The weapon used in last week’s deadly mass shooting at Saugus High School was a so-called “ghost gun,” a firearm without a registration number, officials at the Los Angeles County Sheriff’s Department said on Thursday.
Homicide detectives are looking for evidence regarding who purchased and assembled the firearm components and investigating the shooter’s purchase history by examining electronic devices seized from his home.
Police say Nathan Berhow came to school the morning of Nov. 14, his 16th birthday, and opened fire with the .45-caliber handgun in the Santa Clarita high school’s quad. Five students were shot, with two later dying, before Berhow turned the weapon on himself. He later died.
“The (detectives’) report on the firearm indicates that the handgun used in the assault was not manufactured conventionally and may be some form of a ‘kit gun,’ one that is assembled by a consumer — rather than a manufacturer — from pieces bought separately,” sheriff’s Capt. Kent Wegener wrote in a statement. “We have no evidence to indicate who assembled it or bought the components.”
Wegener said detectives are still investigating social-media leads and looking for accounts belonging to the suspect. With assistance from the Secret Service, deputies are searching the contents of technology devices recovered from his home such as tablets, computers and cellphones.

Paperwork from the home will be examined “to see if it contains any evidence related to the subject’s state of mind, or historical information about the weapon used,” Wegener added.
In a search of the boy’s home last week, law enforcement found several firearms, some of which were not registered. His father, who died of a heart attack almost two years ago, was described in an online obituary as an avid sportsman who “loved big-game hunting.”
So-called ghost guns are legal weapons manufactured from mail-order parts or machined parts acquired from underground suppliers; they are untraceable because they lack serial numbers. Many are easy to assemble and can be purchased at gun shows in kit form.
High-profile cases in Southern California in recent years suggest a rise in the proliferation of ghost guns, which pose investigative challenges for authorities.
In August, one was used by a convicted felon who fatally shot California Highway Patrol officer Andre Moye Jr. during a lengthy gun battle following a traffic stop in Riverside. authorities said. In Santa Monica, gunman John Zawahri in 2013 killed five people using a rifle with assembled parts shipped from out of state and therefore lacking a serial number.
