A couple was traveling in their truck at kilometer 146 of the free highway Zapotlanejo-Guadalajara, in the state of Jalisco, when three elements of the National Guard (GN) began to chase the vehicle because they were driving at high speed and their vehicle did not have license plates.

After the truck did not heed the order to stop that the uniformed officers gave them, they fired their weapons against the vehicle. A minor, two months pregnant was hit and killed by the shots fired by the National Guard while performing the duties of traffic police.
