Roh’s mother reported the incident to the South Korean embassy in Thailand to coordinate with Thai police for immediate action.
Roh’s wife, who is a Thai national, said that she had last seen Roh on May 2 at a nightclub in the RCA area of Bangkok. Upon reviewing CCTV footage, it was found that on May 2, at around 2am, two men had taken Roh away in a rented car that headed towards Pattaya, where they switched to a pickup truck and then checked into an accommodation near the Mabprachan Reservoir in Pattaya.
On May 4, at around 9pm, the pickup truck was seen leaving the accommodation, covered with a black cloth. Subsequently, the Koreans purchased a black plastic barrel and ropes from a store, presumably to dispose of the body. Upon investigation, it was found that the pickup truck had parked near the Mabprachan Reservoir for around an hour before returning to the rented accommodation.
