Hernández, a reporter for the daily Noticias, Voz e Imagen de Oaxaca, was shot in the head with a 9mm pistol as he climbed into his car outside a bar in the municipality of San Andrés Huaxpaltepec, in the state of Oaxaca, according to his paper and other reports.
Ismael Sanmartín Hernández, the editorial director of Noticias, Voz e Imagen de Oaxaca, told CPJ that Hernández wrote about cacicazgos (local strongmen who rule parts of the region) and their alleged influence in local politics. "He was often in fear," Sanmartín said. He told CPJ Hernández had been working on sensitive stories and was afraid of reprisal.
Hernández, 38, was also a freelance correspondent at La Ke Buena radio in the municipality of Pinotepa Nacional, and at a community station in Santiago Jamiltepec, according to local news reports and a colleague at the paper, who spoke with CPJ. The colleague, who asked to remain anonymous out of fear of reprisals, said Hernández reported on social issues including poverty, education, and politics. He said Hernández had recently reported on protests over the construction of a dam. The colleague added that he did not know of any threats against Hernández, but said the journalist had been afraid over his reporting on sensitive issues.
A journalist familiar with the case, who asked to remain anonymous out of security concerns, told CPJ Hernández had been threatened over his reporting.
On February 25, police arrested the police commander of Santiago Jamiltepec, Jorge Armando Santiago Martínez, and charged him with the murder of Hernández, according to local news reports.
On March 3, 2017, a regional court in the coastal town of Puerto Escondido convicted Santiago Martínez of homicide and sentenced him to 30 years in prison. He was also ordered to pay 178,000 pesos in damages to Hernández's family, according to a statement from Oaxaca Attorney General's Office.
Sanmartín told CPJ Hernández was affiliated with the left-wing opposition political party MORENA, and was a municipal official responsible for culture in Santiago Jamiltepec.
A column published in Noticias, Voz e Imagen de Oaxaca on January 24, 2016 described Hernández as a brave reporter covering a region beset by political violence and, increasingly, drug cartels. "Time and again, Marcos Hernández Bautista, in the pages of Noticias, tirelessly revealed the true face of the coast; people's aspirations, their struggles and conflicts, not only with organized crime, but with the other powers that be and corrupt public functionaries suspected of being linked with narcotics trafficking activities," Amado Sanmartín Hernández wrote in the newspaper.
