The owners of the California dive boat where 34 people died in a fire have filed a lawsuit to avoid liability in the case. Truth Aquatics Inc., which owned the Conception, filed suit Thursday in U.S. District Court under a pre-Civil War provision of maritime law that allows it to limit its liability. Investigators say the crew of the dive ship that sank off the Southern California coast made several attempts to save the 34 people who were trapped by fire and died.
