Although investigators collected DNA samples at the time, no progress was made and the DSI took up the case six years ago. DSI chief Pol Lt-Colonel Paisit Wongmueng said the DSI had recently received a tip-off that a Japanese man had been in the area 10 years ago, which made him a person of interest in the case. Phaisit said the DSI would seek cooperation from the Japanese Embassy to contact Japanese authorities to seek a DNA sample from the man to compare with the sample from the victim. Phaisit said DSI officials had sought to collect evidence in Sukhothai after assuming responsibility for the case six years ago. He said the victim’s parents had asked the DSI to increase the reward to encourage people to come forward.
