The 2011 San Fernando massacre, also known as the second massacre of San Fernando, was the mass murder of 193 people by Los Zetas drug cartel at La Joya ranch in the municipality of San Fernando, Tamaulipas, Mexico.[2] Authorities investigating the massacre reported numerous hijackings of passenger buses on Mexican Federal Highway 101 in San Fernando, and the kidnapped victims were later killed and buried in 47 clandestine mass graves.[2] The investigations began immediately after several suitcases and baggage were unclaimed in Reynosa and Matamoros, Tamaulipas.[3] On April 6, 2011, the Mexican authorities exhumed 59 corpses from eight mass graves.[4] By 7 June 2011, after a series of multiple excavations, a total of 193 bodies were exhumed from mass graves in San Fernando.[5]
