MEXICO CITY – Fourteen federal police officers will be charged with attempted homicide for the Aug. 24 attack on a U.S. Embassy vehicle that left two American government security experts wounded, the Mexican Attorney General’s Office said Friday.

A dozen cops were detained immediately after the incident and two more were taken into custody last month.

It was only the embassy vehicle’s armor plating that saved the lives of the two U.S. officials and the Mexican marine accompanying them, the AG’s office said.

Investigators found 152 bullet holes in the vehicle.

Ballistics evidence proved the bullets came from the service weapons of the 14 accused officers, who were dressed in plainclothes and traveling in their personal vehicles at the time of the attack, the AG’s office said.

Several of the accused cops were not involved in the shooting, but did take part in an attempted cover-up, according to prosecutors.

The assault took place on a road in the central Mexican state of Morelos.

The U.S. agents left Mexico shortly after the attack without giving statements to investigators.

The AG’s office said Friday that the U.S. Embassy cooperated with the probe. EFE
