A tense situation after a six-hour siege: "Lieutenant Oh" remains silent inside his home with no sign of surrender following the fatal shooting of his teacher wife at school. Police are preparing to revise their negotiation plan while waiting for his son to fly back from the south to assist in persuading him.
On 9 September 2026, developments continued regarding the siege of Lieutenant Thasaphong Thongthach, known as "Lieutenant Oh," age 55, deputy patrol officer at Bang Lamung Police Station. He barricaded himself inside his home in a village in Nong Plalai Subdistrict, Bang Lamung District, Chonburi Province, after committing a shocking act by shooting his wife, Ms. Phailin Thongthach, age 48, or "Teacher Ple," fatally in front of a classroom at Nong Plalai Municipal Kindergarten. During the siege and negotiation attempts, police commanders, veteran officers, and relatives have tried to communicate with him, but Lieutenant Oh shows no intention of surrendering.
Most recently, at 18:30, Police Major General Pongpan Wongmaneethes, Commander of Chonburi Provincial Police, maintained the perimeter around Lieutenant Oh’s residence. The house remained tightly closed, with all doors and windows covered with curtains to prevent visibility from outside. Police detected signs of life inside; Lieutenant Oh was seen pacing inside the house on both the ground and upper floors.
Meanwhile, the special operations unit of Chonburi Provincial Police made their third attempt at negotiation but were unsuccessful. Lieutenant Oh did not respond or engage in any communication. Police have invited his parents inside to persuade him to surrender.
Additionally, there are reports that his eldest son, who serves as a police officer in the southern region, is currently flying back to assist in persuading his father to surrender. It is expected he will arrive at the residence around 9 p.m. tonight.
Counting from when Lieutenant Oh shot his wife fatally at the school and then drove his white sedan back to his home at 10:57 a.m., until now, more than six hours have passed with no sign of surrender. Overall, the situation remains very tense, with multiple agencies coordinating to provide full support.
Police have requested lighting support from various agencies, including Nong Plalai Subdistrict Municipality and the Sawang Boriboon Thammasathan Foundation rescue unit of Pattaya City. Lighting vehicles and fire trucks have arrived at the scene. It is anticipated that the situation will likely extend into the late hours of tonight.
