LOS ANGELES (AP) — The 16-year-old boy who fatally shot two fellow students and wounded three others last week at a Southern California high school used an unregistered, untraceable “ghost gun,” Los Angeles County Sheriff Alex Villanueva said Thursday.Villanueva told media outlets that Nathaniel Berhow’s .45 caliber, 1911-model replica semi-automatic pistol was assembled from gun parts and did not have a serial number.Such weapons are a growing problem for law enforcement around the country because the parts are easy to obtain and the guns take limited expertise to build. In Southern California, federal authorities say one-third of all the firearms seized are ghost guns.California has among the strictest gun laws in the country, but they are based on traditional firearms that are made by manufacturers and labeled so ownership can be traced.RELATED: Santa Clarita high school shooting: 2 killed, 3 hurt; suspected shooter in 'grave' condition"Congress and state legislatures enact all these crimes about gun registration but now the gun industry is creating a way to just bypass the entire thing by creating a mechanism to manufacture weapons yourself," Villanueva said.It’s legal to purchase gun kits and assemble them at home. That method allows the purchaser, sometimes a minor or other person prohibited from owning firearms, to avoid background checks required to purchase ready-made guns from licensed dealers.Thomas Groneman, a detective sergeant with the Suffolk County Police Department in New York, said his agency built their own Glock-replica handgun from parts they ordered online as an experiment earlier this year.“It was ridiculously easy to do it,” he said. “It’s scary because anybody — convicted felons, people with psychological issues — can order it online.”RELATED: 'I'm scared': Students relive escape from Saugus High School shootingIn 2017, a Northern California gunman built his own rifles — despite a court order prohibiting him from having guns — and killed his wife and four others in a rampage.While hobbyists have long been able to use spare parts to create a firearm, modern technology has made it far easier to build a deadly weapon.Adam Winkler, a gun policy expert and professor at the University of California, Los Angeles, said that means more criminals will use them and it will be more difficult for police to solve crimes.“Anytime you can trace a gun, you have a little bit more information,” he said. “How did this gun get here? Who sold it, who was the gunmaker, who was the first person they sold it to and what happened?”Police don’t yet know where and when Berhow got the handgun he used to shoot students at Saugus High School in the Los Angeles suburb of Santa Clarita. As the school day was starting on Nov. 14, he pulled the gun from his backpack in an open-air quad and in 16 seconds shot five students at random, police said.RELATED: Santa Clarita school shooting victim named; Suspected gunman diesBerhow counted his rounds, saving the last bullet for himself, investigators said. He died from a head wound the next day.Anne Muehlberger, 15, and Dominic Blackwell, 14, were killed. The other three students were hospitalized and the last of them went home earlier this week.Berhow’s father was an avid hunter who died two years ago. He had six registered guns, but officials found several other unregistered firearms in the family home after the shooting and are working to determine their history.The sheriff said Berhow’s motive remains a mystery, even after investigators searched his home and interviewed 45 people. Berhow’s mother had no idea of her son’s plans, Villanueva said.Authorities said Berhow had shown no signs of violence and didn’t appear to be linked to any ideology or terrorist group. He ran cross country, was a Boy Scout and had a girlfriend.The sheriff’s department is working with federal authorities to unlock Berhow’s cellphone, Villanueva said. 3943

Look up this week to get a glimpse of Mars, it’s making a “close approach” of Earth right now.On October 13, the Earth is directly in the middle of the sun and Mars. Mars is traveling close to the earth right now, as it does every two years according to its orbit around the sun.Mars will be visible from dusk until dawn in the southern sky. Being “close” is relative, at its closest, Mars will still be 33.9 million miles away, according to NASA. Earth and Mars have elliptical, or egg-shaped, paths around the sun; meaning the distance between the two planets widens and narrows as they orbit.However, even being millions of miles away, the “close approach,” as NASA calls it, will allow an opportunity to see Mars without a telescope. Mars was at its brightest on October 6, and is slowly getting farther away.Mars will appear very bright in the sky during this time as it’s close to earth. NASA says it is more like the size of a star than the moon, a very bright star.If clouds or other distractions block the view of Mars this week, there will be another chance to see the red planet in December 2022. At that time, Mars will get within 38 million miles of earth. 1177

LOS ANGELES (AP) -- California's overwhelmed hospitals are setting up makeshift extra beds for coronavirus patients, and a handful of facilities in hard-hit Los Angeles County are drawing up emergency plans in case they have to limit how many people receive life-saving care.The number of people hospitalized across California with confirmed COVID-19 infections is more than double the state's previous peak, reached in July.A state model forecasts the total could hit 75,000 patients by mid-January.Dr. Christina Ghaly, Los Angeles County's health services director, said plans for rationing care are not in place yet, but they need to be established because "the worst is yet to come." 695

LOS ANGELES (AP) — The western Joshua tree needs protection under the California Endangered Species Act because of threats from climate change and habitat destruction, the Center for Biological Diversity said in a petition Tuesday to the state's Fish and Game Commission.The petition comes amid rising concern about the future of the crazy-limbed trees with spikey leaves that have come to symbolize the Mojave Desert and draw throngs to Joshua Tree National Park."The state has to step up for these trees," center conservation director Brendan Cummings said in a statement.The petition asks that western Joshua trees be given "threatened" status under the act.The request states that the trees meet the definition of a plant that "is likely to become an endangered species in the foreseeable future in the absence of the special protection and management efforts."Researchers have found that Joshua trees are dying off due to hotter and drier conditions, and fewer young trees are surviving, according to the center, a nonprofit conservation organization based in Tucson, Arizona.The trees are migrating to higher elevations where there are cooler and more moist conditions, but they face destruction by fire due to invasive, non-native grasses in those locations.Joshua trees also face challenges due to urban sprawl in the desert as well degradation of habitat for energy projects, powerlines, pipelines and off-road-vehicle use.The western Joshua tree's habitat includes Joshua Tree National Park and stretches to the west along the north slopes of the San Bernardino and San Gabriel mountain ranges into the Antelope Valley, northward along the eastern flank of the southern Sierra Nevada and eastward toward the edge of Death Valley National Park and into Nevada.The eastern Joshua tree — a distinctly different plant — lives in the Mojave National Preserve and eastward into Nevada, Arizona and Utah.The Center for Biological Diversity said that under the California Endangered Species Act, the state Department of Fish and Wildlife has three months to make a recommendation to the Fish and Game Commission, which would then vote on the petition next year. 2171
