Over 40 bodies found in Mexico mass graves in Jalisco

At least twenty two (22) graves have been found in the Mexican state of Jalisco, overall containing more than 40 dead bodies, Attorney General's Office said.
According to federal authorities, the said 40+ bodies are still unidentified but initial investigation revealed wounds from gun shots, including signs of torture.

Mexican Attorney General Jesus Murillo Karam told the media on Monday:

We started the investigation when two police officers disappeared

We found that those responsible for the disappearances of these police officers were municipal police, practically all of them municipal police officers.

We detained them, and from that investigation we found a place where the federal agents might have been buried

This is some kind of a summary execution of the same kind - police officers executing fellows in the same uniform.
