The body of Regina Martinez, the Proceso magazine correspondent in the eastern Mexican state of Veracruz, was found in her house, officials said.
Martinez, who covered drug trafficking, was found Saturday in the bathroom of her house in Xalapa, the capital of Veracruz, and appeared to have been beaten and strangled.
Emergency services personnel found the body around 6:00 p.m. after responding to an anonymous tip about a dead body.
Veracruz Gov. Gabriel Duarte ordered an investigation to determine who killed the reporter and expressed his condolences to her family.
Martinez had worked for a number of different media outlets during a career that spanned more than 30 years.
Mexico, where nearly 80 journalists have been murdered and several others have disappeared since 2000, is considered the world’s second most dangerous country for members of the media.
Nine journalists were murdered in Mexico last year, the National Human Rights Commission, or CNDH, said in a statement released in January.
Journalists have increasingly been targeted in recent years by drug traffickers and other organized crime groups, especially in northern Mexico.
Media members must also contend with long-running abuse at the hands of federal, state and local officials.
Veracruz has been plagued by a turf war between rival drug cartels that has sent the state’s murder rate skyrocketing.
Residents of Veracruz city were stunned on Sept. 20 by the discovery of 35 bodies dumped on a busy thoroughfare.
A week later, 32 bodies were found at three drug-gang “safe houses” in the Veracruz-Boca del Rio metro area.
The Gulf, Los Zetas and relatively new Jalisco Nueva Generacion cartels, as well as breakaway members of the once-powerful La Familia Michoacana organization, are fueling the violence in Veracruz, which is Mexico’s third-most populous state and coveted as a key drug-trafficking corridor to the United States, officials say.
