The owner of a diving boat where 34 people died in a fire is halting operations.

Truth Aquatics says none of its other boats will be used anytime soon. The Santa Barbara company says it wants to focus on recommendations from the federal investigations. So far, experts have not been able to determine what started the Labor Day disaster. Officials say the crew was sleeping as the flames ripped through the boat – an apparent violation of Coast Guard rules. 33 passengers and one crew member died. Five crew members survived by jumping off the Conception as it burned near the Channel Islands. A federal criminal investigation continues.
