Police initially suspected that the killings might have stemmed from drug trafficking or the ongoing unrest in the deep South.
Lieutenant Preecha Prachumchai from Khok Pho Police Station led the forensic officers to inspect the scene where unknown armed men, wearing hoods and black clothing, opened fire on the villagers while they were reportedly drinking Krathom tea at the house in Tambon Na Pradu.
Two villagers fled the scene.
