Mexican authorities say they have arrested an alleged drug trafficker as a suspect in the killing of the Sicilia's only child. Sicilia's son, Juan, and six friends were abducted by gunmen while leaving a nightclub in Cuernavaca, and their bodies were found abandoned near the city. The killing led Sicilia to become a vocal critic of the Mexican government's military crackdown on drug cartels. (AP Photo/Eduardo Verdugo, File)
