Perea Quintanilla had 20 years of experience as a crime reporter, since he had worked for the dailies El Heraldo de Chihuahua and El Diario de Chihuahua before deciding to create his own magazine, Dos Caras, Una Verdad (Two Sides, One Truth), in 2005 [REF].
Prior to his assassination, Perea Quintanilla wrote in his last column that Dos Caras, Una Verdad had several video clips, photos, and documents sufficiently in detail to supposedly inculpate various politicians and officials in the government, including the then-governor of Chihuahua, José Reyes Baeza Terrazas [REF].
