Arturo Beltrán Leyva 'El Jefe de Jefes' Killed in Cuernavaca

In a four-hour gun and grenade battle at a luxury apartment complex in Cuernavaca, Mexican Marines — acting on US intelligence — kill Arturo Beltrán Leyva and four bodyguards. Beltrán Leyva, known as 'The Boss of Bosses,' ran one of Mexico's most powerful cartels. The operation follows a near-miss on December 11 when he escaped a Christmas party raid. Marine Melquisedec Angulo Córdova is killed; cartel gunmen later assassinate his family in retaliation.
