The mass shooting happened about 10 minutes after midnight when the family was attending a New Year’s Eve party in Phato District, which is located in Chumphon Province in southern Thailand.
Police said the suspect, Sucheep Sornsung, became angry because he did not feel welcomed by his wife’s family and felt he was being ignored. He took out his gun when they were sitting at a table and opened fire.
The attacker shot and killed six people, including his nine-year-old son, his six-year-old daughter. Four adults between the ages of 47 and 71 were also killed. Sornsung then committed suicide by turning the gun on himself.
