UPDATE: Wildfires Kill One; Still Burning

Authorities reported Monday that a pair of Los Angeles area wildfires that are being driven by strong Santa Ana winds have killed a man, while destroying several dozen mobile homes.

The fires continued to threaten neighborhood outside of downtown Los Angeles, along with forcing evacuations.

Firefighters continued to battle a 3,700-acre blaze in the San Fernando Valley's northeastern corner as a new blaze formed at midmorning a few miles to the west in mountains above the Porter Ranch area.

The fatality reportedly occurred at the first fire. The victim was a man who appeared to be a transient living in a makeshift shelter, according to authorities.

A number of "suspicious" fires involving a few acres were reported Monday at various areas in the county, some near the Antelope Valley (14) Freeway, according to authorities. Officials urged people to call authorities if they witness anything suspicious.
