A school principal in southern Thailand died early Thursday from gunshot wounds sustained when a 17-year-old armed with a stolen police firearm stormed her campus, took hostages, and opened fire, the latest episode of gun violence in a country where firearms are widespread and mass shootings have repeatedly shocked communities.
Sasiphat Sinsamosorn, who served as both teacher and director at Patongprathankiriwat School in Songkhla province’s Hat Yai district, was pronounced dead at 2:06 a.m. at Hat Yai Hospital after undergoing emergency surgery for a gunshot wound to her left chest that caused severe internal organ damage and blood loss. Two female students were also injured, one shot in the waist, the other hurt jumping from a second-floor window while fleeing, during Wednesday afternoon’s siege that ended when the teenage gunman surrendered to police after holding victims hostage for hours inside the school building.
Authorities identified the suspect as a 17-year-old boy with a history of psychiatric treatment for substance abuse who was discharged from hospital in December.
Provincial officials said he entered the school “in an agitated state and armed with a firearm” around 4 p.m. Wednesday, though investigations continue into his motive and whether the attack targeted specific individuals or represented random violence driven by mental health crisis.

The rampage began earlier that afternoon when police received reports at 2:54 p.m. of a young man armed with a machete in the Thung Lung area near Hat Yai. Officers and a village headman responded but were forced to flee when the suspect chased and attacked them with the blade, according to police accounts of the chaotic sequence. He then ran approximately 200 meters to a police patrol vehicle, opened the door, and seized a 9mm pistol stored inside before firing at officers and forcing them to take cover, a confrontation that provided him the weapon later used in the school shooting.
Around 4 p.m., the armed teenager rode a motorcycle to Patongprathankiriwat School, where his younger sister was enrolled, and entered the campus. Witnesses reported he appeared agitated and was seeking a teacher who had previously disciplined his sister, according to Bangkok Post accounts that could not be independently verified. When the teacher he allegedly sought could not be found or refused to meet him, he shot Principal Sinsamosorn and took her along with several students hostage inside a classroom, threatening further violence while police surrounded the building and attempted negotiations.
The siege lasted several hours before the suspect surrendered without additional shootings, though three people required hospitalization for injuries sustained during the attack and escape attempts. Sinsamosorn, 48, was transported to Hat Yai Hospital in critical condition with a chest wound that surgeons worked through the night to repair, but she succumbed to massive blood loss and organ damage shortly after 2 a.m. Thursday. Her death was confirmed by the Mitraphap Samakkhi Foundation and the Secondary Educational Service Area Office of Songkhla and Satun.
Officials identified the injured students as Nattawan Thongphasmkaew, a 16-year-old girl shot in the left side of her waist who was transported to Songklanagarind Hospital and reported in safe condition following treatment, and Manassanum Anyphonphalakarn, 19, who sustained injuries to her chin and neck after jumping from the second floor of the school building in panic amid the shooting. The suspect was also injured during the incident, circumstances of how remain unclear, and received treatment at Hat Yai Hospital before police questioning.

Because he is a minor, authorities said a multidisciplinary team including mental health professionals, social workers, and legal specialists will be involved in his care and the investigative process to determine appropriate charges and whether he should face trial as a juvenile or adult given the severity of the crime.
Thai law permits trying minors as adults for certain serious offenses including murder, though prosecutors must petition courts for such designation and demonstrate the suspect’s maturity level and crime circumstances warrant adult criminal responsibility.
The school posted a message of condolence on its Facebook page honoring Sinsamosorn’s memory. “Although we have lost you, the memories and the goodness you left behind will remain in our heart forever,” the statement said, describing her as a dedicated educator who cared deeply for students and worked tirelessly to improve the school she led. Colleagues and parents expressed shock that violence had invaded a campus known for its safe, nurturing environment and tight-knit community atmosphere.
Education Minister Narumon Pinyosinwat presided over a formal funeral rite bathing ceremony for Sinsamosorn at 4:30 p.m. Thursday, a traditional Buddhist ritual honoring the deceased that the provincial government organized to recognize her public service and sacrifice.
The Ministry of Education said it is preparing to propose a special salary promotion and request the bestowal of a royal decoration for Sinsamosorn, posthumous honors typically reserved for public servants who die performing their duties or demonstrate extraordinary courage and dedication.
Gun violence and ownership are not uncommon in Thailand, where both legal and illegal firearms are widespread despite regulations requiring licenses and background checks. The country has experienced several high-profile mass shootings in recent years that have prompted calls for stricter gun control but limited legislative action, with powerful interest groups and cultural factors complicating reform efforts similar to debates in the United States and other countries grappling with gun violence epidemics.
In 2022, a former police officer killed 36 people, including 22 children, in a gun-and-knife attack at a nursery in Nong Bua Lamphu province in northeastern Thailand, a massacre that ranked among the deadliest such incidents in the country’s history and shocked the nation with its brutality and the killer’s targeting of preschool-age victims. That attack renewed demands for comprehensive gun law reform and improved mental health screening for firearm license applicants, though substantive changes have not materialized and guns remain readily available through legal channels and black markets.
Last year, a shooting at a Bangkok food market killed five people, while a 2023 incident at a shopping mall carried out by a teenage gunman added to Thailand’s growing list of mass casualty gun attacks that public safety advocates say reflect inadequate regulation, insufficient mental health resources, and a culture that normalizes firearm possession without adequate safety training or secure storage requirements.
Thailand has approximately 10 million registered firearms among its 70 million population, a ratio far lower than the United States but higher than many Asian neighbors including Japan, Singapore, and South Korea where strict gun control produces dramatically lower violence rates.
Police have not shared detailed information about the suspect’s background beyond confirming his age, psychiatric history, and substance abuse treatment, leaving unclear what specific mental health diagnoses he carried, what substances he abused, why he was discharged from hospital in December, and whether warning signs existed that might have prevented Wednesday’s attack through intervention or involuntary commitment. Thai law permits involuntary psychiatric hospitalization for individuals deemed dangerous to themselves or others, but criteria and enforcement vary and families often struggle to obtain help for relatives experiencing mental health crises.
