The fire broke out on the afternoon of Thursday, Oct. 10 in the area of Sandalwood Drive and Calimesa Boulevard, east of Mesa View Middle School.

Investigators believe it was sparked by a trash truck which attempted to dump a load of burning garbage into the vegetation. CBS2 obtained cell phone video of the burning truck just prior to when it dumped its load.  Shawn Melvin’s 8-year-old son shot footage of the truck on fire as they followed behind in their own car.

“I pulled up to him (the driver) and said, ‘You cannot stay here,'” Melvin told CBS2 Friday. “‘With the wind, and the field right there, you’re going to catch everything on fire.’ He kind of looked me like, ‘What do you want me to do?’”
