MEXICO CITY - Mexican police in the northern city of Torreon found the severed heads of five people killed in a suspected outbreak of drug gang violence.
Officials were still searching for the bodies. The heads were found in black bags in various parts of the city late on Friday, a spokesman for the ministry of public security in the state of Coahuila said on Saturday.
Threatening messages were left with the severed heads - a common feature of killings by drug cartels in Mexico - that suggested the slayings were the result of feuding between local gangs, the spokesman said.
More than 46,000 people have died in drug-related violence since President Felipe Calderon launched an army-led crackdown on the cartels after taking office five years ago.
