Tucheng Domestic-Violence Double HomicideFull court observation notes, August 21, 2026

The incident occurred on July 7, 2025. After a protection-order hearing, Mr. Hsieh followed his wife and her younger sister by car, rammed their scooter, then attacked them with a blade and an aluminum rod, killing both.

May 17, 2025:Mr. Hsieh had a conflict with his spouse and assaulted her. Ms. Chang called the police and applied to the court for a protection order.

July 6, 2025:Mr. Hsieh went to Ms. Chang's residence to collect belongings and smashed a large ceramic money box nearby. Police referred him for a suspected protection-order violation. Public reports state that the prosecutor released him without bail after further questioning.

July 7, 2025:The court held a hearing on an ordinary protection order. Mr. Hsieh's spouse said that day that she wanted the complainant's representative to accompany her. After the hearing, Mr. Hsieh followed his wife and her younger sister by car, culminating in this incident.

The victims' side argued that this was not merely an ordinary killing but the use of death to torment the living, with the character of a cruel killing. According to their submission, Mr. Hsieh had said in message records that he wanted to kill his father-in-law but ultimately did not attack him. They argued that this was not simply abandoning the idea, but leaving the father-in-law alive to suffer the loss of his two daughters.

The prosecution argued that although Mr. Hsieh explained the four stages as intimidation, a voice's instruction, a chance encounter, and inability to distinguish tools, his conduct viewed continuously still showed a complete process from intention and preparation through approaching the targets and actual use.

Mr. Hsieh said he bought the tools because “a voice told me to buy them.” According to the psychiatric opinion recounted in court, this was not an auditory hallucination in the psychiatric sense, but closer to a concrete expression of his own thoughts or inner voice.

Mr. Hsieh also said he could not distinguish the knife from the rod at the time. It was pointed out in court, however, that before rushing toward the victims he switched the weapon to his dominant hand. The prosecution argued that switching hands, identifying targets, and changing weapons showed that he had not completely lost understanding and control.

The list's admissibility, creation time, and specific contents remain subject to the court's evidentiary examination and findings.

The prosecution used medical amputation as an analogy: a physician's removal of a necrotic limb has medical justification; destroying another person who is treated as a toy to satisfy a desire for control is entirely different, even if both involve removing limbs.

The prosecution also argued that the possibility of more cruel cases elsewhere does not mean this case is not among the most serious. If the possibility of an even worse crime always excluded death, the standard could never be applied.

There was a recess of about ten minutes during the hearing. Afterward, the presiding judge checked whether the citizen judges had further questions.

Though brief, this procedural moment reflects the rhythm of citizen-judge trials. Citizen judges not only hear both sides but can, with judicial guidance, raise matters needing clarification and later participate in deliberation and judgment.

According to statements in court, the expert report assessed Mr. Hsieh's overall risk of reoffending as “moderate.” The prosecution argued that differing assessment conditions and technical limitations might have led to underestimating the actual risk.

Risk is not only probability

The prosecution compared rain and infectious disease: even a 10% chance of rain may at worst mean getting wet, while a disease with only 1% mortality may still make people fearful of going out. The point was that risk assessment must consider the severity of consequences as well as likelihood.

The prosecution argued that rehabilitation and reintegration are two-way issues: whether the defendant truly understands responsibility and stops blaming others, and whether society can safely receive him in the future. Real rehabilitation is not merely following rules in detention; it means facing responsibility and reducing danger to others.

The prosecution argued that Mr. Hsieh's own actions deprived the children of their mother and destroyed their best interests. Those interests should therefore not become a shield for the defendant to avoid death.

This reply was brief. These observation notes do not speculate further about his mental state or infer remorse from silence alone. Any assessment must be considered with the whole of his statements, expert opinions, and evidence.

The defense described Mr. Hsieh as a husband and father who was gradually excluded from his family, whose self-worth was easily shaken by others' attitudes and family relationships, accumulating resistance, resentment, and frustration. This was the defense's explanation of the background, not a transfer of responsibility to the victims.

May 17:Mr. Hsieh went to his father-in-law's home, later conflicted with and assaulted his spouse. The defense said he had originally wanted to stand up for his wife and wanted her to return and to see his children.

July 2:Mr. Hsieh said he wanted to take the children out, but was refused.

July 5, 23:17:The defense presented Mr. Hsieh eating hot pot alone while crying to describe his loneliness, loss, and broken family relationships.

Purchase of three tools

Defense counsel showed the actual purchase inventory in court, but the observer could not record all the items, prices, and purchase times. This page does not fill them in independently and awaits the judgment or official transcript before supplementing them.

Other internet searches

The defense stated that besides looking up possible consequences of hitting someone, Mr. Hsieh also searched ordinary information such as part-time jobs. Not all search records could therefore be interpreted solely as part of a murder plan.

The defense also asked professional and citizen judges to be aware of their own emotions during deliberation, lest the brutal outcome, powerful stimuli, and controversy displace judgment of the legal requirements.

Emotional state during a crime can inform the court's understanding of intent formation and degree of responsibility. Emotion does not automatically exclude liability; it must be assessed together with preparation, purposefulness, and subsequent conduct.

• The case also included an attempted-offense component.
• It was not a killing following prolonged abuse of the victims.
• Although violent, the methods, the defense argued, did not reach the most extreme brutality among death-penalty cases.
• A complete murder plan had not formed at a very early stage and then been implemented step by step.

The defense argued that planned murder, as discussed by the Supreme Court, requires an explicit plan formed early and carried out accordingly. Heinous circumstances alone do not directly justify the harshest penalty. If correction and rehabilitation remain possible, imposing death is not necessarily required.

Citing the expert report, the defense said Mr. Hsieh's reoffending risk was moderate and could still decrease with appropriate treatment and corrective intervention.

The defense noted that a life sentence must be served for more than 25 years before parole eligibility is possible; it does not mean automatic release after 25 years.

The defense emphasized that Mr. Hsieh does not decide parole himself. The prison must submit the case based on imprisonment and treatment, followed by statutory review that may consider the victims' relatives' views. Authorities can deny parole if rehabilitation is ineffective or risk remains high.

The defense argued that children should retain the possibility of finding answers for themselves when they grow up.

The defense argued that even if the children choose to hate him in the future, Mr. Hsieh should remain alive to personally bear the hatred of the daughter he deeply loves, rather than death ending his possibility of facing responsibility.

This was the defense's value-based argument about the purposes of punishment. The court must independently balance culpability, general and specific prevention, victim impact, rehabilitation prospects, and constitutional requirements.

Public reports stated that the victims' relatives were emotional after the verdict and strongly dissatisfied that death had not been imposed. These notes respect their feelings and remind readers that the first-instance judgment was not final; appellate proceedings could follow.
