LOS ANGELES (AP) -- The prestigious University of California system has reached a proposed million settlement with seven women who accused a former gynecologist of sexual abuse.As part of the class-action lawsuit, more than 6,600 patients of Dr. James Heaps could receive part of the settlement -- even if they have not formally accused the former University of California, Los Angeles, gynecologist of abuse.A federal judge must approve the proposed agreement filed Monday. The tentative settlement includes several mandated reforms at UCLA.Heaps has pleaded not guilty in a separate criminal case and denies wrongdoing.Heaps' attorney didn't immediately return an Associated Press request for comment. 715

LOS ANGELES (CNS) - Newly published research indicates there's an almost one-in-four chance the mountain lions living in the Santa Monica and Santa Ana mountains could become extinct in those areas within 50 years as a result of urban encroachment, inbreeding, vehicle strikes, rat poison and wildfire, it was reported today.In the face of such a dire prognosis, what biologists call an extinction vortex, conservationists are considering a desperate and controversial remedy: capturing pumas in one part of the Santa Anas and trucking them across the 15 Freeway so that they can breed with isolated mates on the other side of traffic."Wildlife managers never want to be a shuttle service for wild animals,'' said Justin Dellinger, senior environmental scientist with the Wildlife Investigations Laboratory at the California Department of Fish and Wildlife, the Los Angeles Times reported. But translocation has potential merit in the short term; after all it helped bring the critically endangered Florida panther back from the brink.Mountain lions are not endangered in California, but groups living in the Santa Monica and Santa Ana ranges now find themselves in genetic peril. Separated by freeways and lethal traffic, they are unable to range freely and are growing increasingly inbred, researchers say.In the Santa Monica Mountains, the 101 Freeway exists as a near impenetrable barrier to gene flow for a group of 10 mountain lions; in the Santa Ana Mountains, the 15 Freeway limits the movement of a family of 20 cougars.Sometimes, the animals manage to cross freeways without getting hit. At least seven cougars have crossed the 15 Freeway near Temecula in the last 15 years, and one sired 11 kittens. The fact that only one managed to reproduce, however, shows how difficult it is to diversify the gene pool in the lions still prowling the range.A population viability study published in the journal Ecological Applications predicts extinction probabilities of 16 to 28 percent over the next 50 years for these lions, which have the lowest genetic diversity documented for the specie aside from the critically endangered Florida panther.Study authors note also that wildfire and disease could result in "catastrophic mortality'' and further hasten the animals' disappearance.However, extinction probabilities were significantly reduced when computer models simulated the influence of two immigrant lions per year in areas blocked by development and freeways, according to a team of researchers that included Winston Vickers, an associate veterinarian at the UC Davis Karen C. Drayer Wildlife Health Center, and Seth Riley, an ecologist with the Santa Monica Mountains National Recreation Area, The Times reported. 2731

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 (AP) — The New York and Los Angeles police departments are poking some fun at their perceived rivalry and wading into a hotly contested debate: Is "Die Hard" a Christmas movie?It began when NYPD tweeted Monday that they'd been working with LAPD "to protect Christmas since Hans Gruber's 1988 attack on Nakatomi Plaza" with the hashtag, #YesItsAChristmasMovie.The debate over whether the Bruce Willis blockbuster is a Christmas movie has emerged in recent years. RELATED: 'Die Hard' trailer recut to look more like a Christmas filmSet on Christmas Eve, the movie follows NYPD Detective John McClane as he singlehandedly stops a group of terrorists led by Gruber (Alan Rickman) in Los Angeles.On this Christmas Eve, we’d like to acknowledge our partners at @LAPDHQ who have been working with us to protect Christmas since Hans Gruber’s 1988 attack on Nakatomi Plaza. #DetectiveJohnMclean #YesItsAChristmasMovie pic.twitter.com/qOEgD1Lqt3— NYPD NEWS (@NYPDnews) December 24, 2018 998
