Extreme alcohol intoxication caused the death of Thitima Noraphanpiphat, a "pretty" better known as Lunlabelle, police said on Monday, announcing the preliminary results of the autopsy.
Police on Monday announced the preliminary findings of the autopsy, saying she died of alcohol poisoning. No other fluids were found and there was no evidence of assault.
A police source said she had a blood alcohol level of 418 milligrammes per 100 millilitres - a level that can cause unconsciousness and death.
The 25-year-old product presenter was found dead on Tuesday morning in the lobby of a condominium building in Talat Phlu area where her co-worker Rachadech "Nam Oun" Wongtabutr lives.
Security camera footage showed Mr Rachadech entering the building last Monday evening with the apparently unconscious woman and taking her up to his room on the sixth floor. Hours later he carried her back into the lobby and placed her on a sofa.
Mr Rachadech told police he and Thitima were earlier at a party where she was paid to serve drinks at a house in Bang Bua Thong district, Nonthaburi. He admitted taking her to his room, but said they were both drunk and nothing occurred there.
Police on Monday refused to say if Mr Rachadech was the only suspect in the case, but said more people would be arrested if the evidence justified it.
A charge of murder was also possible as the suspect failed to help Thitima when her life was in danger, police added.
Lunlabelle's father, Mr Chavalit, on Monday gave Bukkhalo police, who are handling the investigation, one of his daughter's bras, to be used to compare with other items of evidence.
