Hernández, a police reporter for the magazine Como, was hit on the head with a blunt instrument on July 25 and died the next day. Hernández was attacked after leaving the office of the Federal Judicial Police, where he had gone to work on a story. Colleagues at Como suspect that federal agents working for the judiciary or individuals connected to the police may have killed him. Hernández often covered stories on the police and drug trafficking. He had received threats and was the target of an attempted car bombing.
