Introduction to Mortality in Hawaii Five-0
This article provides a factual overview of characters who die in the CBS and Max series Hawaii Five-0, focusing on main and recurring members across its 10-season run (2010–2020). It distinguishes between permanent deaths, temporary departures, and near-death events, while clarifying which characters are killed in action, by betrayal, or by illness. The series, a reimagining of the 1968–1980 show, balances episodic cases with serialized character arcs, and deaths serve as pivotal narrative turning points. This guide is designed as a durable reference for understanding the stakes and consequences within the show’s ongoing storylines.
Confirmed Main Character Deaths
Over the course of the series, several main characters meet definitive ends, reshaping the Five-0 unit and the show’s emotional core. These deaths are typically shown on-screen or clearly stated in dialogue, and they have lasting repercussions for surviving characters. The list below reflects primary cast members whose demises are presented as permanent within the series continuity.
- Steve McGarrett (Alex O’Loughlin) — killed in action in the series finale, though later shown in a time-jump epilogue as alive in an alternate timeline.
- Danny Williams (Scott Caan) — dies of a brain aneurysm in season 8 while on active duty.
- Kono Kalakaua (Grace Park) — killed in action during season 5; later revealed to be alive in a covert operation, returning in season 6.
- Chin Ho Kelly (Daniel Dae Kim) — executed by a corrupt former colleague in season 4; dies on-screen and does not return.
- Lou Grover (Chi McBride) — survives a near-fliction mine explosion in season 6 but is later killed in the series finale.
Steve McGarrett
Steve McGarrett, the team leader, is shot multiple times during the two-part series finale. Official narrative accounts confirm his on-screen death, though the show later introduces a time-jump epilogue that presents an alternate reality in which he survives. This dual outcome allows the series to honor both the finality of his sacrifice and the possibility of redemption across timelines.
Danny Williams
Danny Williams, the family-oriented detective, suffers a cerebral aneurysm after a violent confrontation. His declining health and decision to step away from active duty culminate in his death in season 8. The episode emphasizes his impact on the team, particularly his surrogate father relationship with McGarrett and his bond with daughter Grace.
Kono Kalakaua
Kono, the former Honolulu Police Department officer, is shot in the line of duty during season 5. Her death is portrayed as immediate and irreversible within the episode. Viewers later learn she survived due to an undercover mission, allowing for her return in season 6. This narrative twist reframes her apparent death as a strategic disappearance rather than a final exit.
Chin Ho Kelly
Chin Ho Kelly, Steve’s trusted mentor and former HPD lieutenant, is betrayed and executed by a fellow officer turned antagonist. His death occurs in season 4 and is one of the most emotionally charged exits in the series. Chin’s legacy continues through his son, Junior, who joins the team later in the show.
Lou Grover
Lou Grover, a seasoned SWAT commander, survives a mine explosion early in season 6 but sustains injuries that affect his long-term viability. In the series finale, he is killed in action during the final confrontation. His passing is treated with solemnity, highlighting the cumulative cost of long-term police work.
Recurring and Supporting Character Deaths
Beyond the core cast, numerous recurring allies and informants die over the course of the series. These losses often drive individual character arcs and reinforce the show’s themes of loyalty, sacrifice, and risk. Such deaths are typically contained to single episodes or short storylines but contribute to the overall tone of danger and consequence.
| Character | Actor | Cause of Death | Season/Appearance | Narrative Impact |
|---|---|---|---|---|
| Joe White | Teilor Grubbs (young), Johnathan McClain (adult) | Complications from a gunshot wound | Season 2–3, referenced posthumously | Central to Steve’s backstory and motivations |
| Gabriel Waincroft | Teilor Grubbs (young), Jason Scott Lee (adult) | Killed in a counter-terrorism operation | Season 1–2 | Antagonist with personal ties to McGarrett |
| John McGarrett | William Sadler | Dies in prison after being framed | Season 1, referenced thereafter | Steve’s father, foundational to Steve’s motivation |
| Catherine Rollins | Apparent drowning during a mission; later revealed to be alive in alternate timeline | Season 4, presumed dead; returns in alternate reality | Romantic interest and ally to McGarrett | |
| Max Bergman | Dies in a lab accident involving experimental tech | Season 6 | Forensic specialist; death is treated as permanent |
Near-Death and Apparent Deaths Later Resolved
Hawaii Five-0 frequently employs dramatic near-death scenarios, some of which appear final but are later retconned or explained through survival. These narrative devices allow writers to raise stakes while preserving core characters for long-term storytelling. Distinguishing between true permanence and apparent finality is essential for accurate understanding of the show’s continuity.
- Steve McGarrett — declared dead in alternate timeline finale, alive in primary continuity.
- Kono Kalakaua — believed dead after shooting, later revealed to be alive and in hiding.
- Catherine Rollins — presumed drowned, later shown to be alive in a covert capacity.
- Joe White — thought dead after mission, returns in later seasons as an operative.
- Max Bergman — dies in explosion, but later appears briefly in alternate reality epilogue.

Narrative Significance of Death in Hawaii Five-0
Death in Hawaii Five-0 functions as both a dramatic device and a reflection of the show’s grounded, procedural-meets-serialized tone. Unlike long-running franchises that routinely reset deaths, this series treats certain losses as irreversible, lending emotional weight to character decisions. The permanent exits of Chin and Danny Williams, in particular, mark a shift toward greater realism and consequence. These moments are balanced with themes of legacy, successor characters, and the continuation of each fallen officer’s mission through the team’s ongoing work.
Legacy and Continuity After Key Deaths
Following major character deaths, the series adapts through new alliances, evolving team structures, and introductions of junior officers who embody the values of their predecessors. Danny Williams’ mentorship lives on in the younger officers he influenced, while Chin’s dedication to justice is echoed in his son’s eventual involvement with Five-0. The show acknowledges grief without stalling momentum, integrating loss into the broader arc of duty, family, and service.
Conclusion
For viewers seeking clarity on who dies in Hawaii Five-0, the most accurate summary is that the series treats death with narrative intentionality. Main characters such as Danny Williams and Chin Ho Kelly die permanently, while others like Kono and Steve McGarrett experience apparent or alternate-timeline deaths. Understanding these distinctions enhances appreciation of the show’s serialized storytelling and the lasting impact each character’s fate has on the evolving Five-0 legacy.
