Just what sparked the deadly and devastating Palisades Fire? Some residents believe the fire may have started nearly a week earlier and then reignited.

In the hills above Pacific Palisades, there is crime scene tape and scattered debris, clues to what may have caused the initial fire that eventually raged through thousands of structures.

Photos show both fires broke out in the same area and experts said it’s plausible the earlier fire could have led to another fire six days later.
