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 (AP) — A judge has blocked a Trump administration rule that would have put up new roadblocks for asylum-seekers convicted of a variety of crimes. It was set to take effect Friday. The federal judge in San Francisco says current federal law already includes plenty of disqualifying crimes such as drug trafficking, money laundering and counterfeiting. A California-based legal service provider sued after the rule was announced last month by the departments of Homeland Security and Justice. The White House didn't immediately comment on the decision. President-elect Joe Biden has said he will end Trump’s “detrimental asylum policies” but hasn't commented on this specific rule. 699

LOS ANGELES (AP) — Lawyers for California Rep. Duncan Hunter want a federal judge to reject an attempt by prosecutors to introduce evidence that the congressman used campaign funds to finance a string of extramarital relationships, a court filing said Friday.Prosecutors are seeking permission "to focus the jury's attention on Mr. Hunter's infidelity" with evidence that isn't necessary for a jury to evaluate the case, they wrote. To allow it would present "substantial risk of unfair prejudice."Allegations about the married Republican congressman's affairs were outlined in a government court filing Monday, connected to charges he and his wife illegally spent more than 0,000 in campaign funds on trips, meals and other personal expenses.Prosecutors are seeking permission to introduce details of the romantic affairs in U.S. District Court in San Diego, which they say are necessary to "demonstrate Hunter's ... intent to break the law and to establish his motive to embezzle from his campaign."Margaret Hunter pleaded guilty this month to one corruption count. Duncan Hunter has said prosecutors have targeted him for political reasons.The trial is scheduled for September.In the motion, Hunter's lawyers argued that "whether or not Mr. Hunter has an intimate or strictly platonic relationship with a particular individual does not tend to prove any material point in the government's case."The said "nearly every expense" listed in the prosecutors' motion Monday seeking to introduce the evidence "was incurred in connection with a legitimate political activity."They said the allegations are so controversial "that merely filing the motion has tainted the jury pool against Mr. Hunter.""However unpopular the notion of a married man mixing business with pleasure, the government cannot simply dismiss the reality that Mr. Hunter's relationships ... often served an overtly political purpose that would not have existed irrespective of his occupation," they added.Separately, Hunter's lawyers are seeking to dismiss the indictment and move the trial out of San Diego County. 2093
