Police Lieutenant Akrapong Saenputawong, Deputy Investigator at Pattaya City Police Station, responded to the report at 08:30 and attended the scene with forensic officers and rescue workers. Inside Room 202 on the third floor, there were no signs of a struggle or theft. Investigators found a bottle of Thai Sangsom liquor, a bottle of water and a glass on the bed, while the victim’s missing right trainer was later located in the corridor.
The victim’s partner, Ms Phantiwa Namboon, 39, from Ubon Ratchathani, told police she had been living with him since 14 March. She said she returned from work and found him sitting on the stairway near their room, initially believing he was asleep. After attempting to wake him without success, she called for help and discovered he had already died.
She stated that Mr O’Coyne had underlying health conditions, including high blood pressure and was a heavy daily drinker. He had resigned from his job as an online life insurance salesman two weeks earlier and was preparing to return to the UK for medical treatment. She added that he frequently vomited blood when intoxicated and had shown signs of confusion and memory loss prior to his death.
CCTV footage showed the man leaving his room at around 02:00 wearing only black shorts and appearing intoxicated, before returning to his room. At approximately 06:00, he sent a message to his partner expressing sadness and disappointment regarding family matters and his planned return to the UK. It was then later that he was found dead on the stairwell.
SiamRath reported that Police said no suspicious activity or third-party involvement had been identified from the CCTV footage. However, the exact cause of death and how the small head injury occurred, remains unclear and the body has been sent to the Institute of Forensic Medicine at Police General Hospital for a detailed autopsy. Authorities will continue their investigation and are awaiting forensic results to confirm the cause of death.
