Los Angeles County officials are calling for an independent investigation to review the emergency alert system used during the recent Eaton and Palisades Fires to warn residents to evacuate.

All 17 people who died in the wind-fueled Eaton Fire in Lost Angeles were in an area where the first evacuation order wasn’t sent until more than nine hours after the fire started.

The Eaton Fire burning near Altadena and Pasadena has claimed at least 17 lives as of Tuesday afternoon, and while firefighters continue to work to contain the blaze, criticism of the evacuation alert system has already started to mount.
