The body of Humphan Chancharoen, 23, was found at 9.30pm. Muang Phayao police also found spent ammunition shells from a .38-millimetre gun at the scene and another spent shell in the room where he lived in the workers' quarters.
Thongpoon Panya, the shop owner who lives in a house about 20 metres away from the shop, said he heard two gunshots about ten minutes apart and that Pun Jaima, one of Humphan’s work colleagues from Chiang Rai, had since gone missing.
Police believe Pun shot Humphan in his room and then followed him to the warehouse, where he shot him again.
Police are now searching for Pun.
