The 150-centimetre-tall victim sustained blunt force trauma to the head and had bruising on the right inner thigh and on the back of both hands as well as cuts on both thighs, possibly as a result of the body being hit by boat propellers, the source said.

Investigators had the medical examiner collect the victim’s fingerprints to check them against fingerprints contained in the Provincial Administration Department’s database.

Deputy police spokesman Maj-General Songpol Wattanachai said that Bang Saothong precinct police investigators were gathering evidences to identify the victim.

He said the autopsy results, expected in 10 days, would determine if the girl had been raped.
