Enrique Villicaña Palomares, a columnist with the Voice of Michoacan newspaper, was reported missing late last week after failing to arrive for a university writing course that he teaches, APA reports. The reporter’s body was found with his throat slit on Saturday in the Michoacan state capital, Morelia , federal prosecutors were quoted by AP as saying. Investigators have yet to establish whether his murder was in relation to his work as a journalist.

“We condemn the brutal murder of Enrique Villicaña Palomares, and call on the Mexican authorities to promptly investigate whether Mr. Villicaña’s death was linked to his work,” said IPI Press Freedom Manager Anthony Mills . “Journalists are now being murdered with such chilling regularity in Mexico that the world risks becoming inured to their killings. This must not be allowed to happen. The Mexican government must do everything in its power to end this shameful epidemic of journalist murders.”

Villicaña’s family told press freedom observers that the journalist had reported on attacks by armed groups against the Purepecha indigenous group, of which he was also a member.

Villicaña is the fifth journalist in Mexico to be killed this year, according to the IPI Death Watch. Most were murdered in connection with their reporting on drug crime.
