A body was found on Saturday floating off a beach in Bajos de Chila.
The victim is believed to be a woman but no further information has been revealed.
According to fishermen and maritime authorities, there have been no missing persons reports in the area, so any leads toward identifying the corpse remain scant.
Fishermen and navy personnel transported the body to the municipal morgue in Chila, where a necropsy was to be carried out.
Just over a month ago, a similar incident was reported in the water near Zicatela and Marinero beaches in Puerto Escondido.
