Teen used ‘ghost gun’ in California high school shooting

LOS ANGELES (AP) — The teenager who shot five classmates, killing two, at a Southern California high school used an unregistered “ghost gun,” Los Angeles County Sheriff Alex Villanueva said Thursday.
Villanueva told media outlets Thursday that 16-year-old Nathaniel Tennosuke Berhow’s .45 caliber semi-automatic pistol was assembled from gun parts and did not have a serial number.
