The family of contractor Chuwong Sae Tang, who supposedly died in a car crash in June last year, claimed Monday that an independent review of the autopsy report suggested the billionaire's death was not an accident.
Two bones in Chuwong's neck were broken due to impact caused by a hard object, the Medical Council of Thailand (MCT) revealed Monday.
Chuwong's family had asked the MCT to review the autopsy findings from the Police General Hospital's Institute of Forensic Medicine.
The family said the autopsy report was incomplete, with crucial details missing.
MCT president Somsak Lolekha said the council referred the report to the Royal College of Pathologists of Thailand, which set up a panel to examine it. Forensic experts were also invited to analyse the report.
Dr Somsak said Chuwong's relatives had doubts about the autopsy report, including what caused Chuwong's eyes to bleed.
This was caused by impact from a hard and blunt object while a chin wound resulted from his chin scraping on a rough surface, he said.
The panel also found the sixth and seventh neck vertebrae were broken as a result of an impact from a hard and blunt object, Dr Somsak said. The second and third vertebrae were the ones most often broken in accidents, he said. Dr Somsak said the panel could not say what object broke the bones.
Chuwong's family said the findings will be handed to the Crime Suppression Division in the next few days. CSD deputy chief Pol Col Nos Sawetlek said the cause of death is still unclear.
Following the death, it was revealed that Chuwong's signature was on papers transferring shares and cash to two young women.
The transactions raised suspicions of Chuwong's wife and children that his death may not have been accidental.
