Video from a gas station security camera shows what a new filing in a lawsuit alleges is the start of this month’s deadly Eaton Fire in the Los Angeles area – electrical sparking at a utility transmission tower in the hilly Eaton Canyon area near the Altadena community.

A video shows arcing at a Southern California Edison tower, then a fire at the tower's base, suggesting the Eaton fire may have been caused by electrical equipment.

While investigators are still working to determine the official cause, several attorneys allege this real-time video is the strongest evidence yet, that suggests the Eaton Fire started at a Southern California Edison transmission tower.
