Officials late Wednesday confirmed a second death in the devastating Valley Fire burning in Lake, Napa and Sonoma counties.

The fire was at 70,200 acres Wednesday evening and was 35 percent contained, Cal Fire said.

No other information was immediately available on the second death.

Earlier in the week, the Lake County Sheriff's Office said the fire claimed the life of an elderly woman with a disability who was unable to evacuate from her house.

Family and friends identified her as 72-year-old Barbara McWilliams who had severe multiple sclerosis, making it difficult for her to move around.

The Valley Fire, which possibly started in a shed, was first reported Saturday.
