In a Sept. 12, 2019, file photo, the burned hull of the dive boat Conception is brought to the surface by a salvage team off Santa Cruz Island, Calif. Deaths from California fires on the scuba diving boat and at the so-called Ghost Ship warehouse have brought a search for blame aimed at finding whether someone was negligent. Getting criminal charges to stick in the 2016 fire at the Ghost Ship warehouse has proven difficult and could provide lessons as investigators decide whether a crime occurred aboard the Conception scuba diving boat that burned this month.
