A gruesome discovery near Cancun. Six bodies have been found in a cave, three of them with their hearts removed.
Mexican authorities are trying to determine the identity of the four men and two women. The letter 'z' carved on their abdomens may be a possible reference to the Zeta drug gang. More than 22,700 people have died since Mexico's president sent soldiers and federal police to battle the drug cartels at the border.
In a separate incident in the southwestern part of the country, armed men in two cars barged into a girl's fifteenth birthday celebration and sparked a gunfight. Three people are dead and three wounded.
