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

LONDON (AP) — British actress Barbara Windsor, whose seven-decade career ranged from cheeky film comedies to the soap opera “EastEnders,” has died. She was 83.Husband Scott Mitchell said Windsor died at a care home in London on Thursday from Alzheimer’s disease. She had been diagnosed with the form of dementia in 2014.Born in London in 1937, Windsor was best known as a star of the bawdy “Carry On” comedies in the 1960s and 70s, and as matriarch Peggy Mitchell in the soap opera “EastEnders” between 1994 and 2016.Windsor was made a dame, the female equivalent of a knight, by the queen in 2016 for services to entertainment and for her work raising awareness about dementia. 686

LOS ANGELES (AP) — The climbers were closing in on the top of California's second-highest peak when they came upon the grisly discovery of what looked like a bone buried in a boulder field.Closer inspection revealed a fractured human skull. Tyler Hofer and his climbing partner moved rocks aside and discovered an entire skeleton. It appeared to have been there long enough that all that remained were bones, a pair of leather shoes and a belt.The discovery a week ago beneath Mount Williamson unearthed a mystery: Who was the unfortunate hiker? How did he or she die? Was the person alone? Were they ever reported injured, dead or missing?The Inyo County Sheriff's Department doesn't have any of those answers yet. But it retrieved the remains Wednesday in the hopes of finding the identity and what happened. There's no evidence to suggest foul play, spokeswoman Carma Roper said."This is a huge mystery for us," Roper said.The body was discovered Oct. 7 near a lake in the remote rock-filled bowl between the towering peaks of Mount Tyndall and Williamson, which rises to 14,374 feet (4,381 meters). The behemoth of a mountain looms large over the Owens Valley below and overshadows the former World War II Japanese internment camp at Manzanar.Hofer and a friend had gone slightly off the trail-less route as they picked their way through boulders when they stumbled upon the shocking find."The average person who was hiking to Williamson wouldn't have gone the route we went because we were a little bit lost, a little bit off course," Hofer told The Associated Press. "So it made sense that nobody would have stumbled across the body."Hofer phoned from the summit to report the finding and went to the sheriff's department the next day after hiking out to speak with investigators.Sgt. Nate Derr, who coordinates the county's search and rescue team, said bodies found in the mountains are typically connected with someone they know who has gone missing. The opposite is rarer: finding the remains of someone who appears to not have gone missing or been reported as missing.They plan to use DNA to try to identify the remains.Because the body was so decomposed, investigators believe it's possibly been there for decades.Authorities have ruled out that it's 1st Lt. Matthew Kraft, a Marine from Connecticut who vanished in February during a nearly 200-mile (320-kilometer) ski trek through the Sierra. Derr also doubts it's Matthew Greene, a Pennsylvania climber last seen in the Mammoth Lakes area — nearly 70 miles (112 kilometers) north — in 2013.Investigators have gone back through decades of reports of people missing in the Inyo National Forest and come up empty, Derr said. Neighboring Sequoia and Kings Canyon national parks also don't have reports of anyone missing in that area, he said.Bodies of those who go missing in the mountains are discovered from time to time, but it can take years and even decades.It took five years — after an exhaustive search was called off — before a trail worker discovered the body of Randy Morgenson, a Kings Canyon National Park ranger who vanished in 1996. A World War II airman whose plane had crashed near Mount Mendel on a training flight in 1942 wasn't found until 2005 when a receding glacier gave up his body.Hofer, a church pastor in San Diego, said it appeared to him the body was intentionally buried. The skeleton was laid out on its back with the arms crossed over the chest."It wasn't in a position of distress or curled up," Hofer said. "It was definitely a burial because it was very strategically covered with rocks."The death could have occurred in the days before helicopters were used to fly out bodies, Derr said. It's possible that the person perished on the mountain and was buried by a climbing partner."I can't say whether it's intentional or not, but it's not an area that would be prone to rockfall," Derr said.Although the mountain is the state's second-highest, it's not summited as frequently as other high Sierra peaks because it is a forbidding approach. The elevation gain from the trailhead in the high desert to the summit is the greatest of any peak in California.It can take more than a day to hike over Shepherd Pass and then the trail ends, and climbers have to make a tedious scramble over rock fields and sand across Williamson Bowl — where the body was found — before climbing the final 2,000 feet (600 meters) up a chute that includes moments of breathtaking exposure while picking their way up a rock face.Hofer posted about his finding on a mountaineers forum on Facebook that sparked speculation about the death, in part because Hofer described the shoes as the type worn by rock climbers.That seemed unusual because the area is not well known for rock climbing. And, because most climbers work in pairs, it raised questions about what had happened to any partner or whether the death had been reported.Derr said he did not think they were climbing shoes but couldn't rule that possibility out.Hofer said he summited the peak after his discovery and wasn't haunted by the image.He was more excited he might be able to let someone know about a lost loved one as he ran through the various scenarios of how the body got there."A couple of times we said out loud, 'This is really crazy that we found a body there that no one knew about,'" he said. 5347

LOS ANGELES (AP) -- California health officials have released guidelines for elementary schools to seek waivers allowing them to offer classroom instruction in the midst of the coronavirus pandemic.Officials on Monday said some public and private schools in 38 counties on a state watch list, including San Diego County, can seek waivers from local health officials if they have plans for keeping students and staff safe and meet certain criteria.But the state says school reopenings can't be considered in counties with the highest rates of COVID-19 infection. That includes Los Angeles, which has the nation's second-largest school district.San Diego County has the fifth-highest number of virus cases in the state as of Aug. 3.The waiver only applies to schools with grades TK-6.Click here to learn more about the California Department of Public Health’s waiver process 880

LOS ANGELES (AP) — California Sen. Dianne Feinstein has endorsed Joe Biden for president, lining up with a fellow centrist Democrat and onetime Senate colleague and snubbing her home-state counterpart, Sen. Kamala Harris.In a statement Tuesday, Feinstein says she has worked closely with the former vice president and Delaware senator and has "seen firsthand his legislative ability, his statesmanship and most importantly his moral fortitude."The endorsement was not unexpected — Feinstein earlier indicated she favored Biden and recently held a fundraiser for him at her San Francisco home. The announcement comes at a time when Harris has been fading in polls and is struggling to regain her earlier momentum in the 2020 contest.Feinstein says Biden "will continue the fight to restore the soul of the nation from the Oval Office." 842
