Via the Guardian:
The woman, identified by local officials as Marisol Macías Castañeda, a newsroom manager for the Primera Hora newspaper, was found in Nuevo Laredo next to a handwritten note claiming she was murdered for posts about the Zetas cartel, which is believed to dominate the area’s drug trade to Laredo, Texas.
Macías Castañeda held an administrative post at Primera Hora, not a reporting job, according to a colleague who wished to remain anonymous. But it was apparently what she posted on the social networking site Nuevo Laredo en Vivo (Nuevo Laredo Live), rather than her role at the newspaper, that prompted her murder.
The site prominently features tip hotlines for the Mexican army, navy and police, and includes a section for reporting the location of drug gang lookouts and drug sales points – possibly the information that angered the cartel.
The message found next to her body on the side of a main road referred to the nickname Macías Castañeda purportedly used on the site, La Nena de Laredo (Laredo Girl). Her head was found placed on a large stone piling nearby.
"Nuevo Laredo en Vivo and social networking sites, I’m The Laredo Girl, and I’m here because of my reports, and yours," the message read. "For those who don’t want to believe, this happened to me because of my actions, for believing in the army and the navy. Thank you for your attention, respectfully, Laredo Girl…ZZZZ."
