MORELIA, Mexico : The bodies of 16 people have been found in two mass graves in two Mexican states torn by drug-related violence, state authorities. Thirteen bodies were uncovered in the western state of Michoacan, and three more in Sinaloa in the northwest. In the larger find, the bodies of six men, five women and two minors were uncovered. Their identities were not immediately known but preliminary investigation suggests they were members of a family abducted back in August by gunmen.

The bodies were found near Apatzingan, the commercial hub of a region call Tierra Caliente, where the vigilante groups formed started to form a year ago to defend themselves from killings, extortion and kidnappings by the Knights Templar drug cartel.
