The body of Wan (no surname) with multiple cuts to her face and neck was found on the bank of the Huang River under the Huay Pa Chee Bridge in Ban Na Kha village in Tambon Pak Mon at 2.30pm.
A doctor determined she had been dead for about six hours.
She suffered a cut to her left ear, another to her left cheek and two cuts to her neck.
She still had about 70 lottery tickets and Bt4,000 in cash with her.
Her motorcycle was parked about 150 metres away.
Her Lao friend, Boom, 53, told police that Wan came to Thailand about four months ago to sell lottery tickets.
Police suspected that Wan had stopped there to change her napkin as she was having period, and that someone she knew well, perhaps her pillion rider, took the chance to kill her before fleeing the scene. Police have yet to identify a suspect.
