Mexico announced that it has in custofy Vicente Carrillo Leyva, who allegedly was the second in command of the Juarez cartel. The announcement came hours before the Obama administration's top security officials and their Mexican counterparts were set to discuss ways to stop arms smuggling across the border as well as new strategies for fighting the drug cartels that have fueled violence in both countries. Carrillo Leyva, 32, was caught while he was exercising in a park in a posh Mexico City neighborhood early Wednesday. Carrillo Leyva is the son of drug kingpin Amado Carrillo Fuentes, who was one of Mexico's most important drug traffickers before he died during plastic surgery to change his appearance in 1997.
