A brush fire that exploded in Orange County Monday amid peak fire conditions left two firefighters critically injured while thousands evacuated the Irvine area.
The Easy and Maria fires, which broke out in Ventura County in October 2019, were both caused by electrical equipment failures, authorities announced Thursday. Geoff Petrulis reports.
