The three women accused of murdering and dismembering a karaoke club singer will have a psychiatric interview after they showed signs of stress during an initial physical examination when they arrived at Khon Kaen Prison.
Prison director Weerachai Phetcharat said the detainees wept during their physicals and while they were questioned about personal information.
Weerachai said the three shared a detention cell for the first night of incarceration but they would be held in separate cells starting yesterday, he said.
Each woman was being supervised by two guards to prevent any suicide attempt, he added.
The director said that he had asked for a psychiatrist from Khon Kaen Rajanagarindra Psychiatric Hospital to meet the women and assess the state of their mental health.
Priyanuch Nonwangchai, 24, Kawita Rachada, 26, and Apiwan Satayabundit, 28, turned themselves in to Myanmar authorities on Saturday and were handed over to Thai police on suspicion of murdering Warisara Klinjui, 22, in Khon Kaen late last month.
The three women were forced to re-enact the crime on Monday before being taken to a provincial prison.
At least one of the women has confessed to the crime.
Weerachai said the women were healthy and Priyanuch and Kawita passed drug tests.
However, Apiwan's urine test showed signs of having taken drugs, which she reportedly did in Myanmar five days ago.
Apiwan's father and relatives yesterday visited her at the prison.
"Our whole family is sad. We had never thought things would come to this point," said her father.
Priyanuch's mother and elder sister also showed up at the prison but were denied a visit because they could not produce all the required documents.
