On May 23 Casey James Fury had anxiety and wanted to get home early from his Navy job on a Navy attack sub, so he “”…grabbed his cigarettes and a lighter, walked up to a bunk room and set fire to some rags on the top bunk."" The Navy originally said the fire started when an industrial vacuum cleaner sucked up a heat source that ignited debris inside."
The damage is estimated at $400 million.
