Sara Irene Herrerías said the six include three officials from the National Immigration Institute, two private security guards contracted by the agency and the person accused of starting the fire. Herrerías said five of the six have already been arrested and they will face charges of homicide and causing injuries.
At least 39 migrants died after apparently starting a fire inside a holding cell at the facility Monday night. More than two dozen other migrants were injured.
A video from a security camera inside the Ciudad Juarez facility showed guards walking away when the fire started late Monday inside the cell holding the migrants and not making any attempt to release them. It was not clear whether those guards had keys to the cell doors.
