The Eric Thompson trial, which was extensively featured by Dateline, was the most scandalous and publicized criminal trial in Hawaii over the last decade. Eric Thompson, the "Bucket Hat Killer," was convicted of second-degree murder for shooting to death well-respected Waipahu, Hawaii, acupuncturist Jon Tokuhara in January 2022.
Dateline reporting leaves no question that Thompson's murder was premeditated, based on an unbalanced love triangle with Joyce and Tokuhara. The trial, the investigation, and subsequent sentencing were all watched closely by the public, and the case is a perfect example of how offending can be the result of betrayal.
Dateline dedicated an entire episode, "The Bucket Hat Killer," to the crime, investigation, and personal repercussions. The episode provides observers with an objective, detached account of what took place, tracing both motive on a personal level and forensic data leading to Thompson's arrest and conviction.
It also traces the personal repercussions on the victim's family and community, discovering how one act of violence has ripple effects far beyond the immediate location.
Here are 5 harrowing details about the Eric Thompson case, revisited by Dateline
1. Eric Thompson's background and childhood
Eric Thompson was a single-parent son who was from Hawaii and had grown up in poverty as a teenager. Clearly still ambitious and dedicated even after his hardships, he worked and gained a degree in Biology. Thompson entered into business and commenced a profitable bathtub remodelling business. Through his business, he was able to purchase his family a $2.15 million home and financially support his wife Joyce and daughter.
But Thompson's life was not an arrow straight. Though as successful as he was in his profession, his life was marred with serious problems, i.e., personal problems with his wife worsening on a daily basis. Dateline openly disclosed that his friends had labeled Thompson as brilliant, ambitious, and forceful but dominating when dealing with matters of his personal life.
These personal relationships were also crucial in figuring out the motive behind the murder of Jon Tokuhara and how interpersonal feelings and issues got out of control, resulting in tragedy.
2. The love triangle that ended in tragedy
Murder was perpetrated by Thompson because of his extramarital affair with his wife Joyce and Tokuhara. Joyce went to see Tokuhara initially for fertility treatments, which subsequently turned into an illegal affair. The affair only came to light in mid-2021 when it was publicly revealed with Thompson by Joyce, and strains and altercations within the house began.
Joyce and Thompson also entered into a post-nuptial in December 2021, relinquishing their house and daughter to Thompson in case of divorce. This was a legal procedure that confirmed the failed marriage and attempts at coming to terms with the fact of the affair. Dateline needed the love triangle, rage, and sense of betrayal by Thompson to be at the center of establishing the motive for murder.
It is appropriate to describe how intimate relations and public conflicts turn into vicious cycles of violence.
3. Murder and critical evidence
Jon Tokuhara was also killed on January 12, 2022, in his Waipahu acupuncture clinic. A white bucket hat-wearing male subject who showed up on surveillance cameras in front of the office at the time of the killing was seen. The discarded white bucket hat used as evidence was where DNA evidence strongly implicated Thompson. This served as a basis to determine that Thompson was present at the crime.
The programme, seen on Dateline, covered all aspects of the case, from computer and forensic evidence to testimony and facts. The police methodically re-lived the sequence of events, tracing Thompson's motive and planning. Forensic science as a solution to solving modern-day criminal cases is what the programme is profiling, how DNA profiling, CCTV footage, and thorough investigation intersect and result in convictions.
4. Arrest, bail, and judicial proceedings
Eric Thompson was initially released on a $1 million bond during the arrest, but was held following the mistrial for his first trial. His second trial took place early in 2025, when the prosecution enjoyed greater latitude to build its case. Dateline filmed the trial in detail, from the law, courtroom politics, and emotional testimony by Tokuhara's family.
Thompson was convicted in February 2025 of second-degree murder and felon in possession of a firearm. He was sentenced to life with parole after 15 years in June 2025. The Dateline episode illustrates how the trial brought into relief both the prosecution's deliberation theory and efforts at constructing alternative explanations by the defense, and the openness and detail of the legal process were therefore made transparent.
5. Victim impact and community reaction
The killing impacted Tokuhara's family and his community as a whole tragically. His mother found him dead at the clinic, witnessing unimaginable pain and trauma. While sentencing Tokuhara, his sister gave a victim impact statement about the long-term emotional and psychological impact of the offense. Dateline segments utilize such close-knit stories, analyzing how families deal with the aftermath of violent crimes.
The people of Waipahu were also heavily hit by the crime, and the residents who happened to be in the community when the crime was committed were left shocked and amazed by what happened. Dateline quoted an overview of the reactions from the community, which was the ripple effect of the violence between the networks and communities of the people.
The program highlights that even with the conviction, which ensures legal closure, the psychological and emotional impact still exists years after the trial.
The Eric Thompson case remains one of Hawaii’s most shocking and instructive criminal stories, extensively documented on Dateline. The murder of Jon Tokuhara, stemming from a love triangle and personal betrayal, showcases the devastating consequences of unresolved conflicts. From the key evidence, including the white bucket hat and DNA links, to the trial, sentencing, and emotional aftermath, every aspect of the case demonstrates the meticulous nature of law enforcement, the legal system, and media coverage.
Dateline reporting guarantees that the audience is given a full, honest, and balanced grasp of what has occurred. Eric Thompson's incarceration at Halawa Correctional Facility seals the judicial process, yet the social and emotional reality of the case remains important.
