Supat Laohawattana, a former Police General Hospital doctor, will face murder charges if DNA taken from one of three human skeletons dug up from his Phetchaburi orchard matches that taken from the mother and the son of the alleged victim.
A key witness who worked at the pineapple orchard said one of the three skeletons belonged to Ita, a Myanmar worker, who was allegedly shot dead by Pol Col Supat, said Pol Lt Gen Harnpol Nitwibul, chief of the Provincial Police Region 7.
Ita's mother and his son have been brought from Myanmar to undergo DNA tests in Thailand. If the DNA from the two matches that taken from the skeleton, police will press murder charges against Pol Col Supat, said Pol Lt Gen Harnpol.
Pol Col Supat, who formerly worked at the Police General Hospital, is suspected of killing a couple who have been missing since 2009 and at least two Myanmar migrant workers who were employed at his orchard.
So far, police have not yet found the bodies of the missing couple _ Samart Noomjui and his wife Orasa Kerdsap.
Testimony given by the witness led police to believe that the couple were dead, provincial police said.
