A municipal official reported missing earlier this week was found with his throat slit, authorities in the western Mexican state of Michoacan said.

Clemente Mendez, 47, was discovered after police received a report about a dead body lying on a field outside the town of Taretan, the state Attorney General's Office said.

Mendez, a member of Mexico's ruling Institutional Revolutionary Party, or PRI, was Taretan's planning chief and oversaw the municipal budget.

The slash to the victim's throat "apparently caused instant death," the Michoacan AG's office said, adding that authorities were still working to determine a motive for the killing. EFE
