LOS ANGELES (AP) — Officials have vowed to find what sparked the inferno aboard the dive boat Conception that killed 34 people in waters off Southern California, but vital evidence may have gone down with the ship or drifted out to sea.The main piece of evidence, the charred remains of the boat, rests on the sea floor in 60 feet (18 meters) of water. Other items that could provide valuable clues could have been carried away by tides or destroyed in the blaze that burned so hot DNA is needed to identify the dead."All of that will be a very large hurdle to overcome," said George Zeitler, a former Coast Guard inspector who runs his own marine investigation firm. "It will definitely make for a complex investigation."Investigators will want to craft a timeline of the ship's final voyage from the moment it pulled away from a Santa Barbara dock early Saturday morning until dispatchers received the frantic mayday call of the breathless captain overwhelmed by smoke, experts said.RELATED: San Diego woman killed in deadly Conception boat fire off Santa BarbaraThey will look at the ship's layout and whether the bunk room below deck was too cramped and had enough exits, review maintenance records and even study photos and videos from people who have been on the boat to look for valuable evidence.As the investigation into the Labor Day tragedy expands on land and sea, federal and local authorities will look not only at determining what went wrong but also seek lessons that could lead to changes in commercial vessel regulations."Our mission here while we're on scene is to determine how this happened, why it happened and what safety improvements are needed to prevent it from ever happening again," said Jennifer Homendy of the National Transportation Safety Board.The fire, investigated with help from the FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives, is being treated as an accident and there's nothing to suggest anything "nefarious," said Santa Barbara County Sheriff Lt. Erik Raney.The Conception, owned by Truth Aquatics, had been chartered for three days by a commercial dive outfit based in Santa Cruz to explore the rugged Channel Islands, sometimes referred to as the Galapagos of North America, about 20 miles (32 kilometers) south of Santa Barbara.The mayday call came at 3:15 a.m. Monday as passengers would have been sleeping while the boat was anchored just off Santa Cruz Island.While initial details were limited, Santa Barbara County Sheriff Bill Brown said fire above deck blocked the one stairway and an emergency exit hatch where 33 passengers and one crew member were sleeping in their bunks. It's not known if any alarm sounded or what the people below deck may have done to try to escape."If an emergency exit is blocked due to fire and prevents one from escaping, it's a horrific situation," said Hendrik Keijer, an investigator with Robson Forensic who has captained cruise ships and operated cargo boats. "Vessels are mazes."The five survivors were all crew members, including the captain. They apparently jumped from the boat's bow, where the stairway led to the sleeping quarters, and swam to the stern, where they escaped in a dinghy and were taken aboard a nearby boat.Attorney James Mercante, a former merchant marine officer who has defended thousands of maritime casualty cases, said it was unusual that only crew members survived, but that is likely because they were above deck.Mercante said he would want to find out what the crew did upon being alerted to fight the fire and for how long before they abandoned ship."Something was ignited that spread a fire rapidly," Mercante said. "It must have spread awfully quickly if nobody but the crew got out."Even with limited physical evidence, fire investigators should be able to pinpoint where the fire began, though finding the cause will be more difficult, Mercante said.The leading causes of boat fires are, specifically, electrical problems and, generally, stupidity, said Walter Godfrey, who has investigated more than 2,000 boat fires in a career spanning a half-century.By all accounts Godfrey has seen, Truth Aquatics had a good reputation and a clean record of service and was not the type of outfit to employ do-it-yourself electrical wiring."I don't think they'd be cutting those kind of corners," Godfrey said. "I would think just off the top of the head this would have to have been something totally accidental and not something ... you would anticipate."Coast Guard records show fire safety violations on the Conception in 2014 and 2016 were quickly fixed. There were no deficiencies found in February or August 2018 inspections.The same problems that lead to house fires every day can also sink ships: kitchen fires, unextinguished cigarette butts and gas leaks.While experts did not want to speculate on a cause, Godfrey said he would want to know more about the built-in barbecue on board and where gasoline was stored for the dinghy. He said electrical fires are most common because a boat — even when docked — is always moving and wires get chafed and exposed. They can arc and spark or ignite gas vapors.A fire on board can rapidly become a terrifying situation with no help nearby."It's very difficult to fight fires without outside help," Keijer said. "You're really on your own in most instances. It's up to the vessel's crew to fight fires. It's not like one can easily escape a vessel. You walk out of a building if a fire occurs on land. That's not as easy on vessels." 5515

LOS ANGELES (CNS) - USC researchers have found the likely order in which COVID-19 symptoms first appear: fever, then cough and muscle pain, followed by nausea, and/or vomiting, and diarrhea, it was announced Thursday.Knowing the order of COVID-19's symptoms may help patients seek care promptly or decide sooner than later to self isolate, according to scientists at the USC Michelson Center for Convergent Bioscience. The information also may help doctors rule out other illnesses, or help doctors plan how to treat patients, and perhaps intervene earlier in the disease.The study, which appears in the journal Frontiers in Public Health, was led by doctoral candidate Joseph Larsen and scientists Peter Kuhn and James Hicks at the USC Michelson Center's Convergent Science Institute in Cancer."This order is especially important to know when we have overlapping cycles of illnesses like the flu that coincide with infections of COVID-19," said Kuhn, a USC professor of medicine, biomedical engineering, and aerospace and mechanical engineering. "Doctors can determine what steps to take to care for the patient, and they may prevent the patient's condition from worsening."Fever and cough are frequently associated with a variety of respiratory illnesses, including influenza, Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome. But the timing and symptoms in the upper and lower gastrointestinal tract set COVID-19 apart."Given that there are now better approaches to treatments for COVID- 19, identifying patients earlier could reduce hospitalization time," Larsen said.To determine COVID symptom chronology, the authors analyzed more than 55,000 confirmed coronavirus cases in China collected from Feb. 16 to Feb. 24 by the World Health Organization. They also studied a dataset of nearly 1,100 cases collected from Dec. 11 through Jan. 29 by the China Medical Treatment Expert Group via the National Health Commission of China.In addition, to compare the order of COVID-19 symptoms to influenza, the researchers examined data from 2,470 cases in North America, Europe and the Southern Hemisphere, which were reported to health authorities from 1994 to 1998."The order of the symptoms matter, " Larsen said. "Knowing that each illness progresses differently means that doctors can identify sooner whether someone likely has COVID-19, or another illness, which can help them make better treatment decisions." 2440

LOS ANGELES (AP) — Authorities say “Glee” star Naya Rivera has been found dead at a Southern California lake. Ventura County sheriff’s officials confirmed at a news conference that the body found floating in Lake Piru earlier Monday was the 33-year-old Rivera. The discovery came five days after Rivera’s 4-year-old son was found asleep and alone on a rented boat. Authorities said the following day they believed Rivera had drowned. She is the third star of the Fox musical-comedy series “Glee” to die in their 30s. Her death was confirmed exactly seven years after co-star Corey Monteith died. 603

LOS ANGELES (CNS) - Workers at Ralphs, Albertsons and Vons/Pavilions throughout Southern California and as far north as Santa Maria ``overwhelmingly'' ratified a new contract with the grocery chains, averting a potentially costly and disruptive strike, union officials announced Thursday. Officials with the United Food and Commercial Workers Local 770, the Los Angeles-area union representing grocery workers, issued a statement saying the deal ``represents the most significant increases in wages and benefits in over 30 years.'' ``This agreement is a first step towards security good, career jobs in the changing grocery industry,'' Kathy Finn, secretary-treasurer of UFCW 770, said in a statement. ``As important as the hundreds of millions of dollars in improvements to members is the way we got to this contract -- by standing together store by store and with our communities to demand recognition of the value we earn these corporations every day.'' Union members cast ballots on the contract proposal Monday and Tuesday. The tentative deal was announced Sunday. The previous contract between the union and the grocery companies expired in March. Grocery workers in June voted to authorize a strike if a contract deal could not be reached -- raising fears of a repeat of the 2003-04 Southland grocery strike that dragged on for 141 days. When the tentative deal was announced Sunday, Ralphs spokesman John Votava said, ``We are pleased to have worked with the union to secure increased wages, continued premium health care coverage, and pension. Our associates are the heart of our company and this agreement is a reflection of their contributions.'' According to the union, the three-year deal includes wage increases of .55 and .65 per hour depending on job classification, with pay retroactive to March. Union officials said the pact also includes more guaranteed work hours for veteran workers, improvements in health care coverage for employees and their families, full pension funding and the start of a movement to close ``the wage gap between job classifications.'' The employees work at 532 stores stretching from Central California to the Mexican border. Albertsons and Vons/Pavilions have 342 stores and 29,000 unionized employees in the region, while Ralphs has 190 stores and 18,000 employees. 2325
