Police in Mexico’s northwestern Sinaloa state have found the half-buried and bullet-riddled body of a local magazine editor missing since Oct. 10.

The body of Antonio Gamboa Urias was found Oct. 23. Gamboa had been abducted and killed after an argument in a bar, press freedom group Reporters Without Borders said, citing a Sinaloa state prosecutor. Five suspects have been arrested in the case and statements from those detained helped police find the body, Agence France-Presse reported.

The prosecutor’s narrative of events appears to rule out a connection between Gamboa’s work and his death. However state prosecutors have not responded to queries about the case from a federal prosecutor charged with investigating crimes against freedom of expression, Reporters Without Borders said.

Gamboa had edited the magazine Nueva Prensa, a magazine that covered topics including corruption in the Sinaloa city of Ahome, 780 miles (1,255 kilometers) northwest of Mexico City. He was among a group of journalists that protested a proposed “Ley Mordaza,” or gag law, that would have restricted coverage of crime in Sinaloa, according to the website Periodistas en Espanol.

Gamboa is the seventh media worker killed in Mexico in 2014.
