She was with some colleagues at the party and one of them, Rommel Galida, woke up at around 10am to noticed that she asleep in the bathtub.
Mr Galida said that he covered her with a blanket before going back to bed and that when he woke up some hours later, he found her unconscious and started to turn blue.

She was then rushed to hospital where doctors confirmed her death.
Investigators said they are waiting for the autopsy report but hinted that the young woman’s body has bruises and cuts on her thighs and knees which suggests that might have been raped.
