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.

LOS ANGELES (AP) — One of the deadliest accidents in recent U.S. maritime history was the fault of the owners of a dive boat whose lack of oversight resulted in a fire that swept through the vessel and killed all 34 people in their bunks below deck. The National Transportation Safety Board says Tuesday the Conception's captain failed to post a roving night watchman aboard the Southern California scuba dive vessel, which allowed the fire to quickly spread and trap the 33 passengers and one crew member. The NTSB also faulted the Coast Guard's inadequate regulations. Attorneys for the boat's owner and the captain did not immediately respond to requests for comment. 678

LONDON (AP) — Archaeologists said Monday that they have discovered a major prehistoric monument under the earth near Stonehenge that could shed new light on the origins of the mystical stone circle in southwestern England.Experts from a group of British universities say the site consists of at least 20 huge shafts, more than 10 meters, or 32 feet, in diameter and 5 meters deep, forming a circle more than 2 kilometers— over a mile — in diameter.Researchers say the shafts appear to have been dug around 4,500 years ago.Scientists believe the shafts could mark the boundary of a sacred area or precinct around a circular monument known as the Durrington Walls henge, about 3 kilometers, or 2 miles, from Stonehenge.The Guardian obtained a photo of the new discovery. 776

LOS ANGELES (AP) — Deputies arrested a 13-year-old boy and seized a semi-automatic rifle after he threatened to shoot other students and staff at a Los Angeles-area middle school, authorities said Friday.In a separate case, a boy at another school was taken into custody involving a planned shooting.The arrests came barely a week after deputies were frantically summoned to a high school in Santa Clarita, where a 16-year-old boy killed two fellow students and took his own life.Since then, the Los Angeles County Sheriff’s Department has investigated at least 30 school threats, spokesman Sgt. Bob Boese said.RELATED: Santa Clarita high school shooting: 2 killed, 3 hurt; suspected shooter in 'grave' conditionThe incidents that resulted in the arrests were the only ones deemed credible.At Animo Mae Jemison Charter Middle School in Willowbrook, just south of downtown Los Angeles, multiple students overheard the 13-year-old say Thursday that he would carry out the shooting on campus the following day, Sheriff Alex Villanueva said.The students alerted teachers and police were notified.Deputies searched the boy’s home and discovered an AR-15-style rifle, 100 rounds of ammunition, a list of names and a drawing of the school, Villanueva said.The boy was arrested without incident on suspicion of making criminal threats. An adult male relative also was arrested and could face weapons charges, Boese said.RELATED: Teen used ‘ghost gun’ in California high school shootingInvestigators were trying to determine who owns the gun that authorities initially called a ghost gun — a weapon without a serial number made from parts from other guns. Villanueva later clarified the weapon has a serial number.Villanueva praised school officials for quickly notifying authorities about the threat.“The fact that people stepped forward and said what they had heard led us to prevent a tragedy today,” he said.The other boy was arrested Thursday in Palmdale, north of Los Angeles. Villanueva said the student at Knight High School made threats on social media following a campus fight.The sheriff said the boy acknowledged posting threats along with pictures of a teen with a gun. No weapon was recovered in the case.RELATED: Trauma Surgeons call for urgent intervention after school shootingThe sheriff’s department still hasn’t determined a motive for the deadly Nov. 14 shooting at Saugus High School in Santa Clarita.Villanueva said the . semi-automatic pistol used by gunman Nathaniel Berhow was assembled from gun parts and did not have a serial number. Police have not determined where and when Berhow got the gun.___Associated Press reporters Brian Melley and Michael R. Blood in Los Angeles contributed to this report. 2728
