Authorities seek cause of California boat fire

U.S. authorities are investigating potential ignition sources of a deadly fire on a scuba diving boat, including electronics aboard the vessel.

National Transportation Safety Board member Jennifer Homendy says investigators know photography equipment, batteries and other electronics were stored and plugged in on the Conception.

She said officials aren’t ruling out any possibilities as they probe what caused the blaze.

Homendy also said she inspected a vessel similar to the Conception and was concerned about the accessibility of its escape hatch.

The Conception had been in full compliance with Coast Guard regulations.

Authorities say 34 people were likely trapped below decks of the Conception. Divers have recovered all but one body.

Five crew members, including the captain, managed to escape.
