I am pretty sure this is a Navy plane that was converted to a slurry bomber. It crashed on June 15, 1961 killing the pilot, Chuck Cochrane while fighting the Roberts Fire. He was having engine problems and crashed before making it back to the airport. The majority of the aircraft was removed in the late 70's. You can see on your one photo of the blue piece of metal with the painted "V" and a small white painted spot to the right of the "V" would have been a "Y" for Navy. You can also see where the metal has a smooth cut not the jagged fracture breaks that would have occurred during the crash sequence as seen in the other debris photos . Not sure why the salvage crew did not remove those pieces as well. Somewhere I have a photo of plane shortly after the crash.
