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

LOS ANGELES, Calif. – A judge has denied a request from Britney Spears to end her father’s conservatorship over her estate, though the pop star did score small victories in the case.Los Angeles Superior Court Judge Brenda Penny declined to suspend James “Jamie” Spears from his central role in the court conservatorship, but said she would consider future petitions for his suspension or outright removal, The Associated Press reports.Spears’ attorney, Samuel D. Ingham III, said he plans to file those petitions.The judge also approved a request from Spears for a corporate fiduciary, the Bessemer Trust, to now serve as co-conservator with her father.During Tuesday’s contentious court hearing, Ingham said his client fears her father and won’t resume her career as long as he has power over it. The 38-year-old singer has been on a hiatus since early 2019.A lawyer for Spears’ father argued during the hearing that he has been an excellent conservator and has taken his daughter from being in debt to being worth more than million.Spears’ conservatorship has been in place since 2008, when the star experienced mental health issues and her public meltdowns were widely reported on. Since then, however, she has made a comeback in her career and held a residency in Las Vegas.Legal experts told the Los Angeles Times that it’s unusual for someone as young and productive as Spears to be in this type of situation for so long and that conservatorships like these are usually used to protect the old, infirm or mentally disabled.The L.A. Times reports that another hearing in the case is set for Dec. 16. 1616

LOS ANGELES (AP) — Californians mostly heeded warnings to stay away from beaches and other public spaces during the long weekend. State officials urged social distancing amid a spike in coronavirus infections and hospitalizations. Many communities canceled July 4 fireworks shows and other annual festivities — changes that appeared to successfully keep crowds at bay. However big waves at Southern California beaches proved irresistible to some surfers. California reported 6,500 additional confirmed cases of the virus on Saturday. The actual number of infections is thought to be far higher because many people have not been tested, and studies suggest people can be infected with the virus without feeling sick. 723

LONDON (AP) — The World Health Organization is acknowledging the possibility that COVID-19 might be spread in the air under certain conditions.This comes after an open letter from more than 200 scientists published this week urging the agency to do so.WHO has long dismissed the possibility that the coronavirus is airborne except for certain risky medical procedures, such as when patients are first put on breathing machines.But it noted on Thursday that studies evaluating COVID-19 outbreaks in restaurants, choir practices and fitness classes suggested the virus might have been spread in the air. 609

LOS ANGELES (CNS) - Downward trends in coronavirus cases and testing-positivity rates could allow Los Angeles County to move into the next tier of the state's economic-reopening matrix by sometime in October, according to the county's public health director, but pending Labor Day numbers could potentially thwart that move.The county is in the most restrictive, or "purple," level of the state's four-tier virus-tracking roadmap. The county already has a low enough seven-day average testing positivity rate -- around 3.2% -- to move to a less-restrictive tier, but average new case numbers are still too high, currently averaging 8.1 cases per 100,000 residents. The state threshold for advancing to the "red" tier is seven cases per 100,000.However, Public health director Barbara Ferrer said Wednesday numbers in all categories have been trending downward over the past six weeks following a spike seen after the Fourth of July holiday weekend."If we don't see a surge in cases and hospitalizations associated with activities over Labor Day and we continue to reduce our rate of community transmission over the weeks ahead, we could enter tier 2, which is a less restrictive tier, sometime in October," Ferrer said.Health officials have said repeatedly they will not consider any more business reopenings in the county until at least late September, after determining if virus cases and hospitalizations increase following the Labor Day holiday weekend -- the way they did after Memorial Day and the Fourth of July.If the county gets its average new case numbers below seven per 100,000 residents, and maintains that level for two weeks, the county will be able to move into the state's "red" tier. That would allow more businesses to reopen, including potentially movie theaters and gyms, as well as school campuses for in-person learning.Ferrer said the county is now seeing its lowest average testing- positivity rate of the pandemic."Last week, we saw the lowest positivity rate to date, at around 3.4%," she said. "This means that almost 97% of the tests that people took for COVID-19 ended up being negative. Just a month ago, in mid-August, this rate was around 5%. So we're happy to see the progress that we've made and we're very much hoping that this number continues to decrease."She again warned, however, that the impact of the Labor Day holiday weekend has yet to be borne out in case numbers, since the virus has a 14-day incubation period. She also said upcoming fall and winter holidays, including the start of Rosh Hashanah this weekend, could lead to setbacks if people become lax about social distancing and other preventive measures."The autumn and winter months are filled with special times that we all are looking forward to," she said. "There's many secular and religious holidays that we usually celebrate by spending time with our friends and extended family members. And the pandemic has been difficult and frustrating in many ways, including placing limits on how we can celebrate safely. I do encourage all of us to think now about how we might want to modify our plans so we can share the joy of the holidays while reducing the risk of transmitting a dangerous and sometimes deadly virus."She and the county's health services director, Dr. Christina Ghaly, urged people to get a flu shot, noting that as flu season arrives, people who contract both influenza and COVID-19 may be susceptible to severe illness.The county on Wednesday reported 31 coronavirus-related deaths, although one of those fatalities was actually announced Tuesday by health officials in Long Beach. Long Beach announced two additional deaths Wednesday afternoon. The total number of fatalities in the county stood at 6,305 as of Wednesday.The county also announced 1,148 newly confirmed cases, while Long Beach added 40 cases and Pasadena reported six, lifting the cumulative total since the start of the pandemic to 256,194.There were 804 people hospitalized due to COVID-19 in the county, up slightly from Tuesday. Ghaly noted that the sharp downward trend seen in hospitalizations over the past month appears to have slowed or leveled off. But hospitalization numbers till remained at dramatically lower levels than they were a month ago.Ghaly said overall testing numbers over the past week were down, thanks in part due to closures of some testing centers due to poor air quality caused by the region's wildfires. She said some testing sites have two-thirds of their appointment slots available, so she encouraged anyone with symptoms of the coronavirus or who thinks they may have been exposed to get tested. 4630
