MEXICO CITY (AP) — Investigators said Thursday they have found 166 skulls in clandestine burial pits in the Gulf coast state of Veracruz, one of the biggest mass graves discovered so far in Mexico.

Veracruz state prosecutor Jorge Winckler said that for security reasons he would not reveal the location of the site.

Mexican drug cartels frequently use clandestine pits to dispose of their victims.

Winckler said the bodies were buried at least two years ago and did not rule out finding more remains. He said investigators had found 114 ID cards in the field, which held about 32 burial pits.
