(AP Photo/Alexandre Meneghini) Mexico has busted an army deserter who helped found one of the country's most powerful drug cartels. Jesus Rejon Aguilar—alias "El Mamito" or "Pretty Boy"—was third in command of the Zetas drug cartel and is suspected of crimes including the killing of a US customs agent in northern Mexico earlier this year, reports the Los Angeles Times. Rejon served in a special forces unit before founding the Zetas with fellow ex-soldiers in 1999. The organization started out as the Gulf Cartel's military wing before breaking away to become a drug cartel itself, sparking a feud that has been among the deadliest in Mexico's drug war. Police say Rejon was captured without a shot being fired. Read These Next Lindsey Graham says he's never heard Trump so angry. Trump reveals a GOP lawmaker's previously private diagnosis.
