Mexican drugs cartels are famous for ignoring authority and gruesome public killings but they seem to be taking things to new extremes.

Coppers have found a woman's decapitated body in a Mexican border city on Saturday, alongside a handwritten sign saying she was killed in retaliation for her postings on a social networking site. It is the third time in which people in Nuevo Laredo were killed by a drug cartel for what they said on the internet.

The victim was Marisol Macias Castaneda, a newsroom manager for the Nuevo Laredo newspaper Primera Hora. It looks like Mexico drug lords are concerned about an “Arab spring” against their rule of terror and want to silence Internet bloggers.

Castaneda held an administrative post, not a reporting job. She posted in Nuevo Laredo en Vivo which is used by the Mexican army, navy and police, and includes a section for reporting the location of drug gang lookouts and drug sales points.
Apparently she miffed the hyper-violent Zetas drug cartel, which is believed to dominate the city across from Laredo, Texas.
