SAN DIEGO -- Firefighters in California are finally getting the upper hand on the wildfires that have burned dozens of homes. As the fire gets under control, the investigation begins.

San Diego was plagued by dozens of wildfires in a week's time causing speculation that arson is on the rise.

Police have three men in custody after people reported seeing them set small fires.

More than 25,000 acres in San Diego County burned, reducing 40 homes to rubble and causing wide-spread evacuations.

California's Governor Jerry Brown cites climate change as a factor in the fires.

The last three years have been the driest in recorded history in that state.
