The third occupant who shot the video is in custody. The state prosecutor said the shooting is being reviewed by the state police’s Internal Affairs unit. He added he did not want to “re-victimize” the young men but questioned the aggressive driving in front of the officer.

That is part of the investigation,” Salas said. “If this happened in another country, in the United States, if you move forth at that speed […] the police will react,” he said. “It is a regrettable case and the instruction we have from the attorney general is that we follow the law without question.” Salas said the officer was accompanying a state prosecutor serving a warrant in the neighborhood. "In many of the warrants, the citations these prosecutors serve, they are accompanied by municipal police, state agencies or the National Guard. We live a complicated environment in this city and the prosecutors face many risks," he said.
