Assailants left 10 beaten, murdered bodies in front of the governor’s office in the north-central Mexican state of Zacatecas on Thursday.

The bodies were crammed into a pickup truck left before dawn near a Christmas tree in the main plaza of the state capital, also named Zacatecas.

Gov. David Monreal said he was starting work when he got word of the grisly discovery.

“They came to leave them here … bodies, apparently beaten, with wounds,” Monreal said.
