Bodies could be those of missing San Fernando massacre investigators

Mexican prosecutors say two dead bodies found in the northern state of Tamaulipas appear to be those of a state detective and local police chief who were investigating the massacre of 72 migrants in August.

The officials have been missing since they participated in the initial investigations into the Aug. 23 killings.

The Tamaulipas state prosecutor's office says identification documents found on the bodies matched those of the missing officials.

But the office said Tuesday it was conducting DNA tests to confirm the identities.

If the two officials investigation such a high-profile case were killed, it would be a startling demonstration of drug gangs' power, and their desire to intimidate those who investigate such crimes.
