Sisaket police have made progress in the burial murder case of a 19-year-old whose body was concealed in a eucalyptus forest in Sisaket province. The chief of Phrai Bueng Police Station confirmed that three suspects aged 17 to 19 have been arrested. The motive stems from prior conflicts during their time in juvenile detention. The incident involved a scheduled meeting to settle disputes. Relatives of the victim and the injured have stated they will not forgive the perpetrators.
On 1 Mar 2026, the body of a teenage male was found buried in a eucalyptus forest area of Phrai Bueng district, Sisaket province. The autopsy revealed over 30 stab wounds from sharp objects. The victim was identified as Sitthisak, also known as Mix Tanpan, aged 19. Additionally, the victim's friend, Kittisak or On Donpaeng, also 19, was stabbed with sharp objects—two wounds under his right breast and four on his back—sustaining critical injuries. He was transferred to Sunpasitthiprasong Hospital in Ubon Ratchathani province, where his condition remains critical on life support and unconscious, as previously reported.
On 2 Mar 2026, reporters visited the home of On (the injured) in Ban Pun, Village No. 6, Phrai Subdistrict, Khun Han district, Sisaket province. Mrs. Buarun Supha, 51, On’s grandmother, told reporters she learned about On’s stabbing around 4 a.m. when On's mother came from Phrai Bueng Hospital informing relatives that On was critically injured. Initially, she thought On had gotten into a fight after attending a molam music event, not realizing he had been lured and attacked. On's mother said doctors gave a 50-50 prognosis, noting On was unconscious and unresponsive.
Normally, On has a good, obedient character, accepting his parents’ decisions. Four days earlier, Mix (the victim) ominously said, “If you don’t see me in four days, it means I’m gone,” a statement she never expected to foreshadow such a tragic event. She expressed deep sorrow and disbelief that her grandson was severely injured and that his friend was brutally killed so suddenly. She recalled seeing and talking with On daily, including On asking her for a cigarette just before the incident. She described the perpetrators as brazen, showing no fear of the law, and said if she met them, she would ask why they did not just hurt her grandson enough to teach him a lesson rather than killing him and burying his body.
Reporters then visited the home of Mix (the deceased) and met Mrs. Swee Tanpan, 59, Mix’s grandmother, who said she had raised Mix since infancy. Mix was quiet, well-behaved, and not aggressive. She last spoke with Mix two days prior when he took her to have a tooth extracted at the hospital. Upon returning home, she told Mix they would attend the village headman’s wedding the next day. However, Mix was killed before he could attend the wedding.
Regarding Mix’s military enlistment plans, Mrs. Swee said Mix was idle at home and wanted to volunteer for the military. She supported him and helped him apply. He was scheduled to report for duty in April. Before the incident, she had a premonition-like dream where her late mother offered her meat to eat, a dream she found unusual as it was the first time experiencing such a vision.
Mrs. Swee stated she does not forgive those who killed her grandson, describing the act as brutal and inhumane. If she met the perpetrators, she would ask why they harmed her grandson so severely. If there had been a dispute or if Mix had done wrong, why not resolve it through discipline or communication? She condemned the killers for their cold-heartedness in killing and burying Mix. She urged police to prosecute the suspects to the fullest extent.
Regarding the case, Pol. Col. Ratchayut Sakrapee, chief of Phrai Bueng Police Station, disclosed that all three suspects, youths from Mai Kaen village aged 17 to 19, have been arrested. They admitted the crime was linked to previous conflicts during their time at the Sisaket Juvenile Detention and Protection Center. The incident began with a scheduled meeting to settle issues, but the parties failed to reconcile, resulting in the three suspects committing the attack.
Pol. Col. Ratchayut added that the suspects had prior detention for attempted murder charges. Initially, investigators charged them with joint murder and concealing a corpse to hide the cause of death. The weapon recovered at the scene was a 24-centimeter long pointed knife, including the handle.
