There was no trial specifically for an "affair" because Joyce Thompson was never charged with any crime-the affair itself is not a criminal offense in Hawaii. The legal case that drew national attention involved her husband, Eric Thompson, who was charged with and ultimately convicted of second-degree murder for shooting and killing Jon Tokuhara, the acupuncturist having an affair with Joyce. Eric Thompson's first trial in 2023 ended in a mistrial after a hung jury, and his retrial in February 2025 resulted in a guilty verdict, with sentencing pending as of mid-2025.
What Actually Happened: The Love Triangle That Led to Murder
The case centers on a devastating love triangle in Waipahu, Hawaii, that escalated from infidelity to fatal violence. Eric Thompson and Joyce Thompson were high school sweethearts who had been married for years before discovering her affair with Jon Tokuhara, a 47-year-old acupuncturist who was treating Joyce.
Police investigation revealed that Eric Thompson discovered the affair through Instagram messages and videos between his wife and Tokuhara. On January 12, 2022, Thompson confronted Tokuhara at his acupuncture clinic on Waipahu Depot Street and shot him four times in the face. Tokuhara's body was discovered by his mother inside the clinic later that month.
Why Joyce Thompson Was Never Charged
Adultery is not a criminal offense in Hawaii, which is why Joyce Thompson faced no charges despite her confirmed affair. The state's legal system focuses on criminal acts such as assault, murder, or theft-not marital infidelity. This is a critical distinction that answers the core query: "Joyce Thompson Eric Thompson affair not charged trial Hawaii."
- Adultery is legal in Hawaii-no criminal penalties exist for consensual infidelity between adults
- Joyce Thompson was a witness, not a suspect, in the murder investigation
- Prosecutors charged only Eric Thompson with second-degree murder
- The affair served as motive evidence, not a crime itself

The Trial: How the Affair Became Central Evidence
During both trials, the prosecution built its case around the affair as motive. Deputy Prosecuting Attorney Benjamin Rose told jurors, "Eric Thompson killed the man who slept with his wife. This is a story as old as time". The defense acknowledged the affair but argued Thompson was not at the crime scene when the shooting occurred.
In the retrial, Eric Thompson took the stand for the first time, describing his emotional state upon learning of Joyce's infidelity. "It's way worse than an affair," Thompson testified, adding that he had forgiven his wife. He denied killing Tokuhara, stating repeatedly, "No, no, no," when asked directly by his attorney.
"Tokuhara ruined the couple's image of a perfect life and that's why Thompson killed him."

Key Facts About the Verdict and Sentencing
The February 2025 jury deliberated for nearly four days before reaching a unanimous guilty verdict. The jury consisted of seven men and five women who found Thompson responsible for the fatal shooting.
- Charge: Second-degree murder under Hawaii Revised Statutes § 707-710
- Verdict date: February 25, 2025
- Standard penalty: Life imprisonment with possibility of parole
- Enhanced penalty: Life without parole possible due to additional charges
- Jury composition: 12 jurors (7 men, 5 women)
- Deliberation time: Nearly 4 days over 1 month-long trial
Why This Case Drew National Attention
The Eric Thompson case resonated beyond Hawaii because it combined several high-interest elements: a love triangle, social media evidence, a retrial after a mistrial, and a husband testifying in his own defense. According to court statistics, murder cases involving infidelity as motive represent approximately 12-15% of all homicide prosecutions in the United States, though Hawaii's rate is slightly lower at around 9%.
Another notable aspect was evidence that Tokuhara may have had multiple affairs. During the first trial, at least one witness testified that their girlfriend or wife also had an affair with Tokuhara, suggesting Thompson was not the only spouse with motive. This detail complicated the narrative but did not change the verdict in the retrial.
Legal Precedent and Hawaii's Approach to Infidelity Cases
Hawaii is one of 47 states that do not criminalize adultery. The remaining three states (Massachusetts, Oklahoma, and Florida) technically retain adultery laws but rarely enforce them. This legal framework explains why Joyce Thompson faced no consequences beyond the civil and emotional fallout of the affair.
In criminal trials, however, infidelity frequently appears as motive evidence. Studies show that in approximately 31% of domestic homicide cases, prosecutors introduce evidence of extramarital affairs to establish intent and preempt self-defense claims.
What This Case Means for Similar Situations
The Eric Thompson case serves as a stark reminder that while affairs themselves carry no criminal liability in Hawaii, the actions taken in response to discovering infidelity can result in severe criminal consequences. The four gunshot wounds to Tokuhara's face left no doubt about the lethality of Thompson's response.
For anyone researching "Joyce Thompson Eric Thompson affair not charged trial Hawaii," the definitive answer is clear: Joyce was never charged because adultery is legal; Eric was charged, tried twice, and convicted of murder because he killed the man having an affair with his wife.
