California ? One person was found dead inside a burned-out house Friday after a wind-fueled wildfire swept through a rural community in the Sierra Nevada foothills, a rare human casualty among the hundreds of blazes that have tormented the state for weeks.

Investigators believe the person died in the fire in the town of Concow, but they will conduct an autopsy on the burned body to confirm the cause of death, said Sgt. Steven Pelton, the county’s deputy coroner-sheriff.

A complex of blazes in Butte County already has destroyed 50 homes in Concow and forced some 10,000 residents of the nearby town of Paradise to flee.

Gov. Arnold Schwarzenegger ordered an additional 2,000 National Guard troops to help firefighting efforts around the state. President Bush planned a visit next week to survey the Golden State’s wildfires, which have burned more than 1,100 square miles and destroyed about 100 homes.
