SAN DIEGO, Oct. 25 (UPI) -- The wildfire evacuation center at San Diego's Qualcomm Stadium will be closed Friday, as the last of the city's burned-out neighborhoods was reopened.

The San Diego Union-Tribune said late Thursday only a few hundred people remained camped at the stadium.

The death toll from the Southern California wildfires rose Thursday when four bodies were found in a burned-out canyon.

A Border Patrol agent saw one body in the canyon east of Potrero, the Union-Tribune reported. When he got closer, he spotted three more. Three of the dead were men and one a woman.

Three earlier deaths have been blamed directly on the fires and several more deaths were related to the blazes.

At least one of the fires has been blamed on arson. Investigators in Orange County said the Santiago fire near Irvine had two separate points of origin.

The wildfires forced roughly 500,000 evacuations statewide and destroyed around 1,600 homes.
