Lawsuit alleges Genasys emergency alert system failed to warn resident during Eaton Fire
A wrongful death lawsuit filed in November 2025 alleges that Genasys' emergency alert software failed to warn residents in parts of Altadena, including a 54-year-old woman who died in the January 2025 Eaton Fire. The suit claims the system's predefined evacuation zones, or "polygons," prevented residents east of Lake Avenue from receiving timely evacuation orders despite the resident following available evacuation guidance.
What happened
On January 7, 2025, the Eaton Fire ignited near Eaton Canyon around 6:30 p.m. in Altadena, California, with extreme red flag conditions and hurricane-force winds spreading red-hot embers for miles and destroying thousands of homes.
The lawsuit alleges that Genasys' emergency alert software, which Los Angeles County uses for emergency communications, failed to send evacuation warnings to residents east of Lake Avenue due to the system's predefined evacuation zones, or 'polygons.'
The complaint also names Southern California Edison, alleging the utility's equipment ignited the fire, though no official cause has been determined.
Reported impact
Stacey Darden, a 54-year-old Altadena resident, died in the Eaton Fire on January 7, 2025.
Nineteen people in Altadena died in the fire. The lawsuit's family representative stated the deceased 'was studiously following the evacuation orders the night of the Eaton Fire' but did not receive timely warnings from the alert system.
Index analysis
The lawsuit claims the system's predefined evacuation zones failed to extend alerts to a significant portion of the community, preventing residents from receiving timely notification to evacuate.
Governance controls
Los Angeles County previously suspended use of Genasys' alert system following the fire.
Genasys denied wrongdoing and stated it would 'vigorously defend itself against these allegations.'
