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 (CNS) - Gov. Gavin Newsom said Monday he understands the frustrations of people who have been protesting police brutality across the state, but he lashed out at those who are taking advantage of the unrest to engage in looting.Newsom also declined to directly respond to comments made by President Donald Trump in a conference call with the nation's governors Monday morning, in which the president called many of their responses to protests "weak.""I have a choice. We all have a choice," Newsom said. "I can be part of the daily back and forth in the news cycle, and to continue to perpetuate the problems that persist in this country. I can choose to go back and forth and just be another voice in that cause. Or I can choose to focus a message that I think is so much more powerful that I hope has more resonance for people watching, and that is I care more about them than some of the noise I heard on a morning phone call."RELATED: Looters smash windows, rob stores in downtown San DiegoNewsom expressed solidarity with protesters and their call for change in a system that has failed communities for generations."The black community is not responsible for what's happening in this country right now. We are," he said. "Our institutions are responsible. We are accountable to this moment."RELATED: La Mesa community comes together to clean up downtown after Saturday riotsBut he said he had no patience for those who are taking advantage of the protests to engage in lawlessness."When you're out there to exploit conditions, not advance the cause of justice -- that is not serving the greater good," he said. "And we need to also call that out. The looting, the violence, the threats against fellow human beings -- that has no place in this state and in this nation. We as a society need to call that out."RELATED: San Diego County law enforcement denounce George Floyd's deathHe said another 1,100 members of the National Guard have been called up to assist cities across the state cope with the protests and violence, bringing the total to about 4,500. But he said the state and nation as a whole need to do more than just respond to the protests on the streets."We are committed and resolved to bringing peace back to the streets, not only in the state but supporting efforts all across this nation," he said. "But it's not just a situational moment. we have to focus on the medium and long-term and we have to prove our commitment and our resolve in that space." 2492
