Authorities have found the remains of 167 people, believed to be at least 50 years old, in the southern Mexican state of Chiapas, officials said.
The remains were discovered inside a cave on the Nuevo Ojo de Agua ranch, and show no visible signs of violence, according to a statement from state prosecutors.
Studies will be done to determine the age, sex and cause of death of each person, it read. The prosecutors promised not to rule out "any line of investigation."
Though the remains are thought to be more than half a century old, the discovery is still sure to attract attention in a country where mass graves have been unearthed in recent years.FULL STORY
