Relatives of victims of the massacre in Uvalde seek the resignation of the police chief, the superintendent and the school board

The families of the victims of the de Uvalde massacre gave the school board an ultimatum: fire the school's police chief, Pete Arredondo.

This dismissal is not enough, as they also claim that they are seeking the resignation of the superintendent and the entire school board.

CNN's Rosa Flores spoke with Brett Cross, uncle of one of the victims, who has been very close to the investigation and even got a tattoo in honor of his nephew.
