Javier Valdez Cárdenas was shot and killed on May 15 near the offices of Ríodoce, the local weekly he founded in 2003 in Culiacán, the capital of Sinaloa state, according to media reports.
Armed assailants blocked Valdez's way shortly after he drove away from the office, dragged him out of the car, shot him, and used the car to get away, according to a report in Riodoce.
Valdez, who received CPJ's International Press Freedom Award in 2011, was also a correspondent for the daily La Jornada. He covered drug trafficking and crime, and wrote several books about the drug trade.
Valdez told CPJ in March 2017 that he was concerned for his safety.
