The Zetas drug cartel is believed to be behind the mass graves recently discovered in northern Mexico, authorities said Tuesday.
Mexican Attorney General Marisela Morales said that 116 bodies have been found and that 17 suspects have been detained in connection to the killings.
Authorities began finding the graves last week during an investigation into a report of the kidnapping of passengers from a bus in late March. The investigation led them to San Fernando, Mexico, the same place where the bodies of 72 immigrants were found at a ranch last August.
The Mexican state of Tamaulipas, where San Fernando is located, is one of Mexico's most active states when it comes to drug trafficking. The Zetas cartel and the Gulf cartel operate in the state and have strongholds there.FULL STORY
