Following an anonymous tip, Mexico’s Prosecutor General of the Republic (PGR) arrested three suspected members of the narco-paramilitary group Los Zetas Sept. 25 as the “material authors” of the Independence Day grenade attack that left eight dead and over 100 injured in Morelia, Michoacán. Four more are under investigation in the attack and may face imminent arrest, said Marisela Morales Ibáñez, chief of the Special Investigative Subprosecutor for Organized Delinquency (SIEDO). Morales Ibáñez emphasized that the men, detained at a house in the Michoacán city of Apatzingán, were themselves on drugs when they carried out the attack. The arrested suspects were named as Julio César (“Tierra Caliente”) Mondragón Mendoza, Juan Carlos (“El Grande”) Castro Galeana, and Alfredo (“El Socio” or “El Valiente”) Rosas Elicea.
