She was wearing a brown long-sleeved T-shirt and had an eagle tattoo on her left leg. Police could not yet determine the age and nationalities of the deceased. The bodies were sent to Police General Hospital in Bangkok for autopsy. Koh Sak is about 10 km west of Pattaya, and 600 metres from Koh Larn.
