Firefighters still don’t know why or how the fire began, only that it sparked at the roadside and spread so quickly that the three engines that arrived could not get a handle on it.

The wind was blowing the fire so quickly, many of the trailers were already engulfed when firefighters arrived.

“On top of that, we also had other area agencies that were already fighting fires and on other emergency calls that limited our resources,” said Assistant Chief Jessie Rosewall of River Delta Fire.

Larry Rodriguez could only watch as the trailer he moved into a few months ago went up in flames. “It is kind of an empty sensation. I mean, there is nothing you can do about it,” Rodriguez told KPIX 5.
