Corrupted System: Deputy Standall’s Complicity
The cover-up’s success hinges on the complicity of a figure of authority: Alex’s own father.
Deputy Standall quickly deduces that his son is the true killer.23
Faced with an impossible choice between his duty as an officer of the law and his love for his son, he chooses to protect his family.
He actively participates in the obstruction of justice, accepting Ani’s fabricated story and personally destroying the most crucial piece of evidence: the blood-stained clothes Alex was wearing on the night of the murder.16
This elevates the group’s crime from a conspiracy among teenagers to a systemic failure of the very institution meant to provide justice.
The Convenient Scapegoat: The Death of Monty
Monty’s fate provides the lynchpin for the entire cover-up.
After being arrested for the sexual assault of Tyler, he is killed in his jail cell by another inmate, an act of supposed vigilante justice.16
His death occurs off-screen and is reported secondhand, a narrative choice that fueled speculation he might not be truly dead and added a layer of instability to the conspiracy’s foundation.19
The group seizes upon this tragedy, callously pinning the murder on a man who can no longer defend himself or provide his real alibi.18
They transform him from a complex, tormented aggressor into a simple, convenient solution to their own criminal problem.
Section 4: Narrative and Thematic Implications
The murder of Bryce Walker and the subsequent cover-up serve as the series’ ultimate moral turning point, raising complex questions about justice, redemption, and guilt that resonate long after the season’s conclusion.
The Aborted Redemption Arc
Season 3 invests significant narrative energy in attempting to humanize Bryce Walker.
He is shown grappling with the consequences of his actions, attending therapy, and expressing remorse, portrayed at times as a “hurting child living with his mistakes”.4
This complex redemption arc is violently negated in his final moments.
His threats to further brutalize Zach and his accusation against Jessica reveal that his predatory nature remains intact beneath a thin veneer of remorse.5
This deliberate contradiction leaves the audience in a state of moral ambiguity: Does an attempt to atone matter if, under pressure, a person reverts to their worst self? The show refuses to provide a simple answer, questioning whether some individuals are truly beyond redemption.
Vigilante Justice and Systemic Failure
Alex’s decision to kill Bryce can be interpreted as an act of vigilante justice, a final, desperate measure to stop a predator whom the legal system had failed to hold accountable.
Bryce’s trivial sentence of three months’ probation in Season 2 for his serial rapes is the foundational injustice that leads directly to the events at the pier.4
The cover-up, aided and abetted by a police officer, reinforces the theme that formal institutions of justice have failed these teens.
It suggests a world where justice is not dispensed by the system, but must be seized and manipulated by individuals, with devastating consequences.
The Ticking Time Bombs for Season 4
The season finale masterfully leaves two major plot threads unresolved, ensuring the conspiracy is built on unstable ground.
- Winston’s Alibi: The most significant threat is Winston Williams, the Hillcrest student who knows Monty is innocent because they were together on the night of the murder.16 In the final scene, he confronts Ani, aware of the lie and vowing that Monty did not deserve to have his name tarnished in death.5 This confrontation establishes the central conflict for the final season, as Winston holds the power to unravel the entire deception.
- The Fisherman’s Discovery: In the closing moments of the season, a fisherman pulls a duffel bag from the river containing the arsenal of assault rifles that the group had dumped to protect Tyler after his aborted school shooting attempt.9 This discovery physically links the cover-up of Tyler’s crime to the location of Bryce’s murder, creating a ticking time bomb that threatens to expose all of the group’s secrets at once.
The framing of Monty is more than a mere plot device; it is a symbolic transference of the group’s collective guilt.
For three seasons, the protagonists have carried the immense weight of their trauma and their complicity in the events surrounding them.
By killing Bryce, Alex acts as an avatar for the group’s shared rage.
By framing Monty, the group finds a psychological mechanism to purge themselves of this new, more tangible guilt.
They project the “monster” label onto a convenient, deceased vessel, allowing them to temporarily absolve themselves and maintain their fragile self-perception as “good people” forced to do a bad thing.
This dark ritual of purification sets the stage for a final season where this transferred guilt will inevitably return to haunt them.
Conclusion: The Lingering Echoes of a Drowning
In conclusion, the answer to the question of who killed Bryce Walker is profoundly multifaceted.
While Alex Standall was the direct agent of death, the event was the inevitable product of a relentless cycle of violence, a justice system that failed its victims, and a collective decision by the protagonists to embrace criminality for the sake of self-preservation.
This act fundamentally reconfigured the moral architecture of 13 Reasons Why.
It completed the transformation of its central characters from victims into perpetrators, from silent accomplices into active conspirators.
The moral clarity that defined the series’ initial season is irrevocably lost, replaced by a deep and unsettling ambiguity that challenges the very notion of heroes and villains.
The death of Bryce Walker was not the end of a story, but the beginning of a new, darker chapter—a story about how the desperate quest for justice can lead to damnation, and how the secrets kept to protect friends can become the very chains that bind them together in a shared, inescapable guilt.
