A man ambushed his former wife and her new partner in a residential neighborhood of Bangkok, shooting both before turning the weapon on himself in a murder-suicide that has refocused attention on escalating domestic violence across the capital. The Thailand Royal Police Min Buri division is treating the case as a jealousy-driven crime that unfolded in front of family witnesses.
Why This Matters
• Fatalities: Two dead, one critically injured in Bang Chan (Khlong Sam Wa district) on July 5.
• Rising Pattern: Domestic violence incidents in Bangkok place the city among the 4 provinces with the highest murder-suicide rates nationwide—250 cases in fiscal 2025 alone.
• Legal Recourse: Victims and witnesses are legally required to report domestic violence under the 2007 Family Violence Protection Act; failure to seek help can escalate to fatal outcomes.
The Incident
Officers from the Thailand Min Buri Police Station arrived at a two-story townhouse on Hathai Rat 39 alley shortly after 2:00 p.m. on Sunday following reports of gunfire. Inside, they discovered two bodies and a third victim hemorrhaging from gunshot wounds.
The deceased were identified as 35-year-old Rangsarn (also known as "Ball"), a delivery rider, and 36-year-old Piyanuch, his former common-law wife. The injured man, 30-year-old Worachot, Piyanuch's current boyfriend, sustained gunshot wounds to the lower back and was rushed to Sin Patya Serirak Hospital in critical condition.
Forensic teams recovered a .380-caliber semi-automatic pistol near Rangsarn's body, along with four spent shell casings scattered across the living room floor. According to police ballistics analysis, multiple rounds were discharged in rapid succession.
How It Unfolded
Rangsarn had arrived at the residence earlier in the afternoon under the pretense of collecting belongings from his child's second-floor bedroom. Piyanuch's mother, who was present in the home, granted him access. After descending the stairs, he reportedly pulled the handgun from a shoulder bag and opened fire. He then turned the weapon on Piyanuch before fatally shooting himself in the same location.
The sequence occurred in full view of family members, according to witness statements compiled by Bangkok Metropolitan Police investigators.
The Backstory
Rangsarn and Piyanuch had cohabitated for several years and shared a young son. Two to three months before the shooting, Rangsarn learned that Piyanuch had begun a relationship with Worachot, triggering violent arguments. Piyanuch subsequently moved back to her mother's home in Bang Chan, bringing Worachot with her—a development that sources say caused mounting psychological distress for Rangsarn.
On the morning of the incident, Rangsarn had volunteered to drive his mother and son to Nonthaburi province to collect a lottery quota. He falsely claimed he was planning a trip to Phuket afterward. After dropping them at the Mo Chit bus terminal, he diverted immediately to Piyanuch's residence, suggesting premeditation.
What This Means for Residents
Bangkok continues to rank among Thailand's most dangerous metropolitan areas for intimate-partner violence. According to the Thailand Ministry of Social Development and Human Security, the country logged an average of 42 domestic violence cases daily in 2024, with family-related violence accounting for 4,833 incidents—a rise of eight cases per day compared to the previous year.
Relationship disputes are the leading cause of completed suicides in Thailand, responsible for 48.7% of cases nationwide. Jealousy and romantic conflict alone account for 22.9% of self-inflicted deaths. The National Suicide Prevention Center recorded 5,172 suicide fatalities in fiscal 2023, or 14 deaths per day.
Available Support Channels
Residents experiencing or witnessing domestic violence can access multiple emergency services:
• Social Emergency Hotline 1300: 24-hour dispatch for mobile crisis teams operated by the Thailand Ministry of Social Development and Human Security. Thai language; English-speaking operators available.
• ESS Help Me (LINE: @esshelpme): GPS-enabled app that shares real-time location coordinates with police and social workers. Multilingual support available.
• Pavena Foundation for Children and Women (1134 or 02-577-0500): Legal aid, shelter, and medical referrals for survivors. English support available by request.
• Friends of Women Foundation (02-513-2780): Safe housing and victim advocacy, including services for sexual assault survivors. Thai language; translation assistance available.
Under the Family Violence Protection Act of 2007, both victims and witnesses have a statutory obligation to report incidents to authorities. Hospitals in Bangkok are required to document injuries and preserve forensic evidence, including photographs, audio recordings, and clothing, which can be used in criminal proceedings.
Broader Context
The Foundation for Women's Progress documented 1,131 domestic violence incidents reported through media channels in 2022—a three-fold increase from 2021. Of those, 534 cases (47.2%) resulted in homicide. Alcohol was a contributing factor in 29.1% of incidents, and illicit substances in 26.1%.
A December 2025 academic survey found that domestic violence in Thailand had climbed by 37% year-over-year, with some victims subjected to as many as 14 distinct forms of abuse—physical, psychological, economic, and sexual—by family members.
Bangkok's true suicide and domestic homicide figures may be underreported, according to a 2019–2020 Ministry of Public Health audit, because many hospitals in the capital operate outside the ministry's jurisdiction and do not systematically transmit data to national registries.
What to Do If You or Someone You Know Is at Risk
Exit the scene immediately if violence is imminent.
Call emergency services: Dial 191 for police or 1300 for social crisis intervention.
Seek medical attention: Do not shower, change clothes, or discard evidence before a forensic examination.
File a police report at the station nearest the incident location.
Document everything: Preserve text messages, voicemails, and photographs of injuries.
Contact a legal or social service organization for shelter referrals, restraining orders, and counseling.
Violence within families is not a private matter under Thailand law—it is a criminal offense that triggers mandatory reporting obligations and access to state-funded victim services. Early intervention remains the most effective tool for preventing escalation to homicide or suicide.
