Catalina fire: The search for a cause

One single-family home was destroyed along with six industrial and commercial buildings, said Steven Hofs, the Avalon fire chief.

He said there is still no known cause for the fire. Some contractors were working on an antenna near where the blaze started, and investigators said they were looking into whether they might have accidentally -- and perhaps unknowingly -- sparked it.
