Catholic priest Marcelo Perez, an activist for Indigenous peoples and farm laborers in southern Mexico, was killed on Sunday.
The prosecutors' office in the city of San Cristobal de las Casas, in the state of Chiapas, said the religious leader was shot dead by two gunmen when he was in his van.
Perez was a member of the Tzotzil Indigenous people and had just finished serving a Mass when he was attacked. He served the community for two decades and was known as a negotiator in conflicts in a mountainous region of Chiapas where crime, violence and land disputes are rife.
Perez also led several marches against violence, which has brought him several death threats.
Chipas Gov. Rutilio Escandon posted on X that he condemned "the cowardly assassination of father Marcelo Perez.
"We will collaborate with all the authorities so his death doesn't go unpunished and those guilty face the courts," Escandon said.
