Cause of deadly US boat fire still a mystery

LOS ANGELES (AP) — United States (US) investigators completed a two-week examination of the charred wreckage of a scuba diving boat and could not determine what ignited the fire that killed 34 people off the Southern California coast, a law enforcement official said on Friday.

Specially trained teams from the FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives completed their work there without finding the cause, but the investigation will continue, said the official, who was not authorised to release the information publicly and spoke to The Associated Press on condition of anonymity.
