The body of a Mexican journalist was found on Tuesday a week after going missing in the northern border state of Sonora, local authorities said, as the death toll for media workers in the country continues to rise.

Juan Arjon Lopez, who ran the Facebook webpage “A que le temes,” went missing on August 9, according to the state attorney general. A body with tattoos matching those of Arjon was recovered Tuesday in the town where he disappeared, San Luis Rio Colorado.

Arjon’s body was found showing “signs of violence,” Sonora Attorney General Claudia Indira said at a press conference.

“He had a webpage (where) he covered security topics, he was known and recognized in San Luis,” Balbina Flores of Reporters Without Borders said.

Human rights organization Article 19, which tracks murders of journalists, is looking into the case, a press representative said.

Mexico is one of the deadliest countries in the world for journalists, according to Article 19, which has counted at least 34 media workers killed in relation to their work since President Andres Manuel Lopez Obrador took office in December 2018.
