The parents of product presenter Thitima "Lunlabelle" Noraphanpiphat have asked for a second autopsy, as they do not believe their daughter drank herself to death without outside help.
The grieving couple, accompanied by the deceased woman's three-year-old daughter, filed their request at the Justice Ministry on Thursday.
They want the ministry's Central Institute of Forensic Science to perform the second autopsy on their daughter's body. They are also seeking assistance from the ministry's compensation fund for victims of crime.
Supamas Noraphanpiphat, Thitima's mother, said her daughter would not willingly have drunk so much alcohol that it put her life at risk. There could be some truths yet to be discovered.
According to police, an autopsy performed by Chulalongkorn Hospital found that Thitima died of extreme alcohol intoxication with a blood alcohol concentration of 418 milligrammes per 100 millilitres - a level that causes unconsciousness and death.
Mrs Supamas said she and her husband were suspicious of the fact the clothing their daughter wore at the time of her death was disposed of.
The family met Thanakrit Jit-areerat, secretary to the justice minister, and Samart Jenchaijitwanit, vice minister of justice.
Mr Samart said the complaint centre of the Justice Ministry would contact the Central Institute of Forensic Science to discuss the issue, and the ministry would look into the possibility of arranging for compensation because Thitima was a breadwinner of her family.
Thitima, 25, was found dead on a sofa in the lobby of a condominium building on Ratchadaphisek-Tha Phra Road in Thon Buri district early on Sept 17. Surveillance camera footage showed she was carried into the building the previous evening by Rachadech, "Nam Oun" Wongtabutr, a work colleague who lived there. He also placed her on the sofa early the next morning.
She was hired to serve drinks at a party in a house in Bang Bua Thong district, Nonthaburi, on the afternoon of Sept 16.
Mr Rachadech, 25, was arrested on Wednesday and charged with detaining her in a manner that caused her death, detention for purposes of molestation, and molestation. He denied all charges.
On Thursday police took him to court and sought approval to further detain him while the investigation proceeds.
