Six bodies were discovered this week in an area of central Mexico typically immune from the gangland violence that has wracked many other areas of the country.

The Attorney General's Office of the central state of Mexico said Wednesday that authorities had identified five of the six bodies, which had been found the day before with bullet wounds inside a vehicle in the city of Nezahualcoyotl.

The five identified victims - four men between the ages of 36 and 40 and a 42-year-old woman - all had addresses in the eastern Mexico City borough of Iztapalapa.

One other male victim has not yet been identified.

The state AG's office said it learned through interviews with family members of the victims that the five had been seen for the last time on July 9 and that at least one of them had a criminal record related to a mugging.

That prosecutor's office, which said it was working with the Mexico City district attorney's office to solve the case, stated in a bulletin that a review of surveillance cameras showed that the vehicle in which the bodies were found had been driven from the capital to the nearby city of Nezahualcoyotl.

Local media on Wednesday attributed the execution-style killings, which are rare occurrences in the Mexican capital and its vicinity, to a battle among criminal gangs for control of drug-trafficking zones.
