Villas de Salvárcar Massacre: 16 Teenagers Killed at Party in Juárez

Gunmen storm a house party in the working-class Villas de Salvárcar neighborhood of Ciudad Juárez and execute 16 teenagers, most of them high school students. Calderón initially dismisses the victims as gang members from a distance while attending a World Economic Forum event in Davos, Switzerland — a response that triggers intense public outrage. He later apologizes and flies to Juárez to meet victims' families.
