Only Joaquin "Shorty" Guzman, boss of the Sinaloa Cartel, would represent a bigger prize to the government.By ReutersMexican marines may have killed the leader of the brutal Zetas drug cartel in a gun battle in northern Mexico, in what would be one of the biggest victories yet in the government's six-year war on organized crime.
The Navy said late on Monday there was "strong evidence" Heriberto Lazcano had been killed in a firefight with marines in the northern state of Coahuila on Sunday afternoon.

The Zetas, considered one of the two most powerful drug gangs in Mexico, have perpetrated some of the most sickening acts seen in the country's drug war that has killed about 60,000 people during Calderon's term.
