Police and rescue workers arriving at the scene discovered the body of Nattapong Kliangpiboon, a senior prison department director, outside the house with a 9mm handgun lying beside him. Inside the residence, they found two other victims: Trakul Phanchai, the prison’s nursing director and Nattapong’s former wife, and Wichit Thongsing, a recently appointed prison warden who had been in a relationship with her.

Initial investigations revealed that the three had been engaged in a heated argument prior to the shooting. The confrontation escalated when Nattapong opened fire on the couple. Wichit reportedly returned fire using a .38-caliber handgun, leading to a brief exchange of gunshots. Both Trakul and Wichit sustained fatal wounds during the altercation, while Nattapong suffered minor injuries. Following the shootout, Nattapong died from a self-inflicted gunshot wound.
