The investigation is critical for not only understanding what happened, but for ensuring it never happens again, said an attorney for 300 Altadena residents.

As the Eaton fire spread, many areas were notified of evacuation warnings and orders well in advance. In the heart of Altadena, where all 17 reported deaths occurred, evacuation orders came hours after fire did.

All of the 17 deaths confirmed in the Eaton Fire occurred in an area where an evacuation order was delayed for hours after the blaze erupted, according to a Los Angeles Times report.

Eaton Fire initially started 6:18 p.m. Jan. 7 in Los Angeles County. Since its discovery two weeks ago, it has burned 14,021 acres. A fire crew of 2,375 has been working on site and, as of Tuesday noon, they managed to contain 89% of the fire. However, investigations into the cause are ongoing.

Improving weather conditions continue to aid in the increased containment of both the Eaton and Palisades fires, with some evacuations lifted in the Palisades Fire area.
