Cal Fire released new details Tuesday in the death of a San Diego firefighter who died while battling the Thomas Fire last month in Ventura County. The report says engineer Cory Iverson died on a hillside above Fillmore after being surrounded by spot fires in windy conditions. On December 14, Iverson’s strike team was in an area above an avocado orchard when a mayday call went out around 9:30 a.m. A Cal Fire captain was on a nearby overlook supervising the operation, according to the Green Sheet report obtained by CBS News 8 under California Public Records Act. The report outlines the sequence of events that led to Iverson's death and includes photographs of the area where Iverson lost his life.
