Southern California Edison said video evidence had led it to look more broadly at whether its equipment might have been the cause of the deadly blaze.

Edison International’s utility said it is looking at whether a decommissioned power line started the Eaton wildfire as part of a probe into the cause of the blaze that razed more than 9,000 structures near Los Angeles.

A California utility said Thursday that its equipment likely sparked a wildfire in Los Angeles that broke out the same day as two massive blazes in the area killed at least 29 people and destroyed thousands of homes.

Southern California Edison officials conceded in a regulatory filing that its equipment “may be associated with” the ignition of the Hurst Fire, which burned nearly 800 acres in Sylmar.
