A Mayor in the central San Luis Potosi state of Mexico, Jesus Eduardo Franco, who was a member of the ruling Morena party, was shot dead on Sunday along with three other people.
Franco and the three other victims were all found dead inside a vehicle, according to the state prosecutor’s office.
“We deeply regret the death of our colleague Eduardo Franco, municipal president of Tancanhuitz,” Morena party president Rita Rodriguez wrote on X (formerly Twitter).
“We ask authorities to reach the ultimate consequences and find those responsible,” she added.
Dozens of local officials have been targeted in organised crime-related violence that has plagued Mexico in recent years.
Local media reported last month that Alejandro Arcos, a mayor in southern Guerrero state, was decapitated less than a week after taking office and his head placed on top of a pickup truck.
