Mystery over dead turtles

MEXICAN environmental authorities are investigating the deaths of more than 100 endangered sea turtles whose carcasses have turned up at a wildlife sanctuary on the Pacific coast of Chiapas state.

The environmental protection agency on Saturday said 102 olive ridley, six hawksbill and five Galapagos green bill turtles were found dead at the Playas de Puerto Arista Sanctuary between July 24 and August 13.

Authorities were testing the water and conducting autopsies to determine possible causes of death.
